Features

Description

• Hysteresis on Clock Inputs for Improved Noise

Immunity and Increased Input Rise and Fall Times

The Harris CD74HC73 and CD74HCT73 utilize silicon gate

CMOS technology to achieve operating speeds equivalent to

LSTTL parts. They exhibit the low power consumption of

standard CMOS integrated circuits, together with the ability

to drive 10 LSTTL loads.

• Asynchronous Reset

• Complementary Outputs

• Buffered Inputs

These ﬂip-ﬂops have independent J, K, Reset and Clock

inputs and Q and Q outputs. They change state on the

negative-going transition of the clock pulse. Reset is

accomplished asynchronously by a low level input. This

device is functionally identical to the HC/HCT107 but differs

in terminal assignment and in some parametric limits.
