74LV1T02GVH

Inverter Gates Overview

The Nexperia 74LV1T02GVH is a single, level translating 2-input NOR gate housed in an SC-74A (SOT753) package. It operates with a supply voltage range of 1.6 V to 5.5 V and supports input voltages up to 5.5 V. The device facilitates both up translation (e.g., 1.8 V to 3.3 V) and down translation (e.g., 3.3 V to 1.8 V). Propagation delay ranges from 4.7 ns at 5.0 V with 30 pF load to 12.2 ns at 1.8 V with 15 pF load. Operating temperature spans -40 °C to +125 °C.

Inverter Gates Feature Summary

• Supports bidirectional voltage level translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V CMOS levels using a single supply.
• Features low threshold inputs that enable 1.8 V logic compatibility at 3.3 V supply and 5 V tolerant inputs for interfacing with higher voltage systems.
• Includes Ioff circuitry to disable outputs during partial power-down, preventing damaging backflow currents.

Inverter Gates Applications

• Portable applications
• PC and notebooks
• Industrial controllers
• Telecom equipment

Inverter Gates Procurement Notes

Verify the specific suffix GVH corresponds to the SC-74A (SOT753) package variant as documented in the ordering information table. Confirm the required operating temperature range matches the -40 °C to +125 °C specification provided for this package type. Ensure design compliance with the absolute maximum ratings regarding supply voltage and input clamping currents to prevent permanent damage.

Inverter Gates Selection Notes

Select this component when a single-supply NOR gate with bidirectional level shifting capabilities is required. It is suitable for mixed-voltage environments where signals must be translated between 1.8 V, 2.5 V, 3.3 V, and 5.0 V domains. The SC-74A package offers a compact surface-mount solution for space-constrained designs requiring high noise immunity and ESD protection.

Inverter Gates Part Context

The 74LV1T02 belongs to the LV (Low-Voltage CMOS) logic family, optimized for low voltage applications ranging from 1.0 V to 3.6 V, though this specific translator variant extends operational limits. The 'GV' designation indicates the SC-74A plastic surface-mounted package with five leads. This series is designed for general-purpose digital logic applications requiring reliable signal translation across different voltage standards.

Inverter Gates Replacement Considerations

Check for equivalent parts within the same logic family or other manufacturers offering similar single-supply translating NOR gates in the SC-74A package. Verify pinout compatibility and electrical specifications such as propagation delay and supply voltage range before substitution.

Inverter Gates FAQ

Can the 74LV1T02GVH translate signals from 3.3 V to 1.8 V?

Yes, the device supports down translation, specifically converting 3.3 V inputs to 1.8 V outputs when powered by a 1.8 V supply.

What is the function of the Ioff circuitry in this device?

The Ioff circuitry disables the output when the device is in a partial power-down state, preventing potentially damaging backflow current through the device.
