Frequently Asked Questions
What is the SN74ALS151D and what does it do?
The SN74ALS151D is a single 8-to-1 data multiplexer IC from Texas Instruments. It selects one of eight data inputs (D0–D7) based on three binary select lines (A, B, C) and routes it to the output. It features complementary outputs Y and W, an active-low strobe input, and operates from a 5V supply in a 16-pin SOIC package.
What are the key electrical specifications of the SN74ALS151D?
The SN74ALS151D operates on a 5V VCC supply, features a maximum output sink current (I_OL) of 24mA, a load capacitance (CL) of 50pF, and belongs to the Advanced Low-power Schottky (ALS) logic family. It is housed in a 16-pin SOIC (R-PDSO-G16) package and is RoHS-compliant (JESD-609 Code e4).
What are typical applications for the SN74ALS151D?
The SN74ALS151D is commonly used in data routing, signal multiplexing, address decoding, and parallel-to-serial data conversion. It suits microprocessor bus systems, industrial PLCs, test equipment, and communication hardware where selecting one of multiple input signals is required.
What packages and alternatives are available for the SN74ALS151D?
The SN74ALS151D is available in a 16-pin SOIC (Small Outline IC) surface-mount package. Compatible alternatives include the SN74LS151 (LS logic family, DIP or SOIC), SN74HCT151 (high-speed CMOS, 5V), and SN74ALS151N (same ALS family in DIP-16). Always verify supply voltage and timing compatibility when substituting.
