MM74HCT373 MM74HCT374
3-STATE Octal D-Type Latch
3-STATE Octal D-Type Flip-Flop
General Description
The
MM74HCT373
octal
D-type
latches
and
MM74HCT374 Octal D-type flip flops advanced silicon-gate
CMOS technology, which provides the inherent benefits of
low power consumption and wide power supply range, but
are LS-TTL input and output characteristic & pin-out com-
patible. The 3-STATE outputs are capable of driving 15 LS-
TTL loads. All inputs are protected from damage due to
static discharge by internal diodes to VCC and ground.
When the MM74HCT373 LATCH ENABLE input is HIGH,
the Q outputs will follow the D inputs. When the LATCH
ENABLE goes LOW, data at the D inputs will be retained at
the outputs until LATCH ENABLE returns HIGH again.
When a high logic level is applied to the OUTPUT CON-
TROL input, all outputs go to a high impedance state,
regardless of what signals are present at the other inputs
and the state of the storage elements.
The MM74HCT374 are positive edge triggered flip-flops.
Data at the D inputs, meeting the setup and hold time
requirements, are transferred to the Q outputs on positive
going transitions of the CLOCK (CK) input. When a high
logic level is applied to the OUTPUT CONTROL (OC)
input, all outputs go to a high impedance state, regardless
of what signals are present at the other inputs and the state
of the storage elements.
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.
