Description
The ’HC112 and ’HCT112 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.
These flip-flops have independent J, K, Set, Reset, and
Clock inputs and Q and
Q outputs. They change state on the
negative-going transition of the clock pulse. Set and Reset
are accomplished asynchronously by low-level inputs.
The HCT logic family is functionally as well as pin-
compatible with the standard LS logic family.
