74ALVC00BQ,115

Overview

The 74ALVC00BQ,115 is a quad 2-input NAND gate manufactured by Nexperia. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes CMOS technology for low power dissipation. The device features Schmitt trigger inputs to tolerate slow rise and fall times. It includes I_OFF circuitry for partial power-down applications, preventing damaging backflow currents. The component is specified for operation from -40 °C to +85 °C and supports ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). It is housed in a 14-DHVQFN package.

Feature Summary

• Schmitt trigger action on all inputs provides tolerance for slow signal transitions.
• Integrated I_OFF circuitry enables safe partial power-down mode operation.
• Overvoltage tolerant inputs allow direct interfacing with TTL logic levels.

Applications

• Partial power-down systems requiring isolation during standby states
• Digital logic circuits interfacing between different voltage domains
• Signal conditioning for inputs with slow rise or fall times

Procurement Notes

Verify the specific suffix '115' corresponds to the DHVQFN-14 package configuration. Confirm compliance requirements such as RoHS and REACH status against current regulatory standards. Check for any Product Change Notifications (PCN) regarding material or assembly updates. Ensure the ordering part number matches the exact pinout and electrical specifications required for the design.

Selection Notes

Select this component when a quad NAND gate with Schmitt trigger inputs is required for noise immunity. It is suitable for designs needing direct TTL interface compatibility within the 1.65 V to 3.6 V supply range. Consider the I_OFF feature if the application involves partial power-down scenarios to prevent backflow currents. Verify that the 14-DHVQFN package fits the available PCB footprint constraints.

Part Context

This part belongs to the 74ALVC family of high-speed CMOS logic devices. It is designed for low-voltage applications and offers improved performance over standard LV logic families. The device is compliant with JEDEC standards for various voltage ranges, ensuring interoperability with other industry-standard logic components.

Replacement Considerations

Direct substitutes include other 74ALVC00 variants from Nexperia or equivalent quad NAND gates from other manufacturers that match the 1.65 V–3.6 V operating range and DHVQFN-14 package. Verify pin compatibility and electrical characteristics before substitution.
