74AXP1T57DC-Q100H

Overview

The Nexperia 74AXP1T57DC-Q100H is a dual supply configurable multiple function gate with Schmitt-trigger inputs, housed in an SOT765-1 (VSSOP8) package. It features three inputs (A, B, C) and one output (Y), with separate VCCI and VCCO supply pins. The input voltage range is 0.7 V to 2.75 V, while the output voltage range is 1.2 V to 5.5 V. It supports logic functions including AND, OR, NAND, NOR, XNOR, inverter, and buffer. Qualified to AEC-Q100 Grade 1, it operates from -40 °C to +125 °C.

Feature Summary

• Configurable as multiple logic functions including AND, OR, NAND, NOR, XNOR, inverter, and buffer
• Dual supply architecture enabling voltage level translation between independent input and output domains
• IOFF circuitry prevents backflow current during partial power-down applications
• Automotive qualification compliant with AEC-Q100 Grade 1 standards

Applications

• Voltage level translation between different logic families
• Automotive electronic systems requiring AEC-Q100 compliance
• Partial power-down mode operation in battery-powered devices
• Logic function configuration in space-constrained designs

Procurement Notes

Verify the specific ordering suffix DC-Q100H corresponds to the VSSOP8 package and automotive grade requirements. Confirm that the component meets the required temperature range of -40 °C to +125 °C for your application environment. Ensure compatibility with the specified supply voltage ranges for both input and output domains before finalizing procurement.

Selection Notes

Select this component when a single gate must perform multiple logic functions or translate voltages between 0.7 V–2.75 V and 1.2 V–5.5 V domains. It is suitable for automotive applications due to its AEC-Q100 Grade 1 qualification. Consider the VSSOP8 package size if board space is limited. Verify that the IOFF feature is necessary for managing power-down states in your system design.

Part Context

This device belongs to the 74AXP family of Si-Gate CMOS devices designed for low power consumption and high noise immunity. The 74AXP1T57-Q100 variant specifically targets automotive applications, offering configurable logic functions within a compact VSSOP8 package. It integrates Schmitt-trigger inputs for improved signal integrity and supports partial power-down modes via dedicated IOFF circuitry.

Replacement Considerations

Check for direct substitutes within the 74AXP1T57 series that match the Q100 automotive qualification and VSSOP8 packaging. Verify pinout compatibility and electrical specifications, particularly the dual supply voltage ranges and logic function configurations, before replacing.
