It selects one of four data sources per multiplexer based on a common select bus, making it a straightforward choice for data routing in 5V logic systems. The supply range is 4.5V to 5.5V, single-rail only, so it fits legacy 5V buses but not mixed-voltage or 3.3V domains. The commercial temperature grade (0°C to 70°C) limits it to indoor, non-condensing environments — no industrial or automotive use without qualification data. ## Output drive and fan-out limits Output drive is rated 2.6 mA source and 24 mA sink. The 24 mA sink is typical for 74ALS and can drive up to 10 standard TTL loads; the source side is weaker, so check the input current of the downstream device before committing the BOM line. No special MSL handling beyond standard Level 1 — no bake required before reflow unless the tube has been exposed to high humidity.","metaTitle":"SN74ALS153D Texas Instruments Dual 4:1 Multiplexer 16-SOIC","metaDescription":"SN74ALS153D Texas Instruments dual 4:1 multiplexer, 2 x 4:1 circuit, single 4.5V-5.5V supply, 0°C-70°C, 16-SOIC.

The 74ALS family offers lower power consumption and higher speed than the original LS series, but the pinout and function are identical.
