74ACT323
8-Bit Universal Shift/Storage Register with
Synchronous Reset and Common I/O Pins
General Description
The ACT323 is an 8-bit universal shift/storage register with
3-STATE outputs. Parallel load inputs and flip-flop outputs
are multiplexed to minimize pin count. Separate serial
inputs and outputs are provided for Q
easy cascading. Four operation modes are possible: hold
(store), shift left, shift right and parallel load.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
