74AC161SCX Description

Short technical summary and product information.

The 74AC161SCX is a synchronous presettable binary counter from ON Semiconductor, designed for high-speed applications. It counts in a modulo-16 binary sequence and features synchronous counting and loading capabilities.

 

This device operates within a voltage range of 2V to 6V and offers a typical count rate of 167 MHz, with a datasheet value of 125 MHz. It includes an asynchronous Master Reset input that overrides all other inputs, forcing outputs LOW. The counter has two types of Count Enable inputs and a Terminal Count output, making it versatile for forming synchronous multistage counters.

 

The 74AC161SCX is available in a 16-SOIC package with surface mount mounting type. Its operating temperature range is -40°C to 85°C. The ACT161 variant offers TTL-compatible inputs.

 

Key features include synchronous operation, high-speed synchronous expansion, and outputs that can source/sink 24 mA. The device is suitable for applications requiring programmable dividers and synchronous multistage counting.
