Product details
Overview
74AHCT1G04QSE-7 from Diodes Incorporated is an AEC-Q100 Grade 1 qualified single inverter gate IC with push-pull output, operating from 4.5V to 5.5V supply, delivering ±8mA drive at 5V, featuring Schmitt-trigger inputs for noise immunity, and rated for -40°C to +125°C ambient temperature - used in automotive body control modules for signal conditioning of switch inputs.
For engineers reviewing the 74AHCT1G04QSE-7 datasheet, 74AHCT1G04QSE-7 pinout, 74AHCT1G04QSE-7 application, or 74AHCT1G04QSE-7 equivalent, this page provides verified package mapping (SOT353), propagation delay (≤8.5ns @ -40°C to +125°C), input voltage tolerance beyond VCC, latch-up immunity (>100mA), and ESD robustness (2kV HBM).
Technical Context
The 74AHCT1G04QSE-7 implements a single inverting logic function (Y = A̅) using CMOS technology with Schmitt-trigger inputs, enabling reliable operation with slow-rising or noisy digital signals. Its input voltage range extends to -0.5V–6.5V, independent of VCC, and it maintains balanced high/low drive strength (±8mA at 5V).
Designed for automotive Grade 1 environments, it meets AEC-Q100 stress tests including 2kV HBM ESD, 1kV CDM, and >100mA latch-up immunity. Propagation delay is specified up to 8.5ns under worst-case conditions (-40°C to +125°C, CL = 15pF), with thermal resistance θJA = 385°C/W in SOT353.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Inverter (Y = A̅); single-channel, non-inverting input polarity not supported. |
| Supply Voltage Range | 4.5V–5.5V; ensures compatibility with 5V automotive microcontroller I/O domains. |
| Output Drive | ±8mA at VCC = 5V; sufficient to directly drive LED indicators or interface with TTL/CMOS loads. |
| Propagation Delay | ≤8.5ns max (CL = 15pF, -40°C to +125°C); supports timing-critical signal inversion in real-time control loops. |
| Input Threshold | Schmitt-trigger hysteresis (typ. 0.4V); rejects noise on low-slew-rate inputs like mechanical switches or sensors. |
| ESD Rating | 2000V HBM per AEC-Q100-002; eliminates need for external TVS protection in most board-level designs. |
| Operating Temp | -40°C to +125°C ambient (Grade 1); validated for engine bay, transmission control, and ADAS sensor interfaces. |
Pinout & Package
74AHCT1G04QSE-7 is housed in a 5-pin SOT353 (SC-70-5) package measuring 2.15mm × 2.1mm × 1.1mm with 0.65mm lead pitch and matte tin-plated leads compliant with MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | Active-low Schmitt-trigger input; accepts voltages up to 6.5V regardless of VCC. |
| 2 (GND) | Ground Reference | Return path for all internal logic and output current; must be low-impedance for stable noise margin. |
| 3 (Y) | Data Output | Inverted push-pull output; sinks or sources up to 8mA while maintaining VOH ≥3.7V / VOL ≤0.55V. |
| 4 (VCC) | Power Supply | Primary 4.5–5.5V supply rail; decoupling capacitor (≥100nF) required within 5mm of this pin. |
| 5 (NC) | No Connection | Internally unconnected; must remain floating - no PCB trace or solder mask opening required. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables clean switching on slow or noisy signals (e.g., door switch bounce, potentiometer wiper noise). |
| Input voltage beyond VCC | Supports mixed-voltage interfacing - e.g., 3.3V FPGA driving 5V logic without level shifters. |
| AEC-Q100 Grade 1 qualification | Validated for automotive under-hood use with full PPAP documentation and IATF 16949 manufacturing. |
| Low power consumption | ICC ≤40μA max at 5.5V and +125°C - reduces thermal load in sealed ECUs. |
| High ESD/latch-up immunity | 2kV HBM and >100mA latch-up rating eliminate field failures due to handling or system transients. |
Applications
| Automotive Body Control | Industrial Sensor Interface |
|---|---|
|
Use Scenario: Signal conditioning of mechanical door latch switches in vehicle body control units. IC Role / Device Role / Timing Role: Inverts open/closed switch state and cleans contact bounce via Schmitt-trigger action. Use Value: Eliminates need for RC filtering or firmware debouncing, reducing BOM cost and MCU interrupt load. |

IC Role / Device Role / Timing Role: Converts slow-rising thermistor or pressure sensor signals into clean 5V logic levels. Use Value: Maintains signal integrity across long cable runs where EMI induces edge jitter. |
| ADAS Camera Power Sequencing | Automotive Lighting Control |
|
Use Scenario: Enabling camera module power rails only after host processor asserts valid enable signal. IC Role / Device Role / Timing Role: Inverts processor GPIO to activate high-side load switch with precise timing control. Use Value: Ensures strict power-up sequencing compliance per ISO 26262 ASIL-B subsystem requirements. |
Use Scenario: Driving LED driver enable pins in adaptive front lighting systems (AFS). IC Role / Device Role / Timing Role: Inverts PWM dimming signals to match active-low enable logic of LED drivers. Use Value: Provides deterministic signal polarity conversion without adding propagation delay skew. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Wider VCC range (1.65–5.5V); lower drive (±24mA @ 3.3V, but only ±4mA @ 5V); no AEC-Q100 qualification. | Targeted at consumer/industrial portable devices; lacks automotive reliability validation and extended temp support. | Select when dual-supply flexibility is needed and Grade 1 qualification is unnecessary. |
| MC74VHC1G04DTT1G | Same 4.5–5.5V range and AEC-Q100 Grade 1 rating; slightly higher tPD (max 10.5ns vs. 8.5ns); identical SOT353 footprint. | Validated for same automotive roles but with looser timing margin; RoHS-compliant but not halogen-free. | Use when exact pinout compatibility is required and marginal propagation delay increase is acceptable. |
Compared with SN74LVC1G04DBVR and MC74VHC1G04DTT1G, the 74AHCT1G04QSE-7 delivers tighter propagation delay control over full Grade 1 temperature range and includes halogen-free "Green" compliance - critical for OEM Tier 1 supply chain requirements.

FAQ
Is the 74AHCT1G04QSE-7 pin-compatible with other SOT353 inverters?
Yes - it uses standard SOT353 pinout (A-GND-Y-VCC-NC), matching industry-standard 5-pin SC-70 layouts. Pin 1 is input (A), pin 2 is GND, pin 3 is output (Y), pin 4 is VCC, and pin 5 is NC. No PCB redesign is needed when substituting functionally equivalent AEC-Q100 inverters in the same package.
Can the 74AHCT1G04QSE-7 operate with a 3.3V supply?
No - its absolute minimum VCC is 4.5V per the Recommended Operating Conditions table. At 3.3V, the device will not meet logic threshold specifications or output drive requirements; use SN74LVC1G04 instead for 3.3V operation.
What is the significance of the "Q" suffix in 74AHCT1G04QSE-7?
The "Q" denotes AEC-Q100 qualification per Diodes Incorporated's product definition - confirming full stress testing (ESD, latch-up, temperature cycling) and production in IATF 16949-certified facilities, with PPAP documentation available upon request.
Does the NC pin require any PCB layout treatment?
No - pin 5 is internally unconnected and must remain electrically floating. Do not tie it to GND, VCC, or any trace; avoid solder mask openings or copper features beneath it to prevent unintended coupling or contamination-related leakage paths.
