Description
Pericom Semiconductor’s PI74FCT3 series of logic circuits are
produced in the Company’s advanced 0.6 micron CMOS technology,
achieving industry leading speed grades.
The PI74FCT3573 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 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 PI74FCT3573 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.
