3 Description

The SN74LV8T573-EP 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.
