Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against the datasheet, as the ZQL suffix indicates a BGA configuration distinct from standard TSSOP or SSOP variants. Confirm RoHS compliance status and moisture sensitivity level ratings prior to integration. Ensure input pins are tied to defined logic levels when unused to prevent undefined operational states and excessive current consumption.

Buffers, Drivers, Receivers, Transceivers FAQ

Can the SN74LVC16244AZQLR interface directly with 5-V devices?

Yes, the inputs are tolerant up to 5.5 V at any valid VCC, allowing direct interfacing with 5-V devices while the device itself operates at lower voltages.

What is the purpose of the Ioff feature?

The Ioff feature allows voltages to exist on the inputs and outputs even when VCC is 0 V, supporting live insertion and partial power-down modes without causing back-driving currents.
