MC74HC163AFR2

Counter Dividers Overview

The MC74HC163AFR2 is a high-performance silicon-gate CMOS device from the onsemi MC74HC163A series. It functions as a synchronous 4-bit binary counter with a synchronous clear feature, distinguishing it from asynchronous reset variants. The component operates within a supply voltage range of 2.0 V to 6.0 V and features outputs directly interfacing with CMOS, NMOS, and TTL loads. Packaged in a 16-SOEIAJ surface-mount format, it supports positive edge triggering and includes parallel load capabilities for programmable counting sequences.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting operation with positive edge triggering
• Synchronous clear input allowing data retention during active clock cycles
• Parallel load capability for direct presetting of output states
• Compatible interface with standard CMOS, NMOS, and LSTTL logic families

Counter Dividers Applications

• Digital timing and sequencing circuits requiring precise state control
• Frequency division networks in communication systems
• Programmable counters for industrial automation controllers
• Event counting modules in embedded sensor interfaces

Counter Dividers Procurement Notes

Verify the specific suffix FR2 against official datasheets to confirm package type and tape/reel specifications. Confirm RoHS compliance status through manufacturer documentation prior to integration. Check for end-of-life notices or production change notifications that may affect long-term availability. Ensure pinout compatibility with existing PCB footprints before finalizing procurement decisions.

Counter Dividers Selection Notes

Select this component when synchronous reset behavior is required to prevent unintended clearing during clock transitions. Compare against MC74HC161A if asynchronous reset functionality is preferred instead. Evaluate power consumption requirements against the 2V to 6V operating range. Consider the SOEIAJ package constraints for board space and thermal management needs relative to other 16-pin logic options.

Counter Dividers Part Context

This part belongs to the MC74HC163A family of presettable counters manufactured by onsemi. It shares pinout compatibility with legacy LS163 devices while offering improved noise immunity and lower power consumption typical of modern CMOS technology. The HC163A variant specifically provides synchronous clear, ensuring predictable state changes only at clock edges.

Counter Dividers Replacement Considerations

MC74HC163ADG serves as a direct pin-compatible alternative in different packaging. MC74HC161A is functionally similar but utilizes asynchronous clear rather than synchronous clear. Verify electrical characteristics and package dimensions when substituting to ensure circuit integrity.
