CD4060B Overview

The CD4060B is a CMOS integrated circuit that combines an oscillator section with a 14-stage ripple-carry binary counter. It is designed to generate a clock signal and divide it into multiple lower-frequency outputs within a single compact device. The oscillator supports both RC and crystal configurations, allowing flexible and stable design.

The CD4060B is an improved version of the original CD4060, offering better noise immunity, more stable performance, and enhanced input/output characteristics. Each counter stage uses master-slave flip-flops and advances on the negative clock transition, dividing the frequency step by step. The built-in Schmitt trigger input ensures clean signal operation even with slow inputs.

A RESET input clears all stages and disables oscillation when activated. It also supports a wide voltage range and comes in various package types. If you are interested in purchasing the CD4060B, feel free to contact us for pricing and availability.

Logic Diagram of CD4060B

The logic diagram of the CD4060B shows two main sections: the oscillator and the ripple-carry binary counter. On the left side, the oscillator is formed using inverters and logic gates connected to external components. This section generates a stable clock signal that drives the entire circuit. The Schmitt trigger action helps clean the input signal, ensuring reliable switching even with slow or noisy signals.

The clock signal is then fed into a chain of flip-flops starting from FF1. Each flip-flop divides the frequency by two, and the output of one stage becomes the input of the next stage. This creates a ripple effect, producing multiple divided outputs such as Q4 to Q14. The RESET line overrides all stages, forcing the outputs to zero and stopping the counting process.

CD4060B Functional Block Diagram

The functional block diagram of the CD4060B shows a single integrated system that combines an oscillator and a 14-stage ripple-carry binary counter. The oscillator section, connected through pins φI, φO, and external components, generates the clock signal that drives the internal counter. This clock is the main timing source for the entire device.

The generated clock signal is passed into the counter block, where it is divided step by step. Each output pin (Q4 to Q14) provides a different divided frequency, allowing multiple timing signals from one input source. The RESET pin (R) controls the entire counter by clearing all outputs to zero when activated. Power is supplied through VDD and VSS, enabling stable operation of both the oscillator and counter sections.

Specifications of CD4060B

Features of CD4060B

High Clock Frequency Operation

The CD4060B supports clock operation up to 12 MHz at 15 V, allowing it to handle fast timing signals. This makes it suitable for circuits that require stable and consistent frequency division without performance loss.

Common Reset Function

The device includes a common reset input that clears all counter stages at once. When activated, it forces all outputs to zero and ensures the circuit starts from a known state.

Fully Static Operation

The IC operates in a fully static mode, meaning it can maintain its state without a continuous clock. This improves reliability and reduces the risk of data loss during slow or interrupted signals.

Buffered Inputs and Outputs

All inputs and outputs are buffered to provide better signal strength and isolation. This helps reduce loading effects and ensures stable communication between connected components.

Schmitt Trigger Input

The input pulse line includes Schmitt trigger action, which improves noise immunity. It allows the IC to handle slow or noisy signals while maintaining clean and accurate switching.

Low Quiescent Current

The CD4060B is designed with low power consumption in mind and is tested for quiescent current at high voltage levels. This makes it efficient for long-term and low-power operations.

Symmetrical Output Characteristics

The IC provides standardized and symmetrical output characteristics across different voltage levels. This ensures balanced performance and predictable behavior in digital circuits.

Wide Voltage Compatibility

It supports multiple parametric ratings such as 5 V, 10 V, and 15 V operation. This flexibility allows it to be used in a wide range of circuit designs with different power requirements.

Built-in Oscillator Flexibility

The oscillator section includes all active components on-chip and supports both RC and crystal configurations. It can achieve stable oscillation, with RC oscillator frequency reaching around 690 kHz minimum at 15 V.

CD4060B Working in Circuit

The CD4060B in this circuit operates as a timer by generating clock pulses through its internal oscillator section. The timing components, including resistors and capacitors connected to the oscillator pins, control the oscillation frequency. This frequency determines how fast the internal 14-stage counter advances. The reset network ensures the counter starts from zero when powered, providing a stable and predictable timing sequence.

As the clock pulses are generated, the counter stages divide the frequency and produce delayed outputs at different pins. One selected output is routed through a resistor to drive a transistor, which acts as a switch. When the selected output goes high after a specific count, it turns on the transistor, allowing current to flow through the relay coil.

The relay then activates the external load, while the diode protects the circuit from voltage spikes. Control switches allow start and stop functions, making the circuit stable and easy to manage.
