MM54HCT109/MM74HCT109
Dual J-K Flip-Flops with Preset and Clear
General Description
These high speed J-K FLIP-FLOPS utilize advanced silicon-
gate CMOS technology. They possess the low power con-
sumption and high noise immunity of standard CMOS inte-
grated circuits, along with the ability to drive 10 LS-TTL
loads.
Each flip flop has independent J, K, PRESET, CLEAR, and
CLOCK inputs and Q and Q outputs. These devices are
edge sensitive to the clock input and change state on the
positive going transition of the clock pulse. Clear and preset
are independent of the clock and accomplished by a low
logic level on the corresponding input.
The 54HCT/74HCT logic family is functionally as well as
pin-out compatible with the standard 54LS/74LS logic fami-
ly. All inputs are protected from damage due to static dis-
charge by internal diode clamps to V
CC
and ground.
MM54HCT/MM74HCT devices are intended to interface be-
tween TTL and NMOS components and standard CMOS
devices. These parts are also plug-in replacements for LS-
TTL devices and can be used to reduce power consumption
in existing designs.
