Product details

Overview

74AUP3G07DCH from Nexperia is a triple non-inverting buffer IC with open-drain outputs, designed for level-shifting and wired-OR/AND bus interfacing in ultra-low-power systems. It operates across 0.8 V to 3.6 V supply, features Schmitt-trigger inputs for noise immunity, delivers ICC ≤ 1.4 μA max at −40 °C to +125 °C, and supports partial power-down via IOFF circuitry. It is used in I²C bus extension, voltage-level translation between mixed-supply domains, and low-noise sensor interface logic.

For engineers reviewing the 74AUP3G07DCH datasheet, 74AUP3G07DCH pinout, 74AUP3G07DCH application, or 74AUP3G07DCH equivalent, key selection criteria include its guaranteed open-drain drive capability (IO = 4 mA at VCC = 3.0 V), sub-1 ns propagation delay at 3.3 V with 5 pF load, −40 °C to +125 °C temperature rating, and compatibility with JEDEC standards JESD8-12 through JESD8-B.

Technical Context

This device integrates three independent non-inverting buffers, each with an open-drain output stage enabling wired-logic configurations. All inputs incorporate Schmitt-trigger action, ensuring clean signal regeneration even with slow-rising/falling edges across the full 0.8 V–3.6 V VCC range.

The IOFF circuit actively disables outputs during partial power-down, blocking backflow current when VCC = 0 V. Input tolerance up to 3.6 V allows interfacing with higher-voltage logic without external level shifters, while dynamic power dissipation is governed by CPD = 1.2 pF (at VCC = 3.6 V) and scales quadratically with supply voltage and switching frequency.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.8 V to 3.6 V - enables operation across battery-powered, IoT, and multi-rail embedded systems without level-shifting circuitry.
Max ICC (Static)	1.4 μA at −40 °C to +125 °C - ensures negligible quiescent current in always-on monitoring nodes.
tpd (VCC = 3.3 V, CL = 5 pF)	1.1 ns to 3.6 ns - supports high-speed digital control signaling in compact timing-critical paths.
IO (Low-Level Output)	4.0 mA at VCC = 3.0 V - sufficient to drive standard I²C bus capacitance (≤ 400 pF) with defined VOL ≤ 0.50 V.
Input Voltage Tolerance	Up to 3.6 V - permits direct connection to 3.3 V or 5 V logic outputs without clamping diodes or resistors.
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-range edge sensors.
ESD Protection	HBM > 5000 V, CDM > 1000 V - reduces field failure risk in manual handling and unshielded PCB assembly environments.

Pinout & Package

VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; lead pitch 0.5 mm; exposed pad not present.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 6	1A, 2A, 3A	Independent logic inputs - accept 0.8–3.6 V signals; Schmitt-triggered for noise rejection on noisy PCB traces.
2, 5, 7	3Y, 2Y, 1Y	Open-drain outputs - require external pull-up for active-HIGH operation; enable wired-AND/OR bus topologies.
4	GND	Reference ground - must be low-impedance connection to minimize ground bounce in multi-buffer layouts.
8	VCC	Power supply - decoupling capacitor (100 nF ceramic) required within 3 mm of pin for stable high-speed switching.

Key Features

Feature	Design Value
Wide VCC range	0.8 V to 3.6 V - eliminates need for separate voltage regulators in mixed-supply SoC interfaces.
IOFF partial power-down	Blocks backflow current when VCC = 0 V - prevents unintended power injection into powered-down subsystems.
Schmitt-trigger inputs	Hysteresis ≥ 0.1 × VCC - rejects EMI-induced glitches on long traces or unshielded cables in industrial settings.
Low dynamic noise	Overshoot/undershoot < 10 % of VCC - minimizes crosstalk in dense routing on 4-layer PCBs.
JEDEC compliance	JESD8-12 through JESD8-B - guarantees interoperability with legacy and next-gen logic families across voltage bands.

Applications

Industrial Sensor Hub

I²C Bus Extender

Use Scenario: Aggregating analog sensor outputs (temperature, humidity, pressure) into a microcontroller via shared I²C bus with long trace lengths (>15 cm).

IC Role / Device Role / Timing Role: Open-drain buffer isolates MCU I²C pins from bus capacitance and noise; enables bidirectional signal conditioning without direction control lines.

Use Value: Maintains I²C timing integrity (tBUF, tHD:STA) across 400 pF total bus load while reducing MCU GPIO stress and ESD susceptibility.

