What are the key features of SN74ALS32DRE4?
- Quad 2-input OR gate — 4 independent gates in a single 14-pin package
- ALS (Advanced Low-power Schottky) family for high-speed TTL-compatible logic
- 50 pF load capacitance for driving standard CMOS and TTL loads
- 8 mA maximum output sink current (I_OL) per gate
- JESD-609 e4 (RoHS-compliant) 14-pin SOIC package
- 5 V supply rail compatible with standard TTL/ALS logic ecosystems
What is SN74ALS32DRE4 used for?
The SN74ALS32DRE4 is used in digital signal routing, bus arbitration, and combinational logic circuits where multiple TTL-compatible logic signals must be OR-combined with minimal propagation delay. Its four independent 2-input gates allow compact implementations of address decoding, interrupt logic, and enable signal merging on single-board computers and industrial PLCs. The 14-pin SOIC package simplifies PCB layout for dense logic boards requiring multiple OR functions in a small area.

Frequently Asked Questions
Which design use cases are a practical fit for SN74ALS32DRE4?
SN74ALS32DRE4 is a Integrated Circuit from Texas Instruments suited to embedded systems, industrial electronics, communication equipment, test fixtures, and production BOM sourcing. The 14 pins detail helps engineers confirm schematic fit, interface allocation, and sourcing suitability before BOM approval.
How should engineers check package compatibility for SN74ALS32DRE4 during layout review?
Use the Small Outline Packages package information together with 14 pins when comparing footprints, assembly drawings, and mating or socket constraints. This reduces layout risk before prototype or production purchasing.
What should procurement keep aligned when cross-referencing SN74ALS32DRE4 against alternates?
Cross-reference checks should preserve the manufacturer, Integrated Circuit function, package style, lifecycle status, and at least one key parameter such as 74A. Matching these details lowers substitution risk across 1 approved BOM.
