SN74LVC2G38DCUTE4

Inverter Gates Overview

The SN74LVC2G38DCUTE4 is a dual two-input NAND gate with open-drain outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and supports 5-V VCC operation. The device features Ioff circuitry for partial-power-down mode, preventing damaging current backflow when powered down. Inputs accept voltages up to 5.5 V, ensuring compatibility with various logic families. Latch-up performance exceeds 100 mA per JESD 78, Class II standards. Maximum propagation delay is 4 ns at 3.3 V. Low power consumption is characterized by a maximum ICC of 10 μA. ESD protection exceeds ±2000 V (Human-Body Model), ±200 V (Machine Model), and -1000 V (Charged-Device Model).

Inverter Gates Feature Summary

• Dual two-input NAND gate configuration with open-drain outputs.
• Ioff circuitry enables partial-power-down mode to prevent backflow currents.
• Inputs tolerate voltages up to 5.5 V while operating on lower supply rails.
• High latch-up immunity exceeding 100 mA per JESD 78, Class II.

Inverter Gates Applications

• Partial-power-down applications requiring output disabling.
• Mixed-voltage logic interfacing between different supply domains.
• Open-drain bus configurations requiring pull-up resistors.

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'E4' indicates lead-free status and RoHS compliance as defined in the Package Option Addendum. Confirm the DCU package type matches the required PCB footprint. Ensure the temperature range (-40°C to 85°C) aligns with system environmental specifications. Cross-reference the datasheet revision date against manufacturing lot dates for production validity.

Inverter Gates Selection Notes

Select this component when an open-drain NAND function is required for mixed-voltage systems. The 5.5 V input tolerance allows direct interfacing with 5 V logic without level shifting. The low static current makes it suitable for battery-powered or energy-efficient designs. Verify that the open-drain nature meets the load requirements, as high-level output voltage depends on external pull-up components.

Inverter Gates Part Context

This part belongs to the SN74LVC2G38 family of dual NAND gates. The 'DCU' suffix denotes the VSSOP-8 surface-mount package. The 'E4' suffix typically signifies lead-free and RoHS-compliant manufacturing processes. It is designed for portable and space-constrained applications due to its small form factor and low power characteristics.

Inverter Gates Replacement Considerations

SN74LVC2G38DCUR: Identical electrical specifications and functionality; differs only in reel quantity (3000 vs 250 units). SN74LVC2G38DCTR: Same logic function but utilizes the DCT SSOP-8 package instead of VSSOP-8. SN74LVC2G38YZPR: Same logic function but utilizes the YZP NanoFree WSP package.
