DESCRIPTION
dual metal CMOS technology. This high-speed, low-power latch is ideal
for temporary storage of data. The LVCH16373A 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 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.
This feature allows the use of the device as a translator in a mixed 3.3V/5V
supply system.
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
