Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required package type, as variations exist within the product line. Confirm compliance with AEC-Q100 requirements if automotive qualification is necessary for the intended application environment. Ensure that unused inputs are tied to either VCC or GND to maintain normal operation and prevent undefined states.

Inverter Gates Selection Notes

Select this component when a quad NOR gate configuration is required with wide voltage tolerance and extended temperature capability. The balanced propagation delays make it suitable for timing-critical applications. Consider the TSSOP-14B package constraints regarding thermal derating factors above 85 °C to ensure reliable power dissipation under heavy load conditions.

Inverter Gates Part Context

This device belongs to the 74VHC series of advanced high-speed CMOS logic integrated circuits manufactured by Toshiba Semiconductor and Storage.

Inverter Gates Replacement Considerations

The datasheet notes pin and function compatibility with other 74 series types such as AC, HC, AHC, and LV variants of the 02 type. Verify electrical characteristics and voltage ranges when substituting with these compatible families to ensure system integrity.

Inverter Gates FAQ

Can the 74VHC02FT interface 5 V systems with 3 V systems?

Yes, the internal input protection circuit allows 0 to 5.5 V to be applied to the input pins without regard to the supply voltage, enabling safe interfacing between 5 V and 3 V systems.

What is the maximum quiescent supply current?

The maximum quiescent supply current (ICC) is 2.0 µA at Ta = 25 °C. This value increases to 40.0 µA maximum at temperatures ranging from -40 °C to 125 °C.
