Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the required PCB footprint, as this part number typically corresponds to TSSOP-14 packaging. Confirm that the 5.5V input tolerance aligns with your system's maximum signal voltage. Ensure the 16mA drive current meets the load requirements of your destination circuit. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing circuits with differing voltage standards, such as connecting a 1.8V sensor to a 3.3V microcontroller. The wide supply voltage range allows flexibility in power design. Consider the 3-state output feature if bus sharing is required. Verify that the propagation delay characteristics meet the timing constraints of your specific application frequency.
