LOW-VOLTAGE  
74CBTLV3251  
8:1 MULTIPLEXER/  
DEMULTIPLEXER  
FEATURES:  
DESCRIPTION:  
• Functionally equivalent to QS3251  
• 5Ω bi-directional switch connection between two ports  
• Isolation under power-off conditions  
• Over-voltage tolerant  
The CBTLV3251 is a 1-of-8 high-speed multiplexer/demultiplexer. The  
low on-state resistance of the switch allows connections to be made with  
minimalpropagationdelay.  
The select input (S0, S1, S2) controls the data flow. The multiplexer/  
demultiplexer switches are disabled when the output-enable (OE) input is  
high.  
• Latch-up performance exceeds 100mA  
• VCC = 2.3V - 3.6V, Normal Range  
• ESD > 2000V per MIL-STD-883, Method 3015;  
> 200V using machine model (C = 200pF, R = 0)  
• Available in QSOP and TSSOP packages  
To ensure that the device is in high-impedance state during power up or  
powerdown,OEshouldbetiedtoVCC throughapullupresistor;theminimum  
value of the resistor is determined by the current-sinking capability of the  
driver.
