3 Description

The SNx4HC573A devices are octal transparent
D-type latches that feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

While the latch-enable (LE) input is high, the
Q outputs respond to the data (D) inputs. When LE is low, the outputs are latched to retain the data that was set up.
