Description
Pericom Semiconductor’s PI74LPT16373 is a 16-bit transparent
latch designed with 3-state outputs and are intended for bus oriented
applications. The Output Enable and Latch Enable controls are
organized to operate as two 8-bit latches or one 16-bit latch. When
Latch Enable (LE) is HIGH, the flip-flops appear transparent to
the data. The data that meets the set-up time when LE is LOW is
latched. When OE is HIGH, the bus output is in the high impedance
state.
The PI74LPT16373 can be driven from either 3.3V or 5.0V
devices allowing this device to be used as a translator in a mixed
3.3/5.0V system.
