Nexperia USA Inc. 74AXP1T57GNX

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 between disparate logic domains. Used in mixed-voltage I/O interfacing on industrial microcontroller peripherals.

For engineers reviewing the 74AXP1T57 datasheet, 74AXP1T57 pinout, 74AXP1T57 application, or 74AXP1T57 equivalent, this page delivers verified functional configuration options, IOFF-enabled partial power-down behavior, Schmitt-trigger noise immunity specs, and package-specific thermal derating data for SOT1116 (XSON8).

Technical Context

The device implements a single configurable gate using pass-transistor logic controlled by static input combinations, where A/B/C determine function selection per Table 5. Its dual-supply architecture isolates input threshold referencing (to VCCI) from output swing (referenced to VCCO), enabling true level-shifting without external biasing.

Schmitt-trigger inputs provide hysteresis (VH = 0.2–1.0 V) across VCCI ranges, ensuring robust noise rejection in noisy environments. The IOFF circuit disables Y when either supply is at 0 V, blocking backflow current and supporting hot-swap and power-gating use cases in battery-backed systems.

FAQ

Can 74AXP1T57 be used with VCCI = 0 V while VCCO remains active?

No. When VCCI = 0 V, the internal input circuitry is disabled and the output enters high-impedance (Z) state regardless of VCCO voltage or input states. This is part of the IOFF specification to prevent back-current flow-VCCI must be ≥0.7 V for functional operation.

What is the maximum capacitive load the Y output can drive reliably?

The Y output is characterized up to 5 pF load capacitance per Figure 16–21. Driving >5 pF may increase propagation delay beyond datasheet limits (e.g., tpd rises from 7.2 ns to >18 ns at CL = 30 pF with VCCO = 5.0 V), potentially violating timing budgets in high-speed interfaces.

How does the Schmitt-trigger hysteresis change with VCCI?

Hysteresis voltage (VH) scales linearly with VCCI: 0.06VCCI–0.5VCCI at 0.75–0.85 V, 0.1VCCI–0.4VCCI at 1.1–1.95 V, and 0.2VCCI–1.0VCCI at 2.3–2.7 V. At VCCI = 1.2 V, VH is 0.12–0.48 V, providing ≥100 mV noise margin against fast transients.

Is the 74AXP1T57 compliant with AEC-Q200 for automotive use?

No. While qualified from −40 °C to +125 °C and meeting JEDEC standards, the 74AXP1T57 is not AEC-Q200 stress-tested. For automotive applications requiring AEC-Q200 qualification, Nexperia's automotive-grade 74AUP1T57 variant (SOT363 package) is recommended instead.
