Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'G4' against current Texas Instruments documentation to confirm lead-free status and RoHS compliance details. Ensure the TVSOP package drawing matches the target PCB footprint requirements. Confirm that the active status aligns with current design-in recommendations before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require buffering between 5-V logic domains and 3.3-V systems. The dual 4-bit configuration allows independent control of data flow via separate OE inputs. Consider the TVSOP package constraints regarding thermal dissipation and board space availability during the selection process.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle hot insertion?

The device includes Ioff circuitry that disables outputs when powered down to prevent backflow, and power-up 3-state circuitry that places outputs in a high-impedance state during power transitions.

What is the voltage tolerance for inputs?

The device supports 5-V input voltages even when VCC is at 3.3 V, enabling mixed-mode signal operation.
