74LS164 DIP-14 8-Bit Serial-In Parallel-Out Shift Register IC (TTL, 5V)

Description -

The 74LS164 DIP is a TTL logic integrated circuit that functions as an 8-bit Serial-In Parallel-Out (SIPO) shift register in a 14-pin Dual Inline Package (DIP). It belongs to the 74LS Low Power Schottky logic family and is designed for serial-to-parallel data conversion, data storage, and digital signal processing.

The device accepts serial data through two gated serial inputs and shifts the data into the register on each rising edge of the clock. It also features an asynchronous master reset that instantly clears all outputs regardless of the clock state, making it suitable for microcontroller interfacing, output expansion, and digital control systems.
