SNx4HCT273 Octal D-Type Flip-Flops With Clear

1 Features

• Operating voltage range of 4.5 V to 5.5 V

• Outputs can drive up to 10 LSTTL loads

• Low power consumption, 80 µA maximum ICC

• Typical tpd = 12 ns

• ±4 mA output drive at 5 V

• Low input current of 1 µA maximum

• Inputs are TTL-voltage compatible

• Contain eight D-type flip-flops

• Direct clear input

2 Applications

• Buffer or storage registers

• Shift registers

• Pattern generators

3 Description

These devices are positive-edge-triggered D-type flip-

flops with a common enable input. The ’HCT273

devices are similar to the ’HCT377 devices, but

feature a common clear enable (CLR) input instead

of a latched clock.
