PI5C3125 PI5C3126 4-Bit Bus Switch with Individual Enables Features Description Pericom Semiconductors PI5C3125 and PI5C3126 are 4-bit Bus Near-Zero propagation delay Switches designed with four individual 5 bus switches with fast 5 switches connect inputs to outputs indiviual enables in an industry standard 74XX125/126 pinout. Direct bus connection when switches are ON When enabled via the associated Bus Enable (BE) pin, the A pin is directly connected to the B pin for that particular gate. The Ultra Low Quiescent Power (0.1A typical) bus switch introduces no additional propagation delay or additional Ideally suited for notebook applications ground bounce noise. Packaging (Pb-free & Green available): The PI5C3125 device has active LOW enables, and the PI5C3126 16-pin 150-mil wide plastic QSOP (Q) has active HIGH enables.
