74VHC163N

Counter Dividers Overview

The onsemi 74VHC163N is a high-speed synchronous modulo-16 binary counter fabricated with silicon gate CMOS technology. It features four fundamental modes: synchronous reset, parallel load, count-up, and hold. The device operates within a supply voltage range of 2.0V to 5.5V and supports an operating temperature range of -40°C to +85°C. It utilizes D-type edge-triggered flip-flops with inputs active on low logic levels for presetting and clearing.

Counter Dividers Feature Summary

• Synchronous counting and loading capabilities
• High-speed synchronous expansion via terminal count output
• Power down protection provided on all inputs

Counter Dividers Applications

• Programmable frequency dividers
• Multistage counter implementation
• System timing and control circuits

Counter Dividers Procurement Notes

Verify the specific package configuration and manufacturer origin, as this component was originally manufactured by Fairchild Semiconductor before its acquisition by onsemi. Confirm RoHS compliance status and ensure the ordering code matches the required PDIP-16 package variant. Check for any specific lifecycle or obsolescence notices associated with legacy Fairchild part numbers currently managed under the onsemi portfolio.

Counter Dividers Selection Notes

Select this component when a synchronous clear function is required rather than asynchronous reset. It is suitable for designs needing pin and function compatibility with 74HC163 devices while offering higher speed performance. Consider the input protection circuitry that allows interfacing between 5V and 3V systems without external level shifting components.

Counter Dividers Part Context

This device belongs to the VHC (Very High Speed CMOS) logic family, designed to achieve operation speeds similar to Bipolar Schottky TTL while maintaining low power dissipation. It serves as a direct functional replacement for HC series counters in applications requiring faster clock rates and improved noise immunity characteristics.
