Part of the 74HC family — high-speed CMOS logic with the same pinout as the original 74LS series but lower power consumption and wider supply tolerance. ## Output drive and package — board-level integration Each output pin sources or sinks 7.8 mA typical — enough to drive standard TTL inputs or a single LED indicator without a buffer.","metaTitle":"SN74HC251DT Texas Instruments 74HC Multiplexer 1x8:1 16-SOIC","metaDescription":"SN74HC251DT — Texas Instruments 74HC 1x8:1 multiplexer, 2V-6V supply, -40°C to 85°C, 16-SOIC.
