74HCT2G02DP,125

Inverter Gates Overview

The Nexperia 74HCT2G02DP,125 is a dual 2-input NOR gate from the 74HCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels for direct interfacing with Transistor-Transistor Logic systems. The device is housed in an SOT505-2 TSSOP8 package with eight leads. Key electrical parameters include a propagation delay of up to 29 ns at 4.5 V and low-level output current capability of 5.2 mA. It supports an operating temperature range from -40 °C to +125 °C.

Inverter Gates Feature Summary

• Features reduced input threshold levels specifically designed to allow direct interfacing with TTL logic levels.
• Includes input clamp diodes that enable the use of current limiting resistors for interfacing inputs to voltages exceeding VCC.
• Provides high noise immunity and CMOS low power dissipation characteristics.

Inverter Gates Applications

• Interfacing between TTL logic sources and CMOS NOR gate circuits
• Digital signal processing requiring dual 2-input NOR functionality
• General-purpose logic applications in industrial environments

Inverter Gates Selection Notes

Select this component when TTL-compatible NOR logic is required in a compact surface-mount form factor. The HCT series ensures compatibility with standard 5V TTL logic families. Ensure the design accommodates the specified 4.5 V to 5.5 V supply voltage range and the thermal derating requirements for the TSSOP8 package above 96 °C.

Inverter Gates Part Context

This part belongs to the Nexperia 74HCT family of high-speed Si-gate CMOS devices. The 'DP' designation indicates the TSSOP8 plastic thin shrink small outline package (SOT505-2). The ',125' suffix typically denotes tape and reel packaging, though verification against official documentation is recommended as suffix meanings can vary by distributor or region.

Inverter Gates Replacement Considerations

The 74HC2G02DP,125 serves as a CMOS-level compatible alternative but requires level shifting for TTL interfaces. Other packages such as the VSSOP8 (74HCT2G02DC) offer space-saving options with identical logical functions.

Inverter Gates FAQ

What is the function of the input clamp diodes?

The input clamp diodes allow the use of current limiting resistors to interface inputs to voltages in excess of VCC without damaging the device.

How does the 74HCT2G02 differ from the 74HC2G02 regarding input levels?

The 74HCT2G02 features reduced input threshold levels to allow direct interfacing to TTL logic levels, whereas the 74HC2G02 uses CMOS input levels.
