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. Ultra Low Quiescent Power (0.1A Typical) e Th PI3B3125 and PI3B3126 are 3.3 Volt, 4-bit bus switches 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, SOIC (W) pin is directly connected to the B pin for that particular gate. 14-pin, TSSOP (L) e bTh us switch introduces no additional propagation delay or 14-pin, TQFN (ZDB) additional ground bounce noise. 16-pin, QSOP (Q) e Th PI3B3125 device has active LOW enables, and the PI3B3126 has active HIGH enables.
