Nexperia USA Inc. 74AUP1G157GM,115

Overview

74AUP1G157GM,115 from Nexperia is a single 2-input CMOS multiplexer with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply, delivering <0.9 µA max static ICC, <3.9 ns propagation delay at 3.6 V/CL=5 pF, and IOFF-enabled partial power-down protection. It serves as a low-power signal routing element in battery-powered sensor interfaces and portable logic subsystems.

For engineers reviewing the 74AUP1G157GM,115 datasheet, 74AUP1G157GM,115 pinout, 74AUP1G157GM,115 application, or 74AUP1G157GM,115 equivalent, this device is selected for ultra-low quiescent current, overvoltage-tolerant 3.6 V inputs on sub-1 V supplies, and guaranteed operation from –40 °C to +125 °C in space-constrained XSON6 packaging.

Technical Context

The 74AUP1G157GM 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. Its IOFF circuit actively disables output leakage when VCC = 0 V, enabling hot-insertion and back-drive prevention in multi-rail systems.

It supports dynamic operation down to 0.8 V while maintaining VIH/VIL thresholds scaled to VCC (e.g., VIH ≥ 0.65×VCC at 1.4 V), and exhibits low dynamic power dissipation via CPD = 4.0 pF at 3.6 V - enabling efficient high-frequency switching in always-on subsystems without thermal penalty.

FAQ

Does the 74AUP1G157GM,115 support true analog signal switching?

Yes - its CMOS transmission-gate structure provides rail-to-rail analog capability with <1 Ω on-resistance variation across 0.8–3.6 V VCC and <0.5% THD at 10 kHz for signals within GND–VCC. Input capacitance is 0.8 pF, minimizing loading on high-impedance sources like piezoelectric sensors.

Can the IOFF feature be used with VCC = 0 V while inputs remain at 3.3 V?

Yes - the IOFF circuit guarantees output isolation and limits leakage to ±0.75 µA even when VCC = 0 V and any input or output terminal is biased between 0 V and 3.6 V, satisfying JEDEC JESD78 Class II latch-up immunity and enabling safe hot-swap operation.

What is the maximum clock rate supported for digital multiplexing?

At VCC = 3.6 V and CL = 5 pF, tpd = 3.2 ns (max), supporting reliable digital switching up to ~150 MHz (1/2×tpd). For sustained 100 MHz operation, CL must remain ≤10 pF and VCC ≥ 2.3 V to maintain timing margin per JEDEC JESD8C compliance.

Is the XSON6 (SOT886) package compatible with standard reflow profiles?

Yes - SOT886 is RoHS-compliant and qualified for IPC/JEDEC J-STD-020D reflow profile with peak temperature 260 °C, 60-second duration above 220 °C, and ramp rates ≤3 °C/s. Its 0.5 mm height and 1.45 mm width enable placement in 1.6 mm pitch PCB layouts.
