Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AAE' corresponds to the 48-pin 173 mil wide plastic TSSOP package as documented in the ordering information. Confirm that the component meets Pb-free and Green specifications required by your assembly process. Ensure compatibility with LCX and LVT families if replacing existing logic components in the design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring bidirectional data transfer between 3.3V and 5V domains. The 16-bit width reduces pin count compared to 8-bit alternatives. Consider the 173 mil TSSOP package for space-constrained PCB layouts. Verify input voltage levels match the 3V or 5V tolerance requirements of the connected bus lines.
