Overview
The SN74ALS32DE4 is a quadruple 2-input positive-OR gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range of 0°C to 70°C. The device features low-level output currents up to 8 mA and high-level output currents up to -0.4 mA. Propagation delays are specified with maximum values of 14 ns for tPLH and 12 ns for tPHL under standard load conditions.
Feature Summary
- Contains four independent 2-input positive-OR gates performing Boolean functions Y = A + B
- Utilizes Advanced Low-Power Schottky (ALS) technology for optimized performance
- Provides standardized logic levels compatible with TTL systems
Applications
- Boolean logic implementation in digital circuits
- Signal routing and selection networks
- General-purpose logic processing in industrial control systems
Procurement Notes
Verify the specific ordering suffix against current manufacturer documentation, as package availability and status may vary. Confirm RoHS compliance and lead finish specifications directly from the official datasheet or packaging addendum before procurement to ensure compatibility with assembly processes.
Selection Notes
Select this component when designing circuits requiring multiple OR logic functions within a single integrated circuit. Ensure the application environment remains within the specified 0°C to 70°C temperature range and that the power supply voltage stays between 4.5 V and 5.5 V for reliable operation.
Part Context
This part belongs to the SN74ALS32 family of quadruple 2-input positive-OR gates produced by Texas Instruments. It is designed for commercial applications and is distinct from the military-grade SN54 series variants which support extended temperature ranges. The device is available in various packages including SOIC and PDIP.
Replacement Considerations
Compatible substitutes include other SN74ALS32 variants such as SN74ALS32DR or SN74ALS32N, provided the package type matches the design requirements. Verify pinout compatibility and electrical characteristics against the original specification.
