Product details
Overview
74AHCT1G04QW5-7 from Diodes Incorporated is an AEC-Q100 Grade 1 qualified single inverter gate (positive logic NOT function) with push-pull output, operating from 4.5V to 5.5V supply, delivering ±8mA drive at 5V, and rated for -40°C to +125°C ambient - used in automotive body control modules for signal inversion in sensor interface and LED driver enable paths.
For engineers reviewing the 74AHCT1G04QW5-7 datasheet, 74AHCT1G04QW5-7 pinout, 74AHCT1G04QW5-7 application, or 74AHCT1G04QW5-7 equivalent, key selection criteria include automotive temperature compliance, 5V CMOS logic compatibility, Schmitt-trigger input tolerance, propagation delay under 8.5ns at 125°C, and SOT25 package thermal resistance (θJA = 184°C/W).
Technical Context
This device implements a single inverting logic gate using advanced CMOS technology optimized for automotive-grade reliability. It features Schmitt-trigger inputs enabling robust operation with slow-rising/falling signals, and operates exclusively within the 4.5V–5.5V VCC range with rail-to-rail output swing.
All inputs tolerate voltages up to 6.5V independent of VCC, and the output stage provides symmetrical sourcing/sinking capability (±8mA at 5V). Propagation delays are balanced across rising/falling edges (tPLH ≈ tPHL), and latch-up immunity exceeds 100mA per AEC-Q100-004.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5V to 5.5V - ensures stable operation across automotive battery variations including cold-crank transients. |
| Output Drive | ±8mA at 5V - sufficient to directly drive multiple 74-series inputs or small LEDs without external buffering. |
| Propagation Delay | ≤8.5ns at VCC = 5V, CL = 15pF, TA = +125°C - supports >100MHz toggle rates in timing-critical control paths. |
| Input Threshold | VIL ≤ 0.8V, VIH ≥ 2.0V at 5V - compatible with TTL and 5V CMOS logic families without level shifting. |
| ESD Protection | 2kV HBM, 1kV CDM - meets AEC-Q100-002/-011 for assembly-line robustness and field reliability. |
| Operating Temp | -40°C to +125°C ambient - certified for engine bay, transmission control, and ADAS ECU placement. |
Pinout & Package
SOT25 (3.0mm × 2.8mm × 1.2mm, 0.95mm lead pitch) surface-mount package with moisture sensitivity level 1 (J-STD-020) and matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Logic Input | Inverting gate input; Schmitt-triggered for noise immunity on slow edges; voltage-tolerant up to 6.5V. |
| 2 (GND) | Ground Reference | Primary return path for all internal logic and output current; must be low-impedance for stable switching. |
| 3 (Y) | Logic Output | Inverted output with push-pull structure; drives high/low actively; supports 15pF load with <8.5ns delay at 125°C. |
| 4 (VCC) | Supply Voltage | 5V nominal power rail; decoupling capacitor (≥100nF) required adjacent to pin for transient suppression. |
| 5 (NC) | No Connection | Internally unconnected; must remain floating - no routing or soldering permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable switching with slow or noisy signals (e.g., mechanical switch debouncing or analog sensor thresholds). |
| Grade 1 AEC-Q100 qualification | Validated for automotive use with full PPAP support, IATF 16949 manufacturing, and extended temperature stress testing. |
| Balanced propagation delays | tPLH and tPHL match within 0.5ns typical - critical for duty-cycle preservation in clock inversion or pulse shaping. |
| Input voltage independence | Inputs functional up to 6.5V regardless of VCC - allows interfacing with higher-voltage subsystems without clamping diodes. |
| Low static current | ICC ≤ 40μA max over full temperature range - minimizes quiescent power in always-on vehicle modules. |
Applications

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 (1.65V–5.5V); lower drive (±24mA at 3.3V, but only ±8mA at 5V); non-AEC-Q100 rated. | Supports mixed-voltage systems (e.g., 3.3V MCU + 5V peripherals); unsuitable for automotive production without additional qualification. | Select when cost-sensitive industrial designs require 3.3V compatibility and AEC-Q100 is not mandated. |
| 74AHC1G04W5-7 | Same SOT25 package and pinout; identical logic function; differs in input threshold (VIH = 3.5V min at 5V) and lacks Schmitt-trigger inputs. | Requires cleaner input edges; less tolerant of noise or slow transitions; not qualified for Grade 1 automotive use. | Choose only for non-automotive 5V systems where input signal integrity is guaranteed and qualification overhead must be avoided. |
Compared with SN74LVC1G04DBVR and 74AHC1G04W5-7, the 74AHCT1G04QW5-7 uniquely combines AEC-Q100 Grade 1 qualification, Schmitt-trigger inputs, and guaranteed ±8mA drive at 5V in SOT25 - making it the sole drop-in solution for automotive signal inversion where noise immunity and temperature resilience are mandatory.

FAQ
Is the 74AHCT1G04QW5-7 pin-compatible with other SOT25 single-gate logic devices?
Yes - it shares the standard SOT25 5-pin layout (A-GND-Y-VCC-NC) with identical pin functions across Diodes' AHCT, AHC, and LVC single-gate families. Pin 5 is NC and must remain unconnected; no adaptation is needed for board reuse among these variants.
Does the Schmitt-trigger input affect propagation delay specifications?
No - propagation delay (tPD) is measured under standard conditions (VM = VCC/2) and remains ≤8.5ns at 125°C regardless of input edge rate. The Schmitt trigger only affects input threshold hysteresis (≈0.3V), not timing performance, ensuring predictable delays even with slow inputs.
Can the 74AHCT1G04QW5-7 operate reliably at 4.5V with full output drive?
Yes - electrical characteristics confirm ±8mA output drive is guaranteed at VCC = 4.5V across -40°C to +125°C. VOL remains ≤0.55V and VOH ≥3.70V under 8mA load, satisfying 5V TTL and CMOS interface requirements even at minimum supply.
What is the thermal derating requirement for continuous operation at 125°C ambient?
With θJA = 184°C/W and PD = 250mW maximum, junction temperature rise is ~46°C at 250mW. At 125°C ambient, maximum allowable power dissipation is 430mW before exceeding TJ = 150°C - well above typical ICC × VCC (≤0.275mW), confirming safe operation without heatsinking.
