Dual 1-of-4 multiplexer/demultiplexer

Rev. 4 — 15 December 2011

Product data sheet

1. General description

The 74CBTLV3253 provides a dual 1-of-4 high-speed multiplexer/demultiplexer with two

common select inputs (S0, S1) and two output enable inputs (1OE, 2OE). The low ON

resistance of the switch allows inputs to be connected to outputs without adding

propagation delay or generating additional ground bounce noise. When pin nOE = LOW,

one of the four switches is selected (low-impedance ON-state) with pins S0 and S1. When

pin nOE = HIGH, all switches are in the high-impedance OFF-state, independent of pins

S0 and S1.

To ensure the high-impedance OFF-state during power-up or power-down, nOE should be

tied to the V_CCthrough a pull-up resistor. The minimum value of the resistor is determined

by the current-sinking capability of the driver.

Schmitt trigger action at control input makes the circuit tolerant to slower input rise and fall

times across the entire V_CCrange from 2.3 V to 3.6 V.

This device is fully specified for partial power-down applications using I_OFF

The I_OFFcircuitry disables the output, preventing the damaging backflow current through

the device when it is powered down.
