Buffers, Drivers, Receivers, Transceivers FAQ

Can the SN74LVC16244ADL operate with 5-V inputs?

Yes, the inputs are tolerant to 5.5 V at any valid VCC, allowing use in mixed 3.3-V/5-V system environments.

What is the purpose of the Ioff feature?

The Ioff feature allows voltages to be present on the inputs and outputs when VCC is 0 V, supporting partial-power-down mode and live insertion.
