Overview
The SN74AHCT32DRG4 is a quadruple 2-input positive-OR gate from the Texas Instruments 74AHCT logic family. It operates within a supply voltage range of 4.5V to 5.5V, ensuring compatibility with standard 5V CMOS systems while accepting TTL-compatible inputs. The device features four independent OR gates in a single package, housed in a 14-pin Small Outline Integrated Circuit (SOIC) surface-mount package. It supports an operating temperature range from -40°C to +85°C and includes low static current characteristics typical of advanced high-speed CMOS technology.
Feature Summary
- Integrates four independent 2-input OR logic functions within a compact SOIC-14 package
- Provides TTL-compatible input thresholds for seamless interfacing with legacy digital systems
- Delivers high-speed switching performance suitable for complex digital signal processing applications
Applications
- Digital logic circuit design requiring multiple OR operations
- Signal routing and selection in communication equipment
- Data acquisition systems utilizing 5V logic interfaces
Procurement Notes
Verify the complete part number including the suffix 'G4' to confirm lead-free and RoHS compliance status as specified by Texas Instruments. Ensure the ordering information matches the specific package variant and temperature grade required for your application environment. Cross-reference official datasheets for any recent product change notifications or lifecycle status updates before finalizing procurement plans.
Selection Notes
Select this component when designing circuits that require multiple OR gates with TTL-compatible input levels in a 5V system. The AHCT series offers a balance of speed and power consumption compared to older HC or HCT families. Consider the SOIC-14 package dimensions for PCB layout constraints and verify thermal requirements for the intended operating temperature range.
Part Context
This component belongs to the Texas Instruments 74AHCT series, which bridges the gap between high-speed Advanced High-CMOS (AHC) performance and TTL-compatible input levels. The '32' designation specifically identifies it as containing four 2-input OR gates. The 'DRG4' suffix indicates the SOIC-14 package type and lead-free/RoHS compliant manufacturing process.
Replacement Considerations
Direct functional equivalents include the SN74AHCT32DRE4 and SN74AHCT32DR. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
