SN74HCS273 Octal D-Type Flip-Flop with Schmitt-Trigger Inputs and Asynchronous

Clear

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

+125°C, TA

2 Applications

• Synchronize data to clock

• Simple memory – 8 bits

3 Description

The SN74HCS273 device contains eight positive-

edge-triggered D-type flip-flops with Schmitt-trigger

inputs, shared asynchronous active low clear (CLR)

input, and shared rising-edge triggered clock (CLK)

input.
