Nexperia USA Inc. 74AUP1G16GWH

Overview

74AUP1G16GWH from Nexperia is a single-channel low-power Schmitt-trigger buffer IC operating from 0.8 V to 3.6 V supply, delivering 0.9 μA max ICC static current, 1.4 ns min propagation delay at 3.0 V/CL=5 pF, and IOFF-enabled partial power-down protection. It serves as a level-shifting signal conditioner in ultra-low-power sensor interfaces and battery-powered microcontroller I/O expansion.

For engineers reviewing the 74AUP1G16GWH datasheet, 74AUP1G16GWH pinout, 74AUP1G16GWH application, or 74AUP1G16GWH equivalent, key selection criteria include its guaranteed operation down to 0.8 V, ±0.75 μA max input leakage over –40 °C to +125 °C, Schmitt-trigger hysteresis for noisy rail-to-rail inputs, and TSSOP5 (SOT353-1) package compatibility with high-density PCB layouts.

Technical Context

This device implements a non-inverting buffer with integrated Schmitt-trigger inputs, enabling robust signal conditioning of slow-rising or noisy digital signals across its full 0.8 V–3.6 V VCC range. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

Static performance is specified across three temperature grades: –40 °C to +125 °C (max ICC = 1.4 μA), –40 °C to +85 °C (max ICC = 0.9 μA), and 25 °C (typical ICC = 0.5 μA). Dynamic behavior includes CL-dependent propagation delays (e.g., 1.4–4.2 ns at VCC = 3.0–3.6 V, CL = 5–30 pF) and CPD = 4.0 pF at 3.0–3.6 V for dynamic power estimation.

FAQ

What is the maximum allowable input voltage when VCC = 0 V?

The absolute maximum input voltage is +4.6 V per Table 5, and the device tolerates inputs up to 3.6 V regardless of VCC state. With VCC = 0 V, the IOFF circuit blocks current flow, allowing safe application of 3.3 V or 2.5 V signals from powered subsystems without damage or backfeed.

Does the 74AUP1G16GWH support true bidirectional operation?

No - it is a unidirectional non-inverting buffer with dedicated input (A) and output (Y) pins. There is no internal direction control or bus-hold functionality. For bidirectional data transfer, discrete dual-Schmitt buffers or dedicated transceivers like 74AUP2G240 must be used.

How does the Schmitt-trigger input affect timing parameters?

The Schmitt-trigger adds hysteresis (typically 100 mV at 1.2 V), which eliminates multiple transitions on slow edges but does not alter propagation delay specifications. All tPD values in Table 8 are measured using standard 50% VCC switching thresholds at VM = 0.5 × VCC, independent of hysteresis.

Can the n.c. pin (Pin 1) be used as a thermal pad or ground tie?

No - Pin 1 is internally not connected. The datasheet explicitly states "not connected" in Table 3 and shows no bond wire in Fig. 6. Using it as a thermal pad or ground tie violates the SOT353-1 mechanical specification and may compromise solder joint reliability or cause misalignment during reflow.
