It runs from a single supply between 2V and 6V, making it a drop-in for both 3.3V and 5V logic domains without a level translator. The 16-SOIC package (0.154\" body width, 3.90mm) is the standard SOIC-16 footprint used across the 74HC logic family, so the board layout is interchangeable with other 74HCxxx parts in the same package. Rated for -40°C to 85°C, it handles industrial environments — motor drives, PLC I/O modules, outdoor telecom gear — where commercial-temperature parts would drift out of spec. The 7.8mA sink/source output current is typical for the 74HC family at 5V; it drives one or two standard CMOS loads directly but needs a buffer for heavier fan-out or long backplane traces. ## Supply range and logic compatibility The 2V to 6V supply range means this mux works with 5V TTL/CMOS logic and also with 3.3V systems — no separate regulator or level shifter for the mux itself. At 5V the input thresholds are 0.8V low / 2.0V high, so it reads 3.3V outputs as a valid high. At 3.3V supply the thresholds scale proportionally, and the 7.8mA output current drops slightly but still drives a single 3.3V CMOS load. ## Lifecycle and sourcing posture The SN74HC258DR is listed as Active and ROHS3 compliant.","metaTitle":"SN74HC258DR 74HC Multiplexer, 4 x 2:1, 16-SOIC, 2V-6V","metaDescription":"TI SN74HC258DR is a 74HC 4 x 2:1 multiplexer in 16-SOIC.
