Product Description:
Pericom Semiconductor’s PI74FCT series of logic circuits are pro-
duced in the Company’s advanced 0.8 micron CMOS technology,
achieving industry leading speed grades.
The PI74FCT151T, PI74FCT251T, and PI74FCT2151T are high-
speed 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.
