CD74HCT573

High Speed CMOS Logic

Octal Transparent Latch, Three-State Output

November 1997

Features

Description

• Common Latch Enable Control

• Common Three-State Output Enable Control

• Buffered Inputs

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.

• Three-State Outputs

• Bus Line Driving Capacity

• Typical Propagation Delay = 12ns at V

= 5V,

C = 15pF, T = 25 C (Data to Output for HC373)

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.

• Fanout (Over Temperature Range)

- Standard Outputs. . . . . . . . . . . . . . . 10 LSTTL Loads

- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads

• Wide Operating Temperature Range . . . -55 C to 125 C

• Balanced Propagation Delay and Transition Times

• Signiﬁcant Power Reduction Compared to LSTTL
