Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' against the requested part number if environmental compliance documentation is required. Confirm the SSOP-20 package dimensions match the target PCB footprint. Ensure the operating temperature range aligns with the application environment specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require wide voltage tolerance between 2 V and 5.5 V. The three-state outputs are essential for multiplexed bus applications where multiple devices share data lines. Consider the 16 mA drive strength for driving moderate capacitive loads or standard TTL/CMOS inputs directly.
