General Description

The DM74LS299 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. Separate outputs are provided for flip-flops Q0 and Q7 to allow easy cascading. A separate active LOW Master Reset is used to reset the register.

Features

■ Common I/O for reduced pin count

■ Four operation modes: shift left, shift right, load and store

■ Separate shift right serial input and shift left serial input for easy cascading

■ 3-STATE outputs for bus oriented applications
