74LS161 Synchronous 4-Bit Binary Counter IC - DIP-16 Package Raspberry Pi Power Supply Output interface: 6 wire interfaceThe 74LS161 is a high speed synchronous 4 bit binary counter IC from the 74LS logic family. It features synchronous counting, parallel load, asynchronous reset, and enable control inputs, making it ideal for use in frequency division, event counting, and digital clock or timer applications. Unlike asynchronous counters, all internal operations in the 74LS161 are synchronized with the clock input, which ensures reliable and glitch free output
