Description

The CD54AC573/3A and CD54ACT573/3A are octal trans-

parent 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-imped-

ance state. The latch operation is independent of the state of

the Output Enable.

The CD54AC573/3A and CD54ACT573/3A are supplied in

20 lead dual-in-line ceramic packages (F sufﬁx).
