MC14022BDG

Counter Dividers Overview

The MC14022BDG is a four-stage Johnson octal counter with built-in code converter manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an operating temperature range from -55°C to +125°C. The device features fully static operation, allowing for DC clock inputs with slow rise times. It provides eight decoded outputs that are normally low and go high at their appropriate octal time period. The output changes occur on the positive-going edge of the clock pulse. The component is housed in a 16-SOIC package.

Counter Dividers Feature Summary

• Fully static operation allows for DC clock input circuits with slow rise times.
• Includes a carry out output specifically designed for cascading applications.
• Capable of driving two low-power TTL loads or one low-power Schottky TTL load over the rated temperature range.
• Features triple diode protection on all inputs to guard against damage due to high static voltages.

Counter Dividers Applications

• Frequency division applications
• Octal counter implementations
• Octal decode display applications

Counter Dividers Procurement Notes

Verify the specific ordering suffix to confirm package type and shipping quantity. The 'DG' suffix indicates a Pb-Free SOIC-16 package shipped in rails of 48 units. Confirm RoHS compliance status as required by project specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the semiconductor components.

Counter Dividers Selection Notes

Select this component when an octal decoding sequence is required from a four-bit binary count. It serves as a pin-for-pin replacement for the CD4022B. Consider the wide supply voltage range and robust drive capability if interfacing with TTL logic families. Verify that the application requires positive-edge triggered counting and can accommodate the specified propagation delays and power dissipation limits.

Counter Dividers Part Context

This part belongs to the MC14022B series of octal counters produced by onsemi. It is a CMOS logic device designed for general-purpose digital counting and decoding tasks. The series is known for its compatibility with standard TTL logic levels and its ability to operate reliably across a broad industrial temperature range. The device represents a standard solution for creating sequential timing signals in digital systems.

Counter Dividers Replacement Considerations

The MC14022BDG is a direct pin-for-pin replacement for the CD4022B. Designers should verify electrical parameter compatibility when substituting other manufacturers' octal counters. Ensure that any alternative component meets the same voltage, current, and temperature specifications to maintain system integrity.

Counter Dividers FAQ

How does the MC14022BDG handle unused inputs?

Unused inputs must always be tied to an appropriate logic voltage level, either VSS or VDD, to ensure proper operation and prevent undefined states.

What is the function of the Carry Out (Cout) pin?

The Carry Out output is provided to facilitate cascading multiple MC14022B devices together to extend the number of decoded output states beyond eight.

Can this device drive standard TTL loads?

Yes, the device is capable of driving two Low-Power TTL loads or one Low-Power Schottky TTL load over the entire rated temperature range.
