SN74HC163PW

Counter Dividers Overview

The SN74HC163PW is a synchronous 4-bit binary counter manufactured by Texas Instruments in the HC logic series. It operates within a supply voltage range of 2 V to 6 V and functions across an operating temperature range of -40°C to +85°C. The device utilizes a TSSOP-16 surface-mount package and features positive-edge triggered clocking with synchronous reset and parallel load capabilities.

Counter Dividers Feature Summary

• Synchronous presettable binary counting with internal look-ahead carry for simplified cascading
• Synchronous reset and parallel load operations controlled by dedicated inputs
• Dual count enable inputs (CEP and CET) for flexible n-bit expansion

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division applications
• Event counting systems

Counter Dividers Procurement Notes

Verify component authenticity through authorized channels as the SN74HC163PW has been identified as obsolete or end-of-life status in certain distributor records. Confirm current manufacturing availability and lifecycle status directly with Texas Instruments before finalizing procurement plans to ensure long-term supply stability.

Counter Dividers Selection Notes

Select this component for designs requiring precise synchronous control over counting states without asynchronous glitches. Ensure the system voltage remains within the 2 V to 6 V operational window. Verify that the TSSOP-16 package dimensions align with the printed circuit board layout constraints and thermal management requirements.

Counter Dividers Part Context

This part belongs to the SN74HC163 family of high-speed CMOS logic devices. It serves as a standard solution for 4-bit binary counting tasks where synchronous operation is critical. The HC series offers compatibility with standard CMOS logic levels, distinguishing it from TTL-compatible variants like the HCT series.

Counter Dividers Replacement Considerations

Public confirmed substitute part numbers include SN74HC163DR and SN74HC163NS. These alternatives share identical logical functionality but differ in packaging formats such as SOIC-16.
