Product data sheet
1. General description
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_OFF. The I_OFF circuitry disables the output,
preventing the damaging backflow current through the device when it is powered down.
