IDT74LVC74A
DESCRIPTION:
This dual positive-edge-triggered D-type flip-flop is built using advanced
dual metal CMOS technology. A low level at the preset (
PRE) or clear (CLR)
inputs sets or resets the outputs, regardless of the levels of the other inputs.

clockpulse.Clocktriggeringoccursatavoltagelevelandisnotdirectlyrelated
to the rise time of the clock pulse. Following the hold-time interval, data at the
D input can be changed without affecting the levels at the outputs.
The LVC74A has been designed with a ±24mA output driver. This driver
is capable of driving a moderate to heavy load while maintaining speed
performance.
Inputs can be driven from either 3.3V or 5V devices. This feature allows the
use of this device as a translator in a mixed 3.3V/5V system environment.