Use Scenario: Connecting multiple I²C slave devices across two PCBs with different ground potentials and supply voltages (e.g., 1.8 V sensor board ↔ 3.3 V host MCU).

IC Role / Device Role / Timing Role: Level-translating buffer provides galvanic isolation at signal layer; Schmitt inputs reject ground-shift-induced noise on interconnect cables.

Use Value: Eliminates need for dedicated level translators or optocouplers; preserves I²C clock stretching behavior and ACK/NACK timing margins.

Low-Power Wearable Controller

Automotive Body Control Module

Use Scenario: Driving LED indicators and status flags from a 0.9 V ultra-low-power MCU core in a hearable device with strict 2 μA sleep budget.

IC Role / Device Role / Timing Role: Power-gated buffer stage - IOFF disables outputs during MCU deep-sleep, preventing leakage through pull-ups.

Use Value: Reduces system standby current by >95 % compared to direct GPIO driving with external pull-ups, extending battery life by months.

Use Scenario: Interfacing LIN transceiver status signals and door-lock actuator feedback to a 3.3 V microcontroller in a body control unit operating at 125 °C ambient.

IC Role / Device Role / Timing Role: Robust input buffer - tolerates 3.6 V tolerant inputs from 5 V LIN PHY, withstands thermal cycling, and suppresses ignition noise.

Use Value: Replaces discrete resistor-diode networks; achieves AEC-Q100 Grade 1 reliability without derating at junction temperatures up to 150 °C.

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple open-drain buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP 74LVC3G07DP	Wider VCC range (1.65 V–5.5 V); higher ICC (max 10 μA); no IOFF; no Schmitt inputs.	Requires external level shifting below 1.65 V; unsuitable for partial power-down systems.	Select only if interfacing with 5 V logic and thermal constraints allow higher static current.
Texas Instruments SN74LVC3G07DCU	Same VCC range (1.65 V–5.5 V); no Schmitt inputs; IOFF not implemented; higher tpd (min 3.5 ns @ 3.3 V).	Lacks noise immunity on slow edges; cannot safely isolate powered-down sections.	Prefer only for cost-sensitive consumer designs where EMI environment is controlled and power sequencing is simple.

Compared with NXP 74LVC3G07DP and TI SN74LVC3G07DCU, the 74AUP3G07DCH uniquely combines sub-μA static current, Schmitt-trigger noise rejection, and IOFF-enabled safe power sequencing - making it the sole choice for battery-constrained, thermally aggressive, or electrically noisy applications requiring reliable open-drain logic.

FAQ

What is the maximum capacitive load the 74AUP3G07DCH can drive while maintaining specified tpd?

The datasheet specifies propagation delay (tpd) performance up to 30 pF load capacitance across all VCC conditions. At VCC = 3.3 V and CL = 30 pF, tpd remains ≤ 11.4 ns (−40 °C to +125 °C). Driving loads beyond 30 pF increases delay nonlinearly and may violate setup/hold timing in synchronous interfaces; external buffering is recommended above this limit.

Can the 74AUP3G07DCH be used to translate between 1.8 V and 3.3 V logic without external components?

Yes - its 3.6 V-tolerant inputs accept 1.8 V or 3.3 V signals directly, and its open-drain outputs can be pulled up to either voltage rail. For 1.8 V → 3.3 V translation, connect the pull-up to 3.3 V; for 3.3 V → 1.8 V, pull up to 1.8 V and ensure the driven device accepts 1.8 V logic-high thresholds. No series resistors or level shifters are needed.

Does the IOFF feature activate automatically when VCC drops below a threshold?

Yes - the IOFF circuit engages when VCC falls below approximately 0.2 V, disabling all outputs and limiting power-off leakage current to ±0.75 μA (max) regardless of input/output voltage states. This occurs without external control signals and protects downstream circuitry from backfeeding during brown-out or hot-swap events.

Is the 74AUP3G07DCH pin-compatible with other 74AUP3Gxx variants in VSSOP8 package?

No - pinouts differ across the 74AUP3Gxx family. The 74AUP3G07DCH (buffer) uses pins 1/3/6 for inputs and 2/5/7 for outputs in SOT765-1. In contrast, 74AUP3G14 (inverter) swaps input/output assignments, and 74AUP3G17 (Schmitt buffer) shares the same pinout but lacks open-drain outputs. Always verify pin configuration per device datasheet.
