SN74HCT02D

Inverter Gates Overview

The SN74HCT02D is a quadruple 2-input positive-NOR gate from the Texas Instruments SN74HCT02 series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 10 ns. The device provides a low-level output current of 4 mA and a high-level output current of -4 mA. It is housed in a 14-pin SOIC package and supports surface-mount installation. The component functions reliably across an operating temperature range of -40 °C to +85 °C.

Inverter Gates Feature Summary

• Contains four independent 2-input NOR logic gates
• Compatible with standard CMOS logic outputs
• Operates at a fixed 5 V supply voltage

Inverter Gates Applications

• Digital signal processing circuits
• General-purpose logic control systems
• Embedded system input/output interfacing

Inverter Gates Procurement Notes

Verify that the specific part number matches the required SN74HCT02D designation, as suffixes may indicate different packaging or temperature ratings. Confirm the manufacturer is Texas Instruments to ensure compliance with specified electrical characteristics. Check for RoHS compliance status if environmental regulations apply to the intended deployment environment.

Inverter Gates Selection Notes

Select this component when a quadruple 2-input NOR function is required in a 5 V digital system. The HCT series ensures compatibility with TTL inputs while maintaining CMOS noise immunity. Consider the SOIC-14 package dimensions for PCB layout constraints. Ensure the application operates within the specified -40 °C to +85 °C temperature range for optimal performance.

Inverter Gates Part Context

This device belongs to the SN74HCT02 family of single-function logic gates. It shares the same logical functionality as other variants in the series but differs in physical packaging and thermal specifications. The HCT technology allows direct interface with TTL devices, making it suitable for mixed-logic environments requiring reliable NOR operations.

Inverter Gates Replacement Considerations

SN74HCT02DR: Same functional logic and electrical parameters; differs only in tape-and-reel packaging format instead of tube.
