74F194
4-Bit Bidirectional Universal Shift Register
General Description
The 74F194 is a high-speed 4-bit bidirectional universal
shift register. As a high-speed, multifunctional, sequential
building block, it is useful in a wide variety of applications. It
may be used in serial-serial, shift left, shift right, serial-par-
allel, parallel-serial, and parallel-parallel data register
transfers.
Features
a73 Typical shift frequency of 150 MHz
a73 Asynchronous master reset
a73 Hold (do nothing) mode
a73 Fully synchronous serial or parallel data transfers

Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
