Description

General part information

SN74ALS576B Series

These octal D-type edge-triggered flip-flops feature 3-state outputs designed specifically for bus driving. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

These flip-flops enter data on the low-to-high transition of the clock (CLK) input.

The output-enable () input does not affect internal operations of the flip-flops. Old data can be retained or new data can be entered while the outputs are disabled.
