A product Line of Diodes Incorporated PI3B3125/PI3B3126 3.3V, 4-Bit, 2-Port Nanoswitchw/Individual Enables Features Description Near zero propagation delay Diodes PI3B series of logic circuits are produced using the Companys advanced sub micron CMOS technology, achieving 5 Ohm switches connect inputs to outputs industry leading speed grades. Fast Switching Speed - 4ns max. The PI3B3125 and PI3B3126 are 3.3 Volt, 4-bit bus switches Ultra Low Quiescent Power (0.1A Typical) designed with four individual 5 Ohm bus switches with fast Ideally suited for notebook applications indiviual enables in an industry standard 74XX125/126 pinout. Packages available: When enabled via the associated Bus Enable (BE) pin, the A 14-pin 150 mil wide plastic SOIC (W) pin is directly connected to the B pin for that particular gate. 14-pin 170 mil wide plastic TSSOP (L) The bus switch introduces no additional propagation delay or 16-pin 150 mil wide plastic QSOP (Q) additional ground bounce noise. The PI3B3125 device has active LOW enables, and the PI3B3126 has active HIGH enables.
