Product Description:  
Pericom Semiconductor’s PI74FCT series of logic circuits are  
produced in the Company’s advanced 0.6/0.8 micron CMOS  
technology, achieving industry leading speed grades. All  
PI74FCT2XXX devices have a built-in 25 ohm series resistor on  
all outputs to reduce noise resulting from reflections, thus  
eliminating the need for an external terminating resistor.  
The PI74FCT373T/533T/573T and P174FCT2373T/2573T are  
8-bit wide octal transparent latches designed with 3-state outputs  
and are 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.
