IDT74CBTLV3251
DESCRIPTION:
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
minimal propagation delay.
The select input (S0, S1, S2) controls the data flow. The multiplexer/
demultiplexer switches are disabled when the output-enable (OE) input is
high.
To ensure that the device is in high-impedance state during power up
or power down,
OE
should be tied to V
CC
through a pullup resistor; the
minimum value of the resistor is determined by the current-sinking capability
of the driver.
