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.
