Features
Description
• Hysteresis on Clock Inputs for Improved Noise Immu-
nity and Increased Input Rise and Fall Times
The ’HC107 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.
