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.
