Nexperia USA Inc. 74AXP1G157GMH

Overview

74AXP1G157GMH from Nexperia is a single 2-input Schmitt-trigger multiplexer operating from 0.7 V to 2.75 V supply, selecting between I0 and I1 based on S input and delivering true (non-inverted) output Y. It features IOFF partial power-down protection, 0.5 pF typical input capacitance, and −40 °C to +85 °C operation in XSON6 (SOT886) package. Used in low-voltage signal routing for portable sensor interfaces and battery-powered logic consolidation.

For engineers reviewing the 74AXP1G157GMH datasheet, 74AXP1G157GMH pinout, 74AXP1G157GMH application, or 74AXP1G157GMH equivalent, key selection criteria include ultra-low static current (0.6 µA max at 85 °C), sub-1 ns propagation delay at 2.3–2.7 V, IOFF-enabled system-level power gating, and JEDEC-compliant voltage thresholds across 1.1–2.7 V ranges.

Technical Context

This device implements a single-pole double-throw (SPDT) analog/digital signal selector with Schmitt-trigger inputs enabling robust noise immunity on slow-rising control and data lines. Its IOFF circuit actively disables output leakage when VCC = 0 V, preventing backflow current during partial power-down sequences in multi-rail systems.

It supports dynamic operation across five JEDEC voltage bands (1.1–1.3 V, 1.4–1.6 V, etc.), with propagation delays tightly specified from 0.9 ns (min, 2.3–2.7 V) to 138 ns (max, 0.75–0.85 V). Input and output voltage tolerances extend to 2.75 V independent of VCC, enabling level-shifting flexibility.

FAQ

Does 74AXP1G157GMH support level shifting between different VCC domains?

Yes - its inputs tolerate up to 2.75 V regardless of VCC, and output swing tracks VCC. When VCC = 1.2 V and I0 = 1.8 V, the device passes the signal but clamps output to 1.2 V logic levels, enabling controlled unidirectional level translation without external components.

What is the minimum VCC required for guaranteed functionality at 85 °C?

The datasheet specifies 0.7 V minimum VCC across −40 °C to +85 °C. At 85 °C, static current remains ≤0.6 µA and propagation delay stays within 138 ns (0.75–0.85 V band), confirming full functionality down to 0.7 V under worst-case thermal conditions.

Can the 74AXP1G157GMH be used with AC-coupled inputs?

No - Schmitt-trigger inputs require DC bias within the valid VIH/VIL windows defined per VCC band. AC coupling removes DC reference, causing undefined switching behavior; a pull-up/pull-down network must establish proper DC operating point.

How does IOFF behave when VCC is ramping from 0 V to nominal?

IOFF activates when VCC falls below ~0.2 V and remains active until VCC exceeds ~0.4 V. During this transition, output is actively held high-impedance with leakage <±0.1 µA, preventing contention or backfeed during power-up/power-down sequencing in multi-rail systems.
