SN74HCS573 Octal Transparent D-Type Latches with Schmitt-Trigger Inputs, 3-State

Outputs, and Flow-Through Pinout

1 Features

• Wide operating voltage range: 2 V to 6 V

• Schmitt-trigger inputs allow for slow or noisy input

signals

• Low power consumption

– Typical ICC of 100 nA

– Typical input leakage current of ±100 nA

• ±7.8-mA output drive at 6 V

• Extended ambient temperature range: –40°C to

+125°C, TA

2 Applications

• Parallel data storage

• Digital bus buffer

3 Description

The SN74HCS573 contains eight D-type latches.

All inputs include Schmitt-trigger architecture. All

channels share a latch enable (LE) input and output

enable (OE) input. This device has a flow-through

pinout which allows for easier bus routing.
