1. General description

2. Features and benefits

The 74CBTLVD3244 is a dual 4-pole, single-throw bus switch. The device features two

output enable inputs (nOE) that each control four switch channels. The switches are

disabled when the associated nOE input 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

preventing the damaging backflow current through the device when it is powered down.
