74ALVC00D,118

Overview

The Nexperia 74ALVC00D,118 is a quad 2-input NAND gate in the ALVC logic family. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an operating temperature from -40 °C to +125 °C. The device features Schmitt trigger inputs for noise tolerance and IOFF circuitry for partial power-down protection. Propagation delay ranges from 1.0 ns to 5.1 ns depending on voltage and temperature. It is housed in a 14-lead SOIC (SOT108-1) package.

Feature Summary

• Schmitt trigger action on all inputs provides tolerance for slow rise and fall times.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.
• Overvoltage tolerant inputs allow direct interface with TTL levels.

Applications

• Mixed 3.3 V and 5 V environments
• Partial power-down applications
• General-purpose digital logic

Procurement Notes

Verify the specific ordering suffix matches the required package type. Confirm that the component meets the necessary JEDEC standards for the intended voltage range. Ensure the design accounts for the specified thermal derating characteristics above the maximum ambient temperature limits defined in the datasheet.

Selection Notes

Select this component when low power dissipation and high-speed operation are required. The wide supply voltage range accommodates various system architectures. Verify input transition rates against recommended operating conditions to ensure signal integrity and proper switching behavior.

Part Context

This part belongs to the 74ALVC series of CMOS logic gates. It shares functional similarities with other 74-series logic families but offers improved speed and lower power consumption. The 'D' designation indicates the SOIC package variant.

Replacement Considerations

Check for pin-compatible alternatives such as the 74LVC00 or 74AHC00 if voltage levels or drive strengths differ. Ensure any substitute maintains the required propagation delay and power-down capabilities.

FAQ

What is the function of the IOFF circuitry?

The IOFF circuitry disables the output when the device is powered down, preventing potentially damaging backflow current through the device.

Does the 74ALVC00 support partial power-down applications?

Yes, the device is fully specified for partial power-down applications using the IOFF feature.
