8-BIT SHIFT/STORAGE REGISTER WITH 3-STATE OUTPUTS

The SN54/74LS323 is an 8-Bit Universal Shift/Storage Register with 3-state outputs. Its function is similar to the SN54/74LS299 with the exception of Synchronous Reset. Parallel load inputs and flip-flop outputs are multiplexed to minimize pin count. Separate inputs and outputs are provided for flip-flops Q0 and Q7 to allow easy cascading.

Four operation modes are possible: hold (store), shift left, shift right, and parallel load. All modes are activated on the LOW-to-HIGH transition of the Clock.

? Common I/O for Reduced Pin Count

? Four Operation Modes: Shift Left, Shift Right, Parallel Load and Store

? Separate Continuous Inputs and Outputs from Q0 and Q7 Allow Easy Cascading

? Fully Synchronous Reset

? 3-State Outputs for Bus Oriented Applications

? Input Clamp Diodes Limit High-Speed Termination Effects

? ESD > 3500 Volts
