PI3B3253 Datasheet Mux/demux Nanoswitch

Manufacturer: Pericom Semiconductor (now Diodes Incorporated)

Overview: PI3B3253 3.3V, Dual 4:1 Mux/DeMux NanoSwitch™.

General Description

Pericom Semiconductor’s PI3B3253 is a 3.3V, Dual4:1 Multiplexer/ Demultiplexer with Hi-Z outputs that is pinout compatible with the PI74FCT253T, 74F253, and 74ALS/AS/LS 253.

Inputs can be connected to outputs with low On-Resistance (5Ω) with no additional ground bounce noise or propagation delay.

• Packaging (Pb-free & Green available): – 16-pin 150-mil wide plastic QSOP (Q) – 16-pin 150-mil wide plastic SOIC (W) – 16-pin 173-mil wide plastic TSSOP (L) Block Diagram IA0 SW Pin Configuration IA1 IA2 IA3 IB0 IB1 IB2 IB3 EA EB S0 S1 SW SW SW SW SW SW SW SW I E Y EA 1 16 VCC S1 2 15 EB IA3 3 14 S0 IA2 4 13 IB3 IA1 5 12 11 10 9 IB2 IA0 6 IB1 YA 7 IB0 GND 8 YB YA YB Truth Table(1) Enable EA H X L L L L EB X H L L L L Select S1 X X L L H H S0 X X L H L H YA Hi-Z X IA 0 IA 1 IA 2 IA 3 Pin Description YB X Hi-Z IB0 IB1 IB2 IB3 Function Disable A Disable B S1-0 = 0 S1-0 = 1 S1-0 = 2 S1-0 = 3 Pin Name IAN, IBN S0-1 EA, EB YA, YB GND VCC Description Data Inputs Select Inputs Enable Data Outputs Ground Power Note: 1.
