Nexperia USA Inc. 74AXP1T57GTX

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 pins (VCCI: 0.7–2.75 V; VCCO: 1.2–5.5 V). It supports seven logic functions (AND, OR, NAND, NOR, XNOR, inverter, buffer) and enables voltage-level translation between disparate domains. Used in low-power I/O bridging for mixed-voltage microcontroller interfaces.

For engineers reviewing the 74AXP1T57 datasheet, 74AXP1T57 pinout, 74AXP1T57 application, or 74AXP1T57 equivalent, key selection criteria include dual-supply flexibility, sub-1 pF input capacitance, IOFF-enabled partial power-down, Schmitt-trigger noise immunity, and support for industrial temperature range (−40 °C to +125 °C).

Technical Context

The device implements a single configurable gate using pass-transistor logic controlled by input combinations, enabling reconfigurable Boolean functions without external wiring. Its Schmitt-trigger inputs provide hysteresis (0.2–1.0 V) for robust noise rejection on slow or noisy signals.

VCCI powers input circuitry and references all inputs; VCCO powers output drivers and defines output logic levels. The IOFF circuit disables output leakage when either supply is at 0 V, preventing backflow current during power sequencing - critical for hot-swap and partial-down systems.

FAQ

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

The 74AXP1T57 implements AND, OR, NAND, NOR, XNOR, inverter, and buffer functions. Configuration is achieved solely by hardwiring the A, B, and C inputs to VCCI or GND - no external programming or configuration pins are required. Each input combination maps deterministically to a specific logic function per Table 4 in the datasheet.

Can VCCI and VCCO be powered from the same supply rail?

Yes, VCCI and VCCO may share a common supply (e.g., both at 3.3 V), but they must be decoupled independently with local 100 nF ceramic capacitors. Sharing rails forfeits level translation capability but retains all other features including Schmitt-trigger inputs and IOFF protection.

How does the IOFF feature behave during power sequencing?

IOFF activates automatically when either VCCI or VCCO drops below ~0.1 V, forcing Y into high-impedance state with leakage <±2.0 μA (125 °C). This prevents back-current flow from a live VCCO domain into a powered-down VCCI domain - critical for safe hot-plug and staggered power-up sequences.

Is the 74AXP1T57 compatible with 1.8 V LVTTL or 2.5 V CMOS logic families?

Yes - when VCCI = 1.8 V, inputs meet LVTTL thresholds (VIH ≥ 1.17 V, VIL ≤ 0.63 V); when VCCI = 2.5 V, inputs satisfy CMOS thresholds (VIH ≥ 1.7 V, VIL ≤ 0.7 V). Output swing follows VCCO, so Y delivers full 1.8 V or 2.5 V logic levels when VCCO is set accordingly.
