MC74HC1G02DTT1 Description

The MC74HC1G02DTT1 from onsemi is a high-performance single 2-input NOR gate IC belonging to the 74HC series, designed for surface-mount applications. Operating within a 2V to 6V supply range, it delivers low-power CMOS logic with a maximum propagation delay of 17ns at 6V and 50pF load, ensuring efficient signal processing. This 5-pin TSOP-packaged device is optimized for compact designs, featuring low quiescent current (1 µA max) and symmetrical output drive (2.6mA sink/source). Although marked as obsolete, it remains relevant in legacy systems due to its REACH compliance and unlimited moisture sensitivity (MSL 1).

MC74HC1G02DTT1 Features

• Logic Type: Single 2-input NOR gate with HC-series speed/power balance.
• Wide Voltage Range: 2V–6V operation, compatible with TTL levels.
• Low Power: 1 µA max quiescent current ideal for battery-powered devices.
• High Noise Immunity: Input thresholds of 1.5V–4.2V (High) and 0.5V–1.8V (Low).
• Robust Output: 2.6mA balanced output current for driving moderate loads.
• Packaging: Tape & Reel (TR) 5-TSOP, suited for automated assembly.
• Environmental Compliance: EAR99 and REACH Unaffected, ensuring global usability.

MC74HC1G02DTT1 Applications

• Portable Electronics: Low quiescent current makes it ideal for wearables and IoT sensors.
• Signal Conditioning: Used in debouncing circuits and clock gating due to fast propagation.
• Industrial Control: Reliable performance in PLC I/O modules and logic level shifting.
• Legacy System Maintenance: Replacing older NOR gates in automotive or telecom infrastructure.
• Space-Constrained Designs: TSOP package fits densely populated PCBs in medical devices.

Conclusion of MC74HC1G02DTT1

The MC74HC1G02DTT1 offers a cost-effective, space-saving solution for NOR-based logic needs, balancing speed, power efficiency, and noise immunity. While obsolete, its standardized HC-series performance and surface-mount compatibility ensure continued utility in low-power and compact applications. Engineers should evaluate alternatives for new designs but can leverage this IC for retrofits or niche requirements.
