The 74F194 4-bit bidirectional universal shift register is a Philips Semiconductors integrated circuit. The product has the ability to shift right and left, can synchronously transfer parallel and serial data, is easily expandable for both serial and parallel operation, has an asynchronous master reset function, and has a hold (do nothing) mode.
This document is a product specification for the Philips 74F194 4-bit bidirectional universal shift register. The device features synchronous parallel and serial data transfer, shift right and shift left capabilities, and an asynchronous master reset. It is designed for high-speed applications with a typical operation time of less than 9ns.
| Supply Voltage | 4.5V to 5.5V |
|---|---|
| Operating Temperature | 0°C to +70°C |
The asynchronous Master Reset (MR) overrides all other input conditions and forces the Q outputs Low when active.
All operations take place in less than 9ns (typical) for the 74F series.
