74CBTLV3257  
Quad 1-of-2 multiplexer/demultiplexer  
Rev. 4 — 16 December 2011  
Product data sheet  
1. General description  
The 74CBTLV3257 provides a quad 1-of-2 high-speed multiplexer/demultiplexer with  
common select (S) and output enable (OE) inputs. 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 OE = LOW, one of the two switches is selected  
(low-impedance ON-state) with pin S. When pin OE = HIGH, all switches are in the  
high-impedance OFF-state, independent of pin S.  
Schmitt trigger action at control input makes the circuit tolerant to slower input rise and fall  
times across the entire VCC range from 2.3 V to 3.6 V.  
To ensure the high-impedance OFF-state during power-up or power-down, OE should be  
tied to the VCC through a pull-up resistor. The minimum value of the resistor is determined  
by the current-sinking capability of the driver.  
This device is fully specified for partial power-down applications using IOFF  
.
The IOFF circuitry disables the output, preventing the damaging backflow current through  
the device when it is powered down.
