Overview
The SN74ALS32NSR is a quadruple 2-input positive-OR gate from the Texas Instruments ALS logic family, housed in a 14-pin Small Outline Package (SOP). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features a low-level output current capability of 8 mA and a high-level output current of -0.4 mA. Propagation delays are specified with a maximum of 14 ns for tPLH and 12 ns for tPHL under standard load conditions.
Feature Summary
- Contains four independent 2-input OR gates performing Boolean functions Y = A + B
- Compatible with standard TTL input levels and CMOS output drive capabilities
- Designed for surface-mount assembly using the 14-pin SOP package
Applications
- Digital logic circuit design requiring OR functionality
- Signal routing and selection in bus systems
- General-purpose logic processing in industrial control equipment
Procurement Notes
Verify that the ordering suffix 'SR' corresponds to the Large Tape & Reel packaging configuration as documented in the official TI Package Option Addendum. Confirm the specific lead finish and moisture sensitivity level ratings match the requirements for the intended manufacturing process before finalizing procurement orders.
Selection Notes
Select this component when a quad 2-input OR function is required in a surface-mount application. Ensure the system design accommodates the 4.5 V to 5.5 V supply voltage range and the 0°C to 70°C commercial temperature limits. Verify that the propagation delay characteristics meet the timing constraints of the target digital interface.
Part Context
This part belongs to the SN74ALS32 series, which provides high-speed logic operations within the Advanced Low-Power Schottky family. The device serves as a standard catalog product for general-purpose logic applications, distinct from the military-grade SN54 variants which support extended temperature ranges.
Replacement Considerations
SN74ALS32DR is a parameter-equivalent alternative available in the SOIC D package.
