MM74HCT74
Dual D-Type Flip-Flop with Preset and Clear
Features
■ Typical propagation delay: 20ns
■ Low quiescent current: 40A maximum (74HCT Series)
■ Low input current: 1A maximum
■ Fanout of 10 LS-TTL loads
■ Meta-stable hardened
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 VCC and ground.
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.
