DESCRIPTION:
The LVC16373A 16-bit transparent D-type latch is built using advanced
dual metal CMOS technology. This high-speed, low-power latch is ideal
for temporary storage of data. The LVC16373A can be used for implement-
ing memory address latches, I/O ports, and bus drivers. The Output Enable
and Latch Enable controls are organized to operate each device as two 8-
bit latches or one 16-bit latch. Flow-through organization of signal pins
simplifies layout. All inputs are designed with hysteresis for improved noise
margin.
All pins of the LVC16373A 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 supply system.
The LVC16373A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
