It selects one of four data inputs per channel and routes it to a common output, controlled by a shared select bus and independent output-enable pins. The 2V to 6V supply range lets it bridge 3.3V and 5V logic domains without a level shifter, and the -40°C to 85°C industrial temperature grade suits outdoor telecom cabinets, factory-floor PLC I/O modules, and automotive body electronics that see under-hood ambient heat. ## Supply headroom and output drive Rated for a single supply from 2V to 6V, this part runs on a 3.3V rail with margin for a 3.0V regulator dropout, or on a 5V rail with headroom for a 5.5V transient. The 7.8mA source and sink capability at both high and low output levels is typical for the 74HC family — enough to drive a few CMOS gate inputs or a low-current LED indicator, but not a relay coil or a long backplane trace without a buffer. For a bus that needs to fan out to more than four loads, budget a 74HC244 line driver after the mux. ## Active production — no LTB clock ticking The SN74HC253DT carries an Active lifecycle status with ROHS3 compliance. For a BOM line that needs a dual 4:1 mux in a 16-SOIC footprint, this part is a stable selection for both prototype builds and multi-year production runs.","metaTitle":"SN74HC253DT 74HC Dual 4:1 Multiplexer, 16-SOIC, 2V-6V","metaDescription":"TI SN74HC253DT dual 4:1 multiplexer in 16-SOIC. 2V to 6V supply, -40°C to 85°C.
