Automotive 74HC buffer with 3-state outputs
The Texas Instruments SN74HC244QDWRG4Q1 is a dual 4-bit non-inverting buffer with 3-state outputs from the 74HC family, qualified to AEC-Q100 for automotive applications. It operates across a 2V to 6V supply range, making it compatible with both 3.3V and 5V logic domains without external level translation. The 7.8mA output current per channel drives typical CMOS and TTL loads in automotive body controllers, infotainment, and ADAS sensor interfaces. The 3-state outputs let multiple devices share a common data bus without contention.
The wide operating range also suits outdoor industrial equipment exposed to direct sunlight or cold soak.
Supplied in a 20-SOIC wide-body package (7.50mm body width), surface-mount. The wide SOIC footprint is common for automotive-grade logic and fits standard reflow profiles.
Listed as Active in production. The part is ROHS3 compliant.
