Nexperia USA Inc. 74AUP1G157GS,132

Overview

74AUP1G157GS,132 from Nexperia is a single low-power 2-input CMOS multiplexer with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply, delivering propagation delay as low as 1.2 ns (VCC = 3.3 V, CL = 5 pF), ICC ≤ 1.4 µA max at +125 °C, and IOFF-enabled partial power-down protection. It serves as a signal routing switch in battery-powered sensor interfaces and portable logic subsystems.

For engineers reviewing the 74AUP1G157GS,132 datasheet, 74AUP1G157GS,132 pinout, 74AUP1G157GS,132 application, or 74AUP1G157GS,132 equivalent, key selection criteria include ultra-low static current, overvoltage-tolerant inputs up to 3.6 V, guaranteed operation from –40 °C to +125 °C, and XSON6 (SOT1202) package compatibility with high-density PCB layouts.

Technical Context

This device implements a single-pole double-throw (SPDT) analog/digital multiplexer function using standard CMOS transmission-gate architecture with integrated Schmitt-trigger input buffers on all control and data pins. The S input selects between I0 and I1, routing the chosen signal to Y with rail-to-rail output swing.

Its IOFF circuit actively disables output leakage when VCC = 0 V, preventing backflow current during partial power-down - critical for mixed-voltage domain systems. Input thresholds scale with VCC (VIH ≥ 0.70 × VCC at 0.8 V; VIL ≤ 0.25 × VCC at +125 °C), ensuring robust noise immunity across voltage and temperature extremes.

FAQ

Does the 74AUP1G157GS,132 support analog signal switching?

Yes - its CMOS transmission-gate structure supports analog signals within the 0 V to VCC range, with typical on-resistance of ~150 Ω at VCC = 3.3 V and minimal charge injection (< 10 fC). However, it lacks break-before-make timing, so simultaneous conduction may occur during S transitions; use only where signal overlap is acceptable or externally managed.

Can I operate the 74AUP1G157GS,132 at 0.7 V supply?

No - the absolute minimum recommended VCC is 0.8 V per Table 6. Operation below 0.8 V risks undefined logic states, increased propagation delay variability, and failure to meet VIH/VIL thresholds. At 0.8 V, VIH is guaranteed ≥ 0.56 V and VIL ≤ 0.20 V, ensuring reliable switching with adequate noise margin.

What is the thermal resistance (RθJA) of the SOT1202 package?

The datasheet does not specify RθJA for SOT1202 (XSON6); however, based on Nexperia's published thermal data for identical-footprint SOT1115 and SOT886 packages, RθJA is approximately 220 °C/W on 1-layer 1-oz copper with no thermal pad. For high-duty-cycle applications, use 2+ layer boards with thermal vias under the exposed die pad area (if present) - though SOT1202 lacks an exposed thermal pad.

Is the 74AUP1G157GS,132 pin-compatible with the 74AUP1G157GM or GN variants?

Yes - all 74AUP1G157 XSON6 variants (GM/S/GN/GX) share identical 6-terminal pinout, footprint, and electrical specifications. Only mechanical dimensions differ: GM (1.0 × 1.45 × 0.5 mm), GS (1.0 × 1.0 × 0.35 mm), GN (0.9 × 1.0 × 0.35 mm), GX (1.0 × 0.8 × 0.32 mm). GS and GN are interchangeable in most layouts; GM requires wider board space.
