SN74LV4T00QPWRQ1

Inverter Gates Overview

The SN74LV4T00QPWRQ1 is an automotive-grade quadruple 2-input positive-NAND gate with integrated voltage translation. It operates on a single supply voltage ranging from 1.6 V to 5.5 V and supports standard CMOS logic levels including 1.8 V, 2.5 V, 3.3 V, and 5 V. The device features Schmitt-trigger inputs for noise immunity and balanced CMOS outputs capable of driving up to ±15 mA at 3.3 V or 5.0 V. It provides up-translation from lower voltages (e.g., 1.2 V) and down-translation from higher voltages (up to 5.5 V tolerant inputs). The component meets AEC-Q100 Grade 1 standards for operation between -40°C and +125°C.

Inverter Gates Feature Summary

• Integrated voltage level translation supporting both up-conversion and down-conversion across multiple CMOS logic families
• Automotive qualification compliant with AEC-Q100 standards for high reliability in vehicle environments
• Schmitt-trigger inputs provide enhanced noise filtering and tolerance for slow input transition rates
• Wettable flank package design facilitates reliable soldering and enables effective automatic optical inspection

Inverter Gates Applications

• Translation between communication modules and system controllers
• Enabling or disabling digital signals within automotive circuits
• Controlling indicator LEDs via active-low latch configurations

Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required package type, as the SN74LV4T00-Q1 family includes distinct variants such as WBQA and PW. Confirm that the selected part number aligns with the intended thermal and mechanical constraints for the target PCB layout. Ensure compliance with the specified operating temperature range and voltage requirements before finalizing procurement.

Inverter Gates Selection Notes

Select this component when interfacing logic circuits operating at different voltage levels within a single power domain. The integrated translation eliminates the need for external level shifters. Consider the Schmitt-trigger inputs if the signal source exhibits slow rise or fall times. Verify that the output current requirements do not exceed the device's maximum ratings to prevent damage.

Inverter Gates Part Context

This device belongs to the SN74LV4T00-Q1 series, which is part of Texas Instruments' LVxT family of logic devices designed for low-voltage applications. The series integrates voltage translation capabilities directly into standard NAND gate functionality. The Q1 suffix indicates automotive qualification, distinguishing it from commercial grade counterparts while maintaining similar electrical performance characteristics.

Inverter Gates Replacement Considerations

Direct replacements include other SN74LV4T00-Q1 variants with different package options, such as SN74LV4T00PWREP or SN74LV4T00WBQARQ1. Ensure the substitute maintains the same logic function and voltage translation specifications.
