Technical details

Automotive-grade inverting buffer with 3-state outputs

The 2V to 3.6V supply range covers both nominal 3.3V and 2.5V rails without a separate level translator. If your design runs a 3.3V rail that dips to 2.7V during cold-crank, this part stays within spec. That matters for engine-bay or transmission-control modules where ambient can hit 105°C and junction temperature climbs higher.

For a production BOM line, this part is a low-risk selection — no forced redesign horizon.

Housed in a 20-TSSOP package (4.40mm width), this is a surface-mount device. The TSSOP footprint is common across many 8-bit bus-interface parts, so a board layout for a standard 20-pin TSSOP buffer will accept this device without a respin.
