Description
• Hysteresis on Clock Inputs for Improved Noise Immu-
nity and Increased Input Rise and Fall Times
The Harris CD74HC107 and CD74HCT107 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.
