1. General description

The 74CBTLV3244-Q100 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 IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current

through the device when it is powered down.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
