74LCX257  
Low Voltage Quad 2-Input Multiplexer  
with 5V Tolerant Inputs and Outputs  
General Description  
Features  
5V tolerant inputs and outputs  
The LCX257 is a quad 2-input multiplexer with 3-STATE  
outputs. Four bits of data from two sources can be selected  
using a Common Data Select input. The four outputs  
present the selected data in true (non inverted) form. The  
outputs may be switched to a high impedance state by  
placing a logic HIGH on the common Output Enable (OE)  
input, allowing the outputs to interface directly with bus-ori-  
ented systems.  
2.3V–3.6V VCC specifications provided  
6.0 ns tPD max (VCC = 3.3V, In Zn), 10 µA ICC max  
Power down high impedance inputs and outputs  
Supports live insertion/withdrawal (Note 1)  
Implements patented noise/EMI reduction circuitry  
Latch-up performance exceeds 500 mA  
ESD performance:  
The 74LCX257 is fabricated with advanced CMOS technol-  
ogy to achieve high speed operation while maintaining  
CMOS low power dissipation.  
Human body model > 2000V  
Machine model > 200V  
Note 1: To ensure the high-impedance state during power up or down, OE  
should be tied to VCC through a pull-up resistor: the minimum value or the  
resistor is determined by the current-sourcing capability of the driver.
