The 4 x 2:1 configuration means four independent 2-input multiplexer channels share a common select line and a common output-enable (strobe) — a standard building block for data routing in 5 V logic systems. The 16-SOIC surface-mount package suits automated assembly on mixed-technology boards where through-hole 74LS parts are being phased out. Its 4.75 V to 5.25 V single-supply range and 400 µA / 8 mA output drive (high/low) are typical for the 74LS family, providing enough fan-out for up to ten standard LS loads per output. The commercial temperature grade (0°C to 70°C) limits it to indoor, office, or appliance environments — not for automotive or extended industrial use. ## Active lifecycle — no LTB pressure for production lines The SN74LS158D carries an Active lifecycle status from Texas Instruments, with ROHS3 compliance. ## Sourcing reality — quoted to order through independent distribution If your line needs a firm price and delivery window, submit an RFQ; the desk will check open-market inventory and factory allocation on the day.","metaTitle":"SN74LS158D Multiplexer, 4 x 2:1, 16-SOIC, 0°C to 70°C","metaDescription":"TI SN74LS158D 4 x 2:1 multiplexer in 16-SOIC surface mount. 4.75V–5.25V supply, 400µA/8mA output drive.
