LOW-VOLTAGE

QUAD 2:1MUX/DEMUX

BUS SWITCH

FEATURES:

DESCRIPTION:

• Functionally equivalent to QS3257

• 5Ω bi-directional switch connection between two ports

• Isolation under power-off conditions

• Over-voltage tolerant

The CBTLV3257 is a quad 2:1 multiplexer/demultiplexer. The low on-

state resistance of the switch allows connections to be made with minimal

propagation delay.

Theselect(S)inputcontrolsthedataflow.Themultiplexers/demultiplexers

are enabled when the output-enable (OE) input is low.

To ensure the high-impedance state during power up or power down,

OE should be tied to VCC through a pullup resistor; the minimum value of

the resistor is determined by the current-sinking capability of the driver.

• 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

APPLICATIONS:

• 3.3V High Speed Bus Switching, Multiplexing, and Bus Isolation
