8-INPUT UNIVERSAL

SHIFT/STORAGE REGISTER

WITH COMMON

PARALLEL I/O PINS

The MC74AC299/74ACT299 is an 8-bit universal shift/storage register

with 3-state outputs. Four modes of operation are possible: hold (store), shift left,

shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed

to reduce the total number of package pins. Additional outputs are provided for

flip-flops Q , Q to allow easy serial cascading. A separate active LOW Master

Reset is used to reset the register.

• Common Parallel I/O for Reduced Pin Count

• Additional Serial Inputs and Outputs for Expansion

• Four Operating Modes: Shift Left, Shift Right, Load and Store

• 3-State Outputs for Bus-Oriented Applications

• Outputs Source/Sink 24 mA
