It operates from a single 2V to 6V supply, which means it can sit on a 5V or 3.3V logic bus without a level translator. ROHS3 compliant per the listing, which keeps it clear of the EU RoHS exemption phase-outs. For a 74HC logic part that has been in production for decades, active status means TI still runs it through its standard wafer fabs and assembly lines — you are not chasing surplus stock. ## 5V supply compatibility — yes, and 3.3V too The 2V to 6V supply range covers 5V logic operation directly. At 5V VCC, the HC family input thresholds accept standard 5V CMOS and TTL levels.","metaTitle":"SN74HC257DT Multiplexer 4 x 2:1, 2V-6V, 16-SOIC","metaDescription":"Texas Instruments SN74HC257DT 4 x 2:1 multiplexer, 2V to 6V supply, 7.8mA output drive, -40°C to 85°C, 16-SOIC.
