- Packages available: - 16-pin 150-mil wide plastic QSOP (Q) - 16-pin 300-mil wide plastic SOIC (S) - 16-pin 150-mil wide plastic SOIC (W) Product Description: Pericom Semiconductor’s PI74FCT series of logic circuits are produced in the Company’s advanced 0.8 micron CMOS technology, achieving industry leading speed grades. The PI74FCT151T, PI74FCT251T, and PI74FCT2151T are highspeed 8-input multiplexers. They select one bit from a source of eight under the control of three select inputs. Both assertion and negation outputs are provided. The PI74FCT151/2151T has a common, active-LOW, Enable input (E). When E is LOW, data from one of eight inputs is directed to the complementary outputs based on the 3-bit code applied to the Select (S0-S2) inputs. The PI74FCT151/2151T can be used as a data routing device from one of eight sources. The PI74FCT251T has a common Active-LOW Output Enable (OE) input. When OE is LOW, data from one of eight inputs is directed to the complementary outputs. When OE is HIGH, both outputs are switched to a high-impedance state allowing multiplexer expansion by tying several outputs together. Logic Block Diagram I7 I6
