Key Features
- Four independent 2-input OR gates in a single 14-pin SOIC package maximizes logic density and simplifies PCB routing in digital designs
- Standard 74LS TTL family with 4.75 V to 5.25 V supply range ensures broad compatibility with legacy and new 5 V digital systems
- Low-power Schottky (LS) technology balances speed and power consumption, offering faster switching than standard TTL at reduced quiescent current
- TTL-compatible input and output thresholds enable direct interfacing with other 74LS, 74S, and 74HCT logic family devices
- 14-pin SOIC plastic/epoxy package is industry-standard and supported by virtually every PCB layout and assembly toolchain
Applications
The SN74LS32D is used throughout digital logic circuits for signal combining, interrupt aggregation, enable logic, and combinational logic functions in microcontroller-based systems and legacy 5 V TTL designs. It is a fundamental building block in address decoding, bus arbitration, and event detection circuits where two or more conditions must trigger a single output. The device is also found in educational electronics kits, prototyping boards, and production logic circuits requiring small, reliable, and low-cost OR gate functions.

Frequently Asked Questions
How many gates are in the SN74LS32D and what is their logic function?
The SN74LS32D contains four independent 2-input OR gates. Each gate produces a logic HIGH output when one or both inputs are HIGH, and a logic LOW output only when both inputs are LOW. The four gates operate independently and can be used together or separately within the same IC.
What supply voltage does the SN74LS32D require?
The SN74LS32D operates from a 5 V supply with a tolerance range of 4.75 V to 5.25 V, conforming to standard TTL LS family specifications. This makes it directly compatible with 5 V microcontroller systems, CMOS logic running at 5 V, and a wide range of legacy TTL digital designs.
What package does the SN74LS32D use?
The SN74LS32D comes in a 14-pin SOIC (Small Outline Integrated Circuit) package with a 1.27 mm pin pitch and plastic/epoxy body construction. This industry-standard surface-mount package is compatible with most EDA footprint libraries and is suitable for reflow soldering in both prototype and high-volume production.
Is the SN74LS32D RoHS compliant and lead-free?
Yes, the SN74LS32D carries a JESD-609 code of 'e4' indicating it is manufactured with lead-free, RoHS-compliant materials. It meets European Union RoHS Directive requirements and is suitable for use in consumer electronics, industrial equipment, and other applications where environmental compliance is mandated.
What are common replacements or equivalent parts for the SN74LS32D?
Pin-compatible alternatives include the 74LS32 from NXP Semiconductors, ON Semiconductor, and Fairchild (now onsemi). Higher-performance equivalents in different logic families include the SN74HCT32 (5 V CMOS, higher speed) and SN74HC32 (2 V to 6 V CMOS). Users should verify timing parameters, input thresholds, and drive strength when switching logic families.
