74VHC163SJ

Counter Dividers Overview

The onsemi 74VHC163SJ is a 4-bit binary counter with synchronous clear, housed in a 16-SOP package. It operates within a supply voltage range of 2.0V to 5.5V and supports temperatures from -40°C to +85°C. The device features a maximum clock frequency of 185 MHz at 5V and includes two count enable inputs (CEP, CET) for cascading. It utilizes D-type edge-triggered flip-flops with parallel data loading capabilities.

Counter Dividers Feature Summary

• Synchronous counting and presettable architecture
• High-speed operation with low power dissipation
• Input protection circuitry for interfacing mismatched supply voltages

Counter Dividers Applications

• Programmable frequency dividers
• Multistage counter implementation
• Digital timing circuits

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'SJ' corresponds to the EIAJ TYPE II SOP package. Confirm RoHS compliance status as the datasheet indicates lead-free options. Check current manufacturing status as distributors may list obsolete stock. Ensure pinout compatibility with existing PCB layouts before procurement.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous modulo-16 counting with high noise immunity. It is suitable for systems needing interface between 5V and 3V logic levels due to input protection. Consider the 16-SOP package constraints for board space. Verify that the synchronous clear function meets system reset requirements compared to asynchronous alternatives.

Counter Dividers Part Context

This part belongs to the 74VHC series of advanced high-speed CMOS devices. It is functionally compatible with the 74HC163 but offers improved speed characteristics. The device is manufactured using silicon gate CMOS technology to achieve performance similar to Bipolar Schottky TTL while maintaining low power consumption.
