CD74HCT161MT TI Counter IC | 16-SOIC | 4-Bit Binary, Asynchronous Reset

Product Overview

The CD74HCT161MT is a high-speed CMOS 4-bit binary counter from Texas Instruments, featuring asynchronous reset and synchronous parallel load. It is designed for use in high-performance digital systems where low power consumption and noise immunity are critical. The device operates from a 4.5V to 5.5V supply and is compatible with TTL inputs, making it ideal for interfacing with legacy logic families. The 16-SOIC package offers a compact footprint for space-constrained applications.
