The MC74ACT161N is a high-speed synchronous modulo-16 binary counter designed for applications requiring programmable dividers. It features synchronous counting and loading capabilities, with a typical count rate of 125 MHz. The device includes an asynchronous Master Reset input that forces all outputs low, and it supports two types of Count Enable inputs, enhancing its versatility for forming synchronous multistage counters. The outputs can source or sink up to 24 mA, and the device is compatible with TTL logic levels. It is available in a Pb-free package, making it suitable for modern electronic applications.
