Product details
Overview
74AHC1G07QSE-7 from Diodes Incorporated is an automotive-grade single non-inverting buffer with open-drain output, designed for level translation and wired-OR logic in 2.0V–5.5V systems. It delivers 8mA sink current at VCC = 4.5V, supports –40°C to +125°C operation, and features Schmitt-trigger inputs for noise immunity in noisy industrial or automotive signal conditioning paths.
For engineers reviewing the 74AHC1G07QSE-7 datasheet, 74AHC1G07QSE-7 pinout, 74AHC1G07QSE-7 application, or 74AHC1G07QSE-7 equivalent, key selection criteria include open-drain drive strength, AEC-Q100 Grade 1 qualification, input voltage tolerance beyond VCC, propagation delay (≤7.0 ns at 5V/50pF), and SOT353 package thermal resistance (θJA = 385°C/W).
Technical Context
This device implements a positive Boolean function (Y = A) with no internal inversion, requiring an external pull-up resistor to establish HIGH logic states. Its open-drain architecture enables bus sharing and active-low wired-OR configurations in I²C, SMBus, and interrupt-line aggregation circuits.
Schmitt-trigger inputs provide hysteresis (typ. 0.3V at VCC = 3.3V), enabling robust operation with slow-rising signals from sensors or mechanical switches. Input voltage range extends to –0.5V to 6.5V, independent of VCC, supporting mixed-voltage interfacing without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0V to 5.5V - Enables direct interface with 3.3V and 5V microcontrollers and legacy logic families. |
| Output Sink Current | 8mA at VCC = 4.5V - Drives standard LED indicators or pulls down 4.7kΩ pull-ups on 5V buses. |
| Propagation Delay | ≤7.0 ns (5V, CL = 50pF) - Supports >100 MHz toggle rates in timing-critical control signaling. |
| Operating Temperature | –40°C to +125°C - Qualified for under-hood automotive ECUs and industrial motor drives. |
| Input Hysteresis | Typ. 0.3V at VCC = 3.3V - Rejects up to 300mV of noise on switch debouncing or sensor inputs. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | CMOS-compatible input accepting voltages up to 6.5V; Schmitt-triggered for noise margin. |
| 2 (GND) | Ground Reference | Return path for output sink current and internal logic; must be low-impedance for stable switching. |
| 3 (NC) | No Connection | Internally unconnected pin; must remain floating or grounded per layout best practices. |
| 4 (Y) | Open-Drain Output | Active-low output capable of sinking 8mA; requires external pull-up to define HIGH state voltage. |
| 5 (VCC) | Power Supply | Supplies core logic and output driver; bypass capacitor (100nF) recommended within 5mm. |

Applications
| Automotive Body Control Module | Industrial Sensor Interface |
|---|---|

Use Scenario: Aggregating door-open, hood-open, and trunk-open switch signals onto a shared interrupt line to MCU. IC Role / Device Role / Timing Role: Open-drain buffer performing active-low wired-OR logic to combine multiple mechanical switch inputs. Use Value: Eliminates need for discrete diodes or additional logic gates; Schmitt inputs suppress contact bounce without external RC filtering. |
Use Scenario: Level-shifting analog sensor outputs (e.g., thermistor divider) to digital GPIOs on 3.3V microcontrollers. IC Role / Device Role / Timing Role: Non-inverting buffer isolating high-impedance sensor nodes while providing rail-tolerant input and 5V-compatible open-drain output. Use Value: Input accepts 0–5V sensor swing directly; output sinks MCU GPIO pull-down current without loading source. |
| I²C Bus Voltage Translation | LED Status Indicator Driver |
|
Use Scenario: Enabling bidirectional communication between 5V master and 3.3V slave devices on same I²C bus segment. IC Role / Device Role / Timing Role: Open-drain repeater buffering SDA/SCL lines with matched rise/fall characteristics. Use Value: Maintains I²C timing budgets (tBUF, tR) due to balanced drive capability and ≤7ns propagation delay. |
Use Scenario: Driving red/green dual-color LED indicators from microcontroller GPIO pins with current limiting. IC Role / Device Role / Timing Role: Output-stage buffer sinking up to 8mA per LED anode tied to VCC via resistor. Use Value: Reduces GPIO current burden; enables consistent brightness across 2.0–5.5V supply rails without recalculating Rlimit. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Wider VCC range (1.65–5.5V); lower max sink current (24mA @ 3.3V vs. 8mA @ 4.5V); no AEC-Q100 qualification. | Not suitable for automotive Grade 1 environments; preferred for cost-sensitive consumer electronics with 1.8V logic. | Select when operating below 2.0V or requiring higher sink current at 3.3V, but verify temperature and qualification requirements. |
| 74AUP1G07GW,125 | Lower static current (max 0.9µA); slower propagation (12.3ns @ 3.3V); operates down to 0.8V; AEC-Q100 Grade 2 only (–40°C to +105°C). | Limited to cabin electronics or infotainment subsystems; insufficient for engine bay or transmission control units. | Choose for ultra-low-power always-on monitoring circuits where speed is secondary and ambient temperature stays ≤105°C. |
Compared with SN74LVC1G07DBVR and 74AUP1G07GW,125, the 74AHC1G07QSE-7 uniquely combines AEC-Q100 Grade 1 qualification, 2.0–5.5V operation, and Schmitt-trigger inputs - making it the only option validated for under-hood signal conditioning with noise-prone sources.

FAQ
Can the 74AHC1G07QSE-7 operate with a 1.8V supply?
No. The absolute minimum recommended supply voltage is 2.0V per the datasheet's Recommended Operating Conditions table. At 1.8V, output drive strength drops below specification, propagation delay increases unpredictably, and AEC-Q100 qualification no longer applies. Use 74AUP1G07 for 1.8V operation.
Is an external pull-up resistor required for normal operation?
Yes. The open-drain output cannot source current; a pull-up resistor to VCC or another logic rail is mandatory to establish a valid HIGH logic level. Typical values range from 2.2kΩ (for speed) to 10kΩ (for low power), depending on bus capacitance and rise-time requirements.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies switching characteristics up to 50pF. Driving >50pF increases propagation delay nonlinearly and may cause ringing or false triggering. For loads >50pF, add a series resistor (22–100Ω) near the output pin to dampen reflections and maintain signal integrity.
Does the NC pin require any PCB layout treatment?
Yes. Pin 3 (NC) must not be soldered to ground or VCC. Leave it unconnected and avoid routing traces beneath it. In SOT353 layouts, ensure the NC pad is either omitted or isolated with solder mask to prevent accidental shorts during reflow or handling.
