74HC161D,653 Presettable Synchronous 4-bit Binary Counter IC | High-Speed CMOS | SOIC-16 SMD

Description

The 74HC161D,653 is a high-speed, presettable synchronous 4-bit binary counter. This device is designed for synchronous counting applications where all flip-flop outputs change state simultaneously in response to the positive-going edge of the clock signal, effectively eliminating the output glitches often seen in ripple counters. The counter features parallel load inputs for presetting, which are fully synchronous with the clock.

Built using advanced silicon-gate CMOS technology, this IC combines the high-speed operation of standard Schottky TTL with the low power consumption and high noise immunity of the HC logic family. Its versatility, including internal look-ahead logic for high-speed counting and multiple enable inputs, makes it ideal for complex timing and sequencing in digital systems. The SOIC-16 surface-mount package is optimized for space-efficient PCB design.
