Nexperia USA Inc. 74AUP1G57GXZ

Overview

74AUP1G57GXZ from Nexperia is a low-power configurable multiple-function logic gate with Schmitt-trigger inputs, supporting AND, OR, NAND, NOR, XNOR, inverter, and buffer configurations via its 3-bit input control (A/B/C). It operates across 0.8 V to 3.6 V supply, delivers ≤0.9 μA max ICC at 125 °C, and features IOFF partial power-down protection. It is used in battery-powered sensor interfaces and portable I/O expansion where voltage flexibility and ultra-low static power are critical.

For engineers reviewing the 74AUP1G57GXZ datasheet, 74AUP1G57GXZ pinout, 74AUP1G57GXZ application, or 74AUP1G57GXZ equivalent, this page provides verified functional configuration details, validated Schmitt-trigger hysteresis values (e.g., VH = 0.79–1.31 V at VCC = 3.0 V), IOFF leakage limits (±0.75 μA at −40 °C to +125 °C), and package-specific thermal derating for SOT1255-2 (X2SON6).

Technical Context

The device implements a single-output, three-input configurable logic cell using CMOS architecture with Schmitt-trigger inputs-enabling robust noise immunity (hysteresis up to 1.31 V) and reliable switching in noisy environments. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

All inputs (A, B, C) and output (Y) are overvoltage tolerant to 3.6 V independent of VCC, and the logic function is selected solely by hard-wiring A/B/C to VCC or GND-no clock, enable, or programming interface required. Propagation delay ranges from 1.5 ns (VCC = 3.0 V, CL = 5 pF) to 7.4 ns (VCC = 0.8 V, CL = 30 pF), with CPD = 4.3 pF at 3.6 V enabling precise dynamic power estimation.

FAQ

What logic functions can 74AUP1G57GXZ implement, and how is configuration performed?

It implements AND, OR, NAND, NOR, XNOR, inverter, and buffer functions. Configuration is achieved by hard-wiring the three inputs A, B, and C to either VCC or GND-no clock, serial interface, or programming is required. The function is determined solely by the static voltage levels applied, as defined in the datasheet's Function Selection Table (Table 5).

Does 74AUP1G57GXZ support partial power-down, and what is the IOFF leakage specification?

Yes-it features an integrated IOFF circuit that places the output in high-impedance state when VCC = 0 V, preventing back-current flow. At −40 °C to +125 °C and VCC = 0 V, IOFF leakage is specified at ±0.75 μA maximum, ensuring safe operation in multi-rail hot-swap scenarios.

What is the significance of the Schmitt-trigger input hysteresis, and how does it vary with supply voltage?

Schmitt hysteresis (VH = VT+ − VT−) rejects noise on slow or noisy inputs. At VCC = 3.0 V, VH ranges from 0.79 V (min) to 1.31 V (max); at VCC = 1.4 V, it is 0.18–0.56 V. This scalable hysteresis ensures consistent noise margin across the full 0.8–3.6 V operating range.

How does the X2SON6 (SOT1255-2) package impact thermal performance compared to other variants?

The X2SON6 package features enhanced thermal conductivity due to its 1.0 × 0.8 mm footprint and 0.32 mm height, with total power dissipation derating at 3.3 mW/K above +75 °C. Its smaller size and lower thermal resistance improve heat spreading in dense layouts versus TSSOP6 or larger XSON6 variants.
