SN74HCT02NG4

Inverter Gates Overview

The SN74HCT02NG4 is a quadruple 2-input positive-NOR gate manufactured by Texas Instruments. It belongs to the SN74HCT 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 maximum low-level output current of 4 mA and a high-level output current of -4 mA. It features a propagation delay of 10 ns and functions reliably across an operating temperature range from -40 °C to +85 °C.

Inverter Gates Feature Summary

• Provides four independent 2-input NOR logic gates in a single package
• Features TTL-compatible input thresholds for direct interfacing with TTL logic systems
• Delivers standard push-pull outputs capable of driving moderate loads

Inverter Gates Applications

• Digital logic circuit design requiring NOR functionality
• Signal processing within microcontroller peripheral interfaces
• General-purpose logic control in industrial instrumentation

Inverter Gates Procurement Notes

Verify the specific suffix 'G4' indicates lead-free construction and RoHS compliance when sourcing. Confirm the package type matches the required PCB footprint, as this part number typically corresponds to the PDIP-14 through-hole configuration. Ensure the supply voltage remains strictly within the 4.5 V to 5.5 V limits to maintain signal integrity and prevent device damage.

Inverter Gates Selection Notes

Select this component when TTL-compatible inputs are necessary alongside CMOS power efficiency. It serves as a suitable alternative to older 74LS series parts where lower power consumption is desired without sacrificing noise immunity. Consider the PDIP-14 package if prototyping or manual assembly is required rather than surface-mount technologies.

Inverter Gates Part Context

This component is part of the broader SN74HCT family, which bridges the gap between legacy TTL logic standards and modern CMOS manufacturing processes. The HCT designation specifically ensures that input voltage levels match traditional TTL requirements, allowing seamless integration into existing digital designs while benefiting from improved power characteristics compared to bipolar counterparts.

Inverter Gates Replacement Considerations

Direct functional equivalents include the SN74HCT02N and SN74HCT02DR. Verify pinout compatibility before substitution. Other variants such as SN74HC02 offer similar logic but lack TTL-compatible input thresholds.
