Product Description
Pericom Semiconductor’s PI3B series of logic circuits are produced
using the Company’s advanced sub micron CMOS technology,
achieving industry leading performance.
The PI3B3251 is a 3.3V Dual 8:1 Multiplexer/demultiplexer with three-
state outputs that is pinout compatible with the PI74FCT251T,
74F251, and 74ALS/AS/LS 251. Inputs can be connected to outputs
with low on resistance (5 Ohm) with no additional ground bounce
noise or propagation delay.
