APPLICATIONS:
− 3.3V High Speed Bus Switching, Multiplexing, and Bus Isolation
DESCRIPTION:
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.
The select (S) input controls the data flow. The multiplexers/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.
