Genuine 74LS32 Quad 2-Input OR Gate – Essential TTL Logic for Restoration
Versatile Logic for Classic Hardware
The 74LS32 is an integrated circuit containing four independent 2-input OR gates. In the context of retro computing, these gates are often used for address decoding, signal buffering, and peripheral interfacing. Because the “LS” (Low-power Schottky) series was the industry standard during the 1980s, these chips are the perfect, period-accurate choice for repairing vintage motherboards without causing the timing issues sometimes associated with modern “HC” or “HCT” CMOS variants.
Reliability for Professional Repairs
Whether you are fixing a “dead” arcade PCB or restoring a home computer, component quality is paramount. Our 74LS32 ICs are sourced to ensure high-grade construction and reliable logic thresholds. The 14-pin Dual In-Line (DIL) package makes them easy to solder directly to a PCB or insert into a standard IC socket.
Key Technical Specifications:
- Logic Type: Quad 2-Input OR Gate.
- Logic Family: 74LS (Low-power Schottky).
- Package Type: 14-pin DIL / DIP (Dual In-Line).
- Operating Voltage: Standard 5V TTL.
- Compatibility: Direct replacement for 7432, 74LS32, and 74HCT32 in most vintage computing applications.
Common Applications:
- Sinclair ZX Spectrum: Often used in various logic steering and glue-logic roles.
- Commodore 64 / 128: Used in address decoding and signal management.
- Arcade Boards: Found across hundreds of classic JAMMA and pre-JAMMA PCBs.
Educational Projects: An ideal chip for teaching basic Boolean logic on breadboards.
