Pericom Semiconductor’s PI74LPT373 is an 8-bit transparent
latch designed with 3-state outputs and is intended for bus oriented
applications. When Latch Enable (LE) is HIGH, the fl ip-fl ops 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 PI74LPT373 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.
