Product details

Overview

74AHC1G04QW5-7 from Diodes Incorporated is an AEC-Q100 Grade 1 qualified single CMOS inverter gate with push-pull output, operating from 2.0V to 5.5V supply, delivering ±8mA drive at 4.5V, featuring Schmitt-trigger input for noise immunity, and rated for -40°C to +125°C ambient. It serves as a robust signal-level inversion stage in automotive body control modules.

For engineers reviewing the 74AHC1G04QW5-7 datasheet, 74AHC1G04QW5-7 pinout, 74AHC1G04QW5-7 application, or 74AHC1G04QW5-7 equivalent, key selection criteria include automotive temperature compliance, input voltage tolerance beyond V_CC, balanced propagation delay (≤7.0 ns @ 5V/50pF), ESD robustness (2 kV HBM), and SOT25 package thermal performance (θ_JA = 184°C/W).

Technical Context

The device implements a single inverting logic function (Y = A̅) using advanced AHC-series CMOS technology, with inputs tolerant up to 6.5V independent of V_CC. Its Schmitt-trigger input threshold (V_IH ≈ 3.85V, V_IL ≈ 1.65V @ V_CC = 5.5V) enables reliable operation with slow-rising signals in noisy environments.

It supports rail-to-rail output swing (V_OH ≥ 3.94V, V_OL ≤ 0.36V @ V_CC = 4.5V/8mA), exhibits balanced high/low drive strength, and maintains stable timing across temperature (t_PD = 1.0–7.0 ns over -40°C to +125°C with 50pF load).

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Inverter (Y = A̅); provides single-stage Boolean negation with standard push-pull output.
Supply Voltage Range	2.0V to 5.5V; supports mixed-voltage system interfacing (e.g., 3.3V MCU driving 5V peripherals).
Input Voltage Tolerance	-0.5V to 6.5V; allows inputs to exceed V_CC, enabling level-shifting without external components.
Output Drive Strength	±8mA @ 4.5V; sufficient to directly drive multiple 74AHC inputs or small LEDs with series resistor.
Propagation Delay	≤7.0 ns @ V_CC = 5V, CL = 50pF, -40°C to +125°C; ensures deterministic timing in real-time control loops.

Junction Temp Range	-40°C to +150°C; supports operation under hood or near power electronics with margin for self-heating.

Pinout & Package

SOT25 (3.0mm × 2.8mm × 1.2mm, 0.95mm lead pitch) surface-mount package with moisture sensitivity level 1 and matte tin-plated leads.

Pin/Terminal	Circuit Role	Design Meaning
1 (A)	Data Input	CMOS-compatible input with Schmitt-trigger hysteresis; accepts slow edges and rejects noise.
2 (GND)	Ground Reference	Return path for all internal current; must be low-impedance to minimize ground bounce.
3 (Y)	Data Output	Push-pull output capable of sourcing/sinking ±8mA; drives capacitive loads up to 50pF within spec.
4 (V_CC)	Power Supply	Primary supply rail; bypass capacitor (0.1µF) required within 5mm for stable switching.
5 (NC)	No Connection	Internally unconnected pin; must remain floating-no PCB trace or solder mask opening required.

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for -40°C to +125°C ambient operation in automotive ECUs, with PPAP documentation support.
Schmitt-trigger input	Hysteresis >0.5V @ V_CC = 5V ensures clean transitions on noisy sensor or switch inputs.
V_IN-to-V_CC independence	Inputs functional up to 6.5V regardless of V_CC setting-enables direct connection to higher-voltage sensors.
Low dynamic power	ICC ≤ 40 µA @ V_CC = 5.5V, TA = +125°C-minimizes self-heating in thermally constrained modules.
Lead-free & green construction	Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); compliant with RoHS 3 and IATF 16949 manufacturing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar single inverter gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G04DBVR	Wider V_CC range (1.65–5.5V); lower drive (±24mA @ 3.3V vs. ±8mA @ 4.5V); no Schmitt input.	Lacks input hysteresis-requires external RC filtering in noisy environments; not AEC-Q100 qualified.	Select when cost or 1.65V operation is critical and EMI environment is controlled.
MC74VHC1G04DTT1G	Same AEC-Q100 Grade 1 rating; identical SOT25 footprint; slightly higher ICC (max 100µA @ +125°C).	Compatible pinout and function but lacks Diodes' specific ESD robustness (1500V HBM vs. 2000V).	Choose for legacy design continuity where Diodes' 2kV HBM margin is not required.

Compared with SN74LVC1G04DBVR and MC74VHC1G04DTT1G, the 74AHC1G04QW5-7 uniquely combines Schmitt-trigger noise immunity, 2000V HBM ESD, and guaranteed -40°C to +125°C operation in a single-source automotive-qualified part-critical for safety-critical body electronics.

FAQ

Is the 74AHC1G04QW5-7 pin-compatible with other SOT25 single inverters?

Yes-the 74AHC1G04QW5-7 uses standard SOT25 pinout (A-GND-Y-V_CC-NC), matching industry-standard single-gate logic packages including SN74LVC1G04 and MC74VHC1G04. Pin 5 is NC and must remain unconnected; no adaptation is needed for drop-in replacement in existing SOT25 footprints.

What is the maximum capacitive load this inverter can drive while staying within propagation delay specs?

The datasheet specifies t_PD ≤ 7.0 ns at V_CC = 5V with C_L = 50pF over full temperature range. Driving >50pF increases delay nonlinearly and may cause ringing; for loads >50pF, add a series resistor (e.g., 33Ω) near the output to dampen reflections without violating VOH/VOL limits.

Can unused inputs be left floating in this device?

No-per datasheet Note 7, unused inputs must be tied to V_CC or GND. Floating inputs risk oscillation due to CMOS input structure, increasing dynamic power and potential EMI. For the 74AHC1G04QW5-7, only one input exists (Pin 1), so this applies only if the device is used in non-inverting configurations via external feedback (not recommended).

Does the NC pin require any PCB layout consideration?

Pin 5 (NC) is internally unconnected and must remain electrically floating-no trace, pad, or solder mask opening is required. Do not connect it to GND, V_CC, or any net; avoid routing signals nearby to prevent parasitic coupling, especially in high-frequency sections of the board.
