MM74HC373N
3-STATE Octal D-Type Latch
General Description
The MM74HC373 high speed octal D-type latches utilize
advanced silicon-gate CMOS technology. They possess
the high noise immunity and low power consumptioof
standard CMOS integrated circuits, as well as the ability to
drive 15 LS-TTL loads. Due to the large output drive capability and the 3-STATE feature, these devices are ideally
suited for interfacing with bus lines ia bus organized system.
Whethe LATCH ENABLE input is HIGH, the Q outputs
will follow the D inputs. Whethe LATCH ENABLE goes
LOW, data at the D inputs will be retained at the outputs
until LATCH ENABLE returns HIGH again. Whea high
logic level is applied to the OUTPUT CONTROL 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 74HC logic family is speed, function, 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.
