Overview
The SN74ALS32DR is a quadruple 2-input positive-OR gate from the Texas Instruments ALS logic family. 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 propagation delay of 3 ns minimum to 14 ns maximum at VCC = 4.5 V to 5.5 V with CL = 50 pF. Electrical characteristics include a low-level output current (IOL) of up to 8 mA and a high-level output current (IOH) of -0.4 mA. It is housed in a 14-pin Small Outline Integrated Circuit (SOIC D) package.
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 power-speed performance
- Provides push-pull outputs capable of driving standard TTL loads
Applications
- General-purpose digital logic circuits requiring OR functionality
- Signal routing and selection in bus systems
- Data path control in microprocessor-based designs
Procurement Notes
Verify that the specific orderable part number matches the required package type, lead finish, and moisture sensitivity level. Confirm RoHS compliance status and ensure the component meets the intended operating temperature range specifications before integration into the final design.
Selection Notes
Select this component when designing with standard 5 V logic families requiring moderate speed and low power consumption. Ensure the application environment remains within the specified commercial temperature limits and that the load capacitance does not exceed the tested conditions to maintain guaranteed switching performance.
Part Context
This device belongs to the SN74ALS series, which represents an evolution of the standard 74S logic family. It offers improved power dissipation characteristics while maintaining comparable switching speeds. The 'D' suffix indicates the SOIC surface-mount package configuration, suitable for automated assembly processes.

FAQ
What is the Boolean function performed by the SN74ALS32DR?
The device performs the positive-OR function, where the output is high if either or both inputs are high (Y = A + B).
Does the SN74ALS32DR have tri-state outputs?
No, the SN74ALS32DR has standard push-pull outputs without an enable or tri-state control pin.
