An 74LS194N 4-Bit Bidirectional Universal Shift Register is a high-speed Low-Power Schottky (LS) TTL logic Integrated Circuit (IC) designed for versatile data manipulation, storage, and conversion. Encapsulated in a standard 16-pin Dual In-line Package (DIP-16), it features four distinct operating modes controlled by two mode select inputs (S0, S1): Hold (do nothing), Shift Right, Shift Left, and Parallel Load. Printed clearly with part number "74LS194N", it contains an asynchronous Master Reset (CLR) input that instantly overrides all other inputs to clear all register outputs to a logic low state.

This product is featured by Famephase Electronic Accessories as an essential digital logic component for serial-to-parallel data conversion, parallel-to-serial data conversion, ring/Johnson counters, shift-register storage buffers, and hardware state machines.
