(1) PERICOM PI74FCT373T/533T/573T (25Q Series) P174FCT2373T/2573T OCTAL TRANSPARENT LATCHES Product Features: PI74FCT373/533/573/2373/2573T is pin compatible with bipolar FAST Series at a higher speed and lower power consumption 25Q series resistor on all outputs (FCT2XXX only) TTL input and output levels Low ground bounce outputs Extremely low static power Hysteresis on all inputs Industrial operating temperature range: -40C to +85C Packages available: 20-pin 173 mil wide plastic TSSOP (L20) 20-pin 300 mil wide plastic DIP (P20) 20-pin 150 mil wide plastic QSOP (Q20) 20-pin 150 mil wide plastic TQSOP (R20) 20-pin 300 mil wide plastic SOIC (S20) Device models available upon request Fast CMOS Octal Transparent Latches Product Description: Pericom Semiconductors PI74FCT series of logic circuits are produced in the Companys 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.
