Onsemi MC14060BDR2G: 14-Stage Binary Counter and Oscillator IC

The Onsemi MC14060BDR2G is a highly integrated monolithic CMOS integrated circuit combining a 14-stage ripple-carry binary counter and an on-chip oscillator. This versatile device is designed for a wide range of applications in timing, frequency division, and clock generation, serving as a fundamental component in numerous electronic systems.

At its core, the IC features a built-in oscillator that can be configured using external resistors and a capacitor. This design provides designers with exceptional flexibility in setting the base frequency without requiring additional active components. The oscillator output is internally connected to the counter section, which consists of 14 flip-flops. This results in a massive maximum division ratio of 2^14 (or 16,384), enabling the generation of very long timing delays or extremely low frequencies from a higher-speed clock source.

The counter provides access to ten outputs (Q4 through Q10 and Q12 through Q14), offering a selection of divided frequencies. The ripple counter architecture means that each successive stage divides the frequency of the previous one by two. This makes the MC14060B an ideal choice for applications such as real-time clocks (RTC), programmable timers, frequency synthesizers, and as a time base for digital systems.

A key advantage of this CMOS-based device is its low power consumption across a wide supply voltage range, typically from 3V to 18V. This makes it suitable for both battery-operated portable equipment and industrial line-powered applications. Furthermore, it offers high noise immunity and robust performance, characteristic of the 4000-series CMOS logic family.

Typical applications include:

Long-duration timers for industrial control and appliances.

Frequency division in communication systems.

Generating low-frequency clock signals for microcontrollers.

LED flashers and sequential logic circuits.
