74194 Register 4-bit bidirectional (serial or parallel)

74LS194 The SN74LS194 is a 4-bit high-speed bi-directional universal shift register. Due to its high-speed multifunctional sequential construction, it is useful in a wide variety of applications. It can be used in serial-serial data, Shift Left, Shift Right, Serial-Parallel, Parallel-Serial, and Parallel Parallel Transfers. The LS194A is similar in operation to the LS195A Universal Shift Register, with additional left shift functions without external connections and retention modes (do nothing) of operation. It uses the Schottky Clamp diode process to achieve high-speed and is fully compatible with all TTL family semiconductors.

Typical 36 MHz changeover frequency

Asynchronous Master Reset

Standby mode (do nothing)

Fully synchronous serial or parallel data transfers

Input clamp diodes limit high-speed termination effects
