74CBTLV3244BQ

8-bit bus switch with 4-bit output enables

The 74CBTLV3244 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.

Features and benefits

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
