Overview
The SN74AHC02PWRE4 is a quadruple 2-input positive-NOR gate from the Texas Instruments AHC logic family, housed in a 14-pin TSSOP package. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to +125°C. The device provides low-level output currents up to 8mA and high-level output currents down to -8mA at 5V operation. Switching characteristics include propagation delays of approximately 6.5ns maximum at 5V with 15pF load capacitance.
Feature Summary
- Contains four independent 2-input NOR gates performing Boolean function Y = A + B
- Latch-up performance exceeds 250mA per JESD 17 standard
- Supports wide supply voltage operation from 2V to 5.5V
- Compatible with standard CMOS logic levels across the operating voltage range
Applications
- General-purpose digital logic signal processing
- Boolean logic implementation in embedded systems
- Signal gating and control circuits
- Interface logic for mixed-voltage digital environments
Procurement Notes
Verify the specific ordering suffix 'E4' corresponds to lead-free and RoHS compliance requirements as defined by Texas Instruments. Confirm the PW package designation matches the required TSSOP-14 footprint for PCB layout. Ensure the component status is checked against current production data sheets, as availability may vary based on manufacturing lifecycle updates.
Selection Notes
Select this component when a quad NOR gate configuration is required within the AHC speed and power envelope. The TSSOP-14 package offers a compact surface-mount solution suitable for space-constrained designs. Consider the -40°C to +125°C temperature range for industrial applications requiring extended thermal stability compared to commercial-grade alternatives.
Part Context
This part belongs to the SNx4AHC02 family of quadruple 2-input positive-NOR gates manufactured by Texas Instruments. The 'SN' prefix indicates a commercial grade device, while 'AHC' denotes the advanced high-speed CMOS technology. The 'PW' suffix specifies the plastic small-outline (TSSOP) package type, and 'E4' typically signifies environmental compliance features such as lead-free termination.
Replacement Considerations
Direct pin-compatible replacements within the same family include SN74AHC02PWR or SN74AHC02DR. For broader compatibility, verify electrical specifications against other SN74AHC02 variants. Cross-referencing with SN54AHC02 requires attention to military-grade temperature ranges and packaging differences.
