High Speed CMOS Logic
Octal Transparent Latch, Three-State Output
Description
The Harris CD74HC373, CD74HCT373, CD54HC573,
CD74HC573, and CD74HCT573 are high speed Octal Trans-
parent Latches manufactured with silicon gate CMOS technol-
ogy. They possess the low power consumption of standard
CMOS integrated circuits, as well as the ability to drive 15
LSTTL devices. The CD74HCT373 and CD74HCT573 are
functionally as well as pin compatible with the standard
74LS373 and 74LS573.
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 output enable (OE) is high the
outputs are in the high impedance state. The latch operation
is independent to the state of the output enable. The 373 and
573 are identical in function and differ only in their pinout
arrangements.
