Overview
The SN74AS32DB is a quadruple 2-input positive-OR gate manufactured by Texas Instruments. It belongs to the 74AS (Advanced Schottky) logic family and operates within a supply voltage range of 4.5V to 5.5V. The device features four independent OR gates, each with two inputs, housed in a 14-pin Small Outline Integrated Circuit (SOIC) package. Key electrical parameters include a maximum propagation delay of 5.8ns at 5V with a 50pF load, a high-level output current of 2mA, and a low-level output current of 20mA. Logic levels are defined as 0.8V for low and 2V for high. The component supports surface-mount installation and functions within an operating temperature range of 0°C to 70°C.
Feature Summary
- Implements quadruple 2-input positive-OR logic functionality
- Utilizes Advanced Schottky technology for high-speed operation
- Provides push-pull outputs with specified drive capabilities
Applications
- Digital logic circuit design requiring fast switching speeds
- Signal processing systems utilizing standard TTL-compatible voltages
- Industrial control applications operating within commercial temperature ranges
Procurement Notes
Verify the specific suffix 'DB' against official Texas Instruments documentation to confirm the exact package variant and tape-and-reel specifications. Confirm RoHS compliance status and lead-free designation through current manufacturer datasheets. Ensure the part number matches the required 14-SOIC dimensions and pinout configuration before procurement.
Selection Notes
Select this component when high-speed logic performance is required within the 74AS series constraints. Verify that the system operates strictly within the 4.5V to 5.5V supply voltage range. Ensure the application environment remains within the 0°C to 70°C commercial temperature limits. Confirm compatibility with existing PCB footprints for the 14-SOIC package.
Part Context
This component is part of the broader SN74AS32 family of quadruple 2-input OR gates. Variants such as SN74AS32D and SN74AS32DG4 share identical logical functionality but may differ in packaging details or environmental certifications. The SN74AS32DB specifically denotes the SOIC surface-mount package configuration within the Texas Instruments product line.
Replacement Considerations
Publicly confirmed substitute part numbers include SN74AS32D and SN74AS32DG4. These alternatives offer equivalent logical functionality and pinout compatibility. Verify package dimensions and thermal characteristics to ensure mechanical fit.
