General Description
The MM74HCT74 utilizes advanced silicon-gate CMOS
technology to achieve operation speeds similar to the
equivalent LS-TTL part. It possesses the high noise
immunity and low power consumption of standard
CMOS integrated circuits, along with the ability to drive
10 LS-TTL loads.
This flip-flop has independent data, preset, clear, and
clock inputs and Q and Q outputs. The logic level
present at the data input is transferred to the output
during the positive-going transition of the clock pulse.
Preset and clear are independent of the clock and
accomplished by a low level at the appropriate input.
The 74HCT logic family is functionally and pin-out
compatible with the standard 74LS logic family. All inputs
are protected from damage due to static discharge by
internal diode clamps to V
MM74HCT devices are intended to interface between
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.
