Description
Diodes' PI3B series of logic circuits are produced using the
Company’s advanced sub micron CMOS technology, achieving
industry leading speed grades.
The PI3B3125 and PI3B3126 are 3.3 Volt, 4-bit bus switches
designed with four individual 5 Ohm 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.
