Overview
The SN74AHCT02PW is a quadruple 2-input positive NOR gate manufactured by Texas Instruments. It belongs to the SN74AHCT logic series, utilizing CMOS technology with TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -40°C to +85°C. Packaged in a 14-pin TSSOP surface-mount case, it features three-state outputs for effective bus-driven applications.
Feature Summary
- Provides four independent 2-input NOR logic functions
- Features TTL-compatible input thresholds for direct interfacing with TTL signals
- Supports high-speed operation with low propagation delay characteristics
- Offers three-state output capability for efficient bus system management
Applications
- General-purpose digital logic circuits requiring NOR functionality
- Bus-oriented systems utilizing three-state control
- Consumer electronics employing 5V logic families
- Industrial control systems operating within standard temperature ranges
Procurement Notes
Verify the specific package variant, as SN74AHCT02PW denotes the TSSOP-14 configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure design compatibility with 5V power domains due to the AHCT series voltage constraints. Check for end-of-life notices or alternative recommendations if long-term supply stability is required.
Selection Notes
Select this component when a quadruple 2-input NOR gate is required with TTL-compatible input levels. The AHCT series is suitable for designs needing fast switching speeds while maintaining compatibility with legacy TTL logic families. The TSSOP-14 package offers a compact solution for space-constrained printed circuit board layouts compared to traditional DIP packages.
Part Context
This part is a member of the Texas Instruments SN74AHCT family, which combines the high speed of advanced CMOS technology with the noise margins and input compatibility of standard TTL logic. The '02' suffix identifies the specific NOR gate function within the broader 74-series logic catalog, distinguishing it from NAND, AND, or buffer variants.
Replacement Considerations
Direct pin-to-pin replacements include SN74AHCT02DR (SOIC-14) and SN74AHCT02N (DIP-14). Verify that substitute packages match the physical footprint requirements of the existing design.
