3.3V, 4-Bit, 2-Port Nanoswitch^™
w/Individual Enables
Description
Pericom Semiconductor’s PI3B3125 and PI3B3126 are 3.3 Volt,
4-bit bus switches designed with four individual 5Ω bus switches
with fast indiviual enables in an industry standard 74XX125/126
pinout. When enabled via the associated Bus Enable (BE) pin,
the “A” pin is directly connected to the “B” pin for that particular
gate. The bus switch introduces no additional propagation delay
or additional ground bounce noise.
The PI3B3125 device has active LOW enables, and the PI3B3126
has active HIGH enables.
