SN74HC02NSRG4

Overview

The SN74HC02NSRG4 is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the HC logic series and operates within a supply voltage range of 2 V to 6 V. The device features four independent NOR gates, each with two inputs, providing a total of eight input lines and four output lines. Key electrical parameters include a low-level output current of 5.2 mA and a high-level output current of -5.2 mA. The propagation delay is specified at 18 ns under standard conditions. It supports an operating temperature range from -40 °C to +125 °C and is housed in a TSSOP-14 package.

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and manufacturing details as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the order quantity aligns with available packaging options such as tape and reel or cut tape. Cross-reference the manufacturer part number with official distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a quadruple 2-input NOR function is required in a compact surface-mount package. It is suitable for designs needing operation at lower voltages down to 2 V or extended temperature ranges. Compare against standard SN74HC02 variants if automotive qualification or specific environmental certifications are mandatory for the target application.

Part Context

This part is a member of the SNx4HC02 family of quadruple 2-input positive-NOR gates. It shares functional compatibility with other devices in the 74HC series while offering specific packaging and compliance attributes defined by the suffix. The device serves as a fundamental building block for complex digital logic designs requiring NOR functionality.
