Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-24 package configuration required for your design. Confirm the operating temperature range of -40°C to 85°C aligns with your environmental specifications. Ensure compatibility with the 1.65 V to 3.6 V supply voltage requirements. Check for any specific moisture sensitivity level (MSL) or reflow soldering profile constraints associated with this package type before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional data transfer between 10-bit buses operating at low voltages. It is suitable for applications needing interface between 3.3-V and 5-V logic levels without external translation components. Consider its Ioff capability if power-down states are critical to the system architecture. Evaluate the TSSOP-24 package dimensions against your PCB layout constraints.
