SNx4HC573A Octal Transparent D-Type Latches With 3-State Outputs

1 Features

• Wide Operating Voltage Range from 2 V to 6 V

• High-Current 3-State Outputs Drive Bus Lines

Directly up to 15 LSTTL Loads

• Low Power Consumption: 80-µA Maximum ICC

• Typical tpd = 21 ns

• ±6-mA Output Drive at 5 V

• Low Input Current: 1 µA (Maximum)

• Bus-Structured Pinout

2 Applications

• Buffer Registers

• Bidirectional Bus Drivers

• Working Registers

3 Description

The SNx4HC573A devices are octal transparent

D-type latches that feature 3-state outputs designed

specifically for driving highly capacitive or relatively

low-impedance loads. They are particularly suitable

for implementing buffer registers, I/O ports,

bidirectional bus drivers, and working registers.

While the latch-enable (LE) input is high, the

Q outputs respond to the data (D) inputs. When LE is

low, the outputs are latched to retain the data that was

set up.
