Product details
Overview
74AUP3G16GFX from Nexperia is a low-power triple buffer IC with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply range, delivering ICC ≤ 0.9 μA max static current, tPD ≤ 4.2 ns (VCC = 3.0–3.6 V, CL = 15 pF), and IOFF-enabled partial power-down protection. It is used in battery-powered sensor interfaces and level-shifting I/O expansion in portable industrial controllers.
For engineers reviewing the 74AUP3G16GFX datasheet, 74AUP3G16GFX pinout, 74AUP3G16GFX application, or 74AUP3G16GFX equivalent, key selection criteria include ultra-low ICC at sub-1-V operation, guaranteed IOFF behavior during VCC ramp-down, Schmitt-trigger noise immunity on all three inputs, and VSSOP8 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements three independent non-inverting buffers, each with Schmitt-trigger input thresholds that scale with VCC (e.g., VIH = 0.65×VCC min at 1.4 V) and hysteresis ≥ 0.1×VCC, enabling robust signal conditioning of slow-rising or noisy digital signals. All inputs tolerate up to 3.6 V regardless of VCC level.
The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA max over –40 °C to +125 °C, satisfying JEDEC JESD78B Class II latch-up immunity (>100 mA). Dynamic performance is characterized with CL = 5–30 pF loads and supports 1 MHz switching with CPD = 4.0 pF at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage (VCC) | 0.8 V to 3.6 V - enables direct interfacing with 0.9 V logic, 1.2 V cores, and 3.3 V peripherals without level shifters. |
| Max static supply current (ICC) | 0.9 μA at –40 °C to +125 °C - ensures <1 μW quiescent power at 1.8 V, critical for always-on sensor nodes. |
| Propagation delay (tPD) | 4.2 ns max at VCC = 3.0–3.6 V, CL = 15 pF - supports >100 MHz data throughput in buffered clock/data paths. |
| IOFF leakage (VI/VO = 0–3.6 V, VCC = 0 V) | ±0.75 μA max - prevents backfeed into powered-down subsystems, protecting downstream ICs during partial shutdown. |
| Input hysteresis | ≥0.1×VCC - rejects noise spikes up to 360 mV at 3.6 V, eliminating need for external RC filtering on slow GPIO lines. |
| ESD rating (HBM) | 5000 V - exceeds IEC 61000-4-2 Level 4, allowing direct handling in unshielded assembly environments. |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives without derating. |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8-pin, 2.3 mm body width, 0.5 mm lead pitch, 0.6 mm max height - optimized for high-density routing and thermal relief in compact PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | 1A / 2A / 3A | Independent Schmitt-trigger input pins - accept 0–3.6 V signals regardless of VCC; enable mixed-voltage domain interfacing. |
| 2, 5, 7 | 3Y / 2Y / 1Y | Non-inverting buffered outputs - drive capacitive loads up to 30 pF with controlled edge rates (200 ns/V min dV/dt). |
| 4 | GND | Dedicated ground reference - must be connected directly to low-impedance system ground plane to maintain noise immunity. |
| 8 | VCC | Single supply rail - powers all three buffers and IOFF circuitry; decoupling capacitor (100 nF) required within 2 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (0.8–3.6 V) | Eliminates need for separate voltage translators when connecting 0.9 V FPGA I/O banks to 3.3 V legacy peripherals. |
| Schmitt-trigger inputs | Provides ≥100 mV hysteresis at 1.2 V, rejecting EMI-induced glitches on long traces in motor control feedback loops. |
| IOFF partial power-down | Guarantees output high-impedance state with <1 μA leakage when VCC = 0 V, preventing bus contention in hot-swap applications. |
| Low dynamic power (CPD = 4.0 pF) | Enables 1 MHz toggling of all three outputs with <50 μW dynamic dissipation at 3.3 V, extending battery life in IoT endpoints. |
| JESD8-compliant voltage classes | Validated across five JEDEC standards (JESD8-12 through JESD8-B), ensuring interoperability with JEDEC-defined memory and interface ICs. |
Applications
| Industrial Sensor Interface | Portable Medical Device I/O |

Use Value: 0.9 μA ICC at 1.8 V extends 2-year battery life; IOFF blocks leakage when hub enters deep sleep (VCC = 0 V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G16DCUR | Higher ICC (10 μA typ), no Schmitt inputs, 1.65–5.5 V VCC range | Lacks noise immunity on slow edges; requires external filtering for noisy sensor lines | Select only if 5 V tolerance is required and input rise time >10 ns is guaranteed |
| 74LVC1G16GW | Single-channel, same VCC range and IOFF, but no Schmitt inputs | Requires three separate packages for triple buffering, increasing board area by 2.4× | Choose only when design allows discrete placement and layout space permits |
Compared with SN74LVC3G16DCUR and 74LVC1G16GW, the 74AUP3G16GFX uniquely combines ultra-low ICC (<1 μA), inherent Schmitt noise rejection, and triple-channel integration in VSSOP8 - making it the sole option for space- and power-constrained systems requiring robust signal conditioning without external components.

FAQ
Does 74AUP3G16GFX support true bidirectional operation?
No. The 74AUP3G16GFX is a unidirectional non-inverting buffer with fixed input (pins 1/3/6) and output (pins 2/5/7) assignments. It lacks direction-control pins or bus-switch functionality. For bidirectional data flow, consider dedicated bus transceivers like the 74LVC4245A.
Can 74AUP3G16GFX be used with VCC = 0.7 V?
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 - violating JEDEC JESD8-12 compliance and invalidating parametric guarantees.
What is the maximum capacitive load this device can drive reliably?
The datasheet characterizes performance up to 30 pF (Table 8), with tPD = 7.2 ns max at VCC = 3.0–3.6 V. Driving >30 pF increases delay nonlinearly and may cause overshoot/undershoot exceeding 10 % of VCC. For >30 pF loads, add series termination or use a higher-drive buffer.
Is pin 1 marking visible on the 74AUP3G16GFX VSSOP8 package?
Yes. Per Table 2 and Figure 6, the marking code "5A" appears adjacent to pin 1, which is located at the lower-left corner of the package body (below the marking), identified by a molded dot or beveled edge per JEDEC MO-187 standards for SOT765-1.
