Dual 1-of-4 multiplexer/demultiplexer

Rev. 6 — 24 September 2020

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.
