DESCRIPTION:
The 32-bit transparent D-type latch is built using advanced dual metal
CMOS technology. The 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-bit latches, two 16-
bit latches, or one 32-bit latch. Flow-through organization of signal pins
simplifies layout. All inputs are designed with hysteresis for improved noise
margin.
The ALVCH32373 has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
The ALVCH32373 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 resistor.
APPLICATIONS:
• 3.3V high speed systems
• 3.3V and lower voltage computing systems
