Nexperia USA Inc. 74AXP1T57GXX

Overview

74AXP1T57 from Nexperia is a dual-supply configurable logic gate with Schmitt-trigger inputs, three inputs (A/B/C), one output (Y), and independent input/output supply rails (VCCI: 0.7–2.75 V; VCCO: 1.2–5.5 V). It supports seven logic functions (AND, OR, NAND, NOR, XNOR, inverter, buffer) via pin-strapping and enables bidirectional voltage level translation in low-power I/O interfaces.

For engineers reviewing the 74AXP1T57 datasheet, 74AXP1T57 pinout, 74AXP1T57 application, or 74AXP1T57 equivalent, this device is selected for mixed-voltage system interfacing where static/dynamic power minimization, IOFF-enabled partial power-down, and Schmitt-trigger noise immunity are critical design requirements.

Technical Context

The 74AXP1T57 implements a single configurable gate using CMOS technology with Schmitt-trigger inputs referenced to VCCI and an output stage referenced to VCCO. Its function selection is determined by the logic states applied to A, B, and C - no external configuration register or control bus is used.

It features IOFF circuitry that disables the output and blocks backflow current when either supply is at 0 V, enabling safe operation during power sequencing. Input hysteresis (VH = 0.2–1.0 V) and wide operating temperature (−40 °C to +125 °C) support robust performance in industrial and automotive edge nodes.

Key Specifications

FAQ

What logic functions can the 74AXP1T57 implement, and how is configuration performed?

The 74AXP1T57 implements AND, OR, NAND, NOR, XNOR, inverter, and buffer functions. Configuration is achieved by hardwiring inputs A, B, and C to VCCI or GND - no programming interface or external clock is required. The function is determined solely by the static logic states applied to those pins, as defined in the device's truth table.

Does the 74AXP1T57 support true bidirectional level translation?

No - the 74AXP1T57 performs unidirectional level translation only: inputs are referenced to VCCI and the output is referenced to VCCO. Signal flow is strictly A/B/C → Y. For bidirectional translation (e.g., I²C), a dedicated bus switch or dual-channel solution is required.

How does the IOFF feature behave when only VCCI or only VCCO is powered?

When VCCI = 0 V (regardless of VCCO), all inputs are disabled and Y enters high-impedance. When VCCO = 0 V (regardless of VCCI), the output stage is disabled and Y is high-Z. In both cases, IOFF blocks current flow through the output, protecting downstream circuitry during asymmetric power sequencing.

Can the 74AXP1T57 operate with VCCI = 0.7 V and VCCO = 5.5 V simultaneously?

Yes - the device is fully specified for simultaneous operation across its full rated ranges: VCCI = 0.7–2.75 V and VCCO = 1.2–5.5 V. This combination is commonly used to interface advanced low-voltage processors with legacy 5 V peripherals while maintaining noise immunity and low power.
