1. General description
The 74CBTLV3245 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.
