Description

The CD54AC373/3A and CD54ACT373/3A are octal trans­parent three-state latches that utilize the Harris Advanced
CMOS Logic technology. The outputs are transparent to the
inputs when the Latch Enable (

LE) is HIGH. When the Latch

Enable (

LE) goes LOW, the data is latched. The Output

Enable (

OE) controls the three-state outputs. When the Out-

put Enable (

OE) is HIGH, the outputs are in the high-imped­ance state. The latch operation is independent of the state of
the Output Enable.

The CD54AC373/3A and CD54ACT373/3A are supplied in
20 lead dual-in-line ceramic packages (F suffix).
