IDT74LVCH32373A
DESCRIPTION:
The LVCH32373A 32-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 device can be used for implementing
memory address latches, I/O ports, and bus drivers. The Output Enable
and Latch Enable controls are organized to operate each device as four 8-
bitlatches,two16-bitlatches,orone32-bitlatch. Flow-throughorganization
of signal pins simplifies layout. All inputs are designed with hysteresis for
improved noise margin.
All pins of the LVCH32373A 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 LVCH32373A has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
The LVCH32373A has “bus-hold” which retains the inputs’ last state
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
