Product details

Dual 4:1 multiplexer on a 5V rail

The SN74ALS153D is a dual 4:1 multiplexer from Texas Instruments' 74ALS family, packing two independent 4-input multiplexers into a single 16-SOIC package. 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.

Frequently asked questions

Can SN74ALS153D replace a 74LS153 in an existing design?

Yes, the SN74ALS153D is a direct logic-function replacement for the 74LS153 dual 4:1 multiplexer. The 74ALS family offers lower power consumption and higher speed than the original LS series, but the pinout and function are identical. Verify the supply voltage (4.5V-5.5V) and output drive (2.6 mA source / 24 mA sink) match your load requirements before swapping.
