SEMICONDUCTOR TECHNICAL DATA

J SUFFIX

CERAMIC PACKAGE

CASE 732–03

High–Performance Silicon–Gate CMOS

The MC54/74HC373A is identical in pinout to the LS373. The device

inputs are compatible with standard CMOS outputs; with pullup resistors,

they are compatible with LSTTL outputs.

These latches appear transparent to data (i.e., the outputs change

asynchronously) when Latch Enable is high. When Latch Enable goes low,

data meeting the setup and hold time becomes latched.

N SUFFIX

PLASTIC PACKAGE

CASE 738–03

The Output Enable input does not affect the state of the latches, but when

Output Enable is high, all device outputs are forced to the high–impedance

state. Thus, data may be latched even when the outputs are not enabled.

The HC373A is identical in function to the HC573A which has the data

inputs on the opposite side of the package from the outputs to facilitate PC

board layout.

DW SUFFIX

SOIC PACKAGE

CASE 751D–04

SD SUFFIX

SSOP PACKAGE

CASE 940C–03

The HC373A is the non–inverting version of the HC533A.
