Datasheet
1. General description
The 74CBTLVD3245 is an 8-pole, single-throw bus switch. The device features a single
output enable input (OE
) that controls eight switch channels. The switches are disabled
when OE
is HIGH. Schmitt trigger action at control inputs makes the circuit tolerant of
slower input rise and fall times. This device is fully specified for partial power-down
applications using I
OFF
. The I
OFF
circuitry disables the output, preventing the damaging
backflow current through the device when it is powered down.
2. Features and benefits
