Overview
The SN74HC163D is a 4-bit synchronous binary counter produced by Texas Instruments. This integrated circuit is part of the 74HC series and is designed for high-speed counting applications. It features synchronous operation, which means all flip-flops are clocked simultaneously, eliminating output counting spikes associated with ripple-clock counters. The device is fully programmable and can be preset to any number between 0 and 15. It also includes a synchronous clear function and internal carry look-ahead for easy cascading in n-bit synchronous applications.
