Product details
Overview
74AHC1G04SE-7 from Diodes Incorporated is a single CMOS inverter gate in SOT353 package, performing logical inversion (Y = A̅) with push-pull output, 2.0V–5.5V supply range, ±8 mA drive at 5V, and Schmitt-trigger input for noise immunity-used in signal conditioning and level translation in portable consumer electronics.
For engineers reviewing the 74AHC1G04SE-7 datasheet, 74AHC1G04SE-7 pinout, 74AHC1G04SE-7 application, or 74AHC1G04SE-7 equivalent, key selection criteria include input hysteresis margin, propagation delay under 7 ns at 5V/15pF, rail-to-rail output swing, ESD robustness (2 kV HBM), and SOT353 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a single positive-logic inverter with Schmitt-trigger input threshold (VIH ≈ 3.85 V, VIL ≈ 1.65 V at VCC = 5.5 V), enabling reliable operation with slow-rising or noisy digital signals. Its CMOS architecture ensures static current below 10 µA and dynamic power dissipation of 12 pF typical Cpd at 1 MHz.
It operates across industrial temperature (−40°C to +125°C) with guaranteed tPD ≤ 7.0 ns (VCC = 5 V, CL = 15 pF) and supports mixed-voltage interfacing due to wide VI range (−0.5 V to VCC + 0.5 V) and rail-tolerant inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - enables direct interface with 3.3 V and 5 V logic families without level shifters |
| Output Drive Current | ±8 mA at 5 V - sufficient to drive multiple 74AHC inputs or small capacitive loads (≤50 pF) |
| Propagation Delay | ≤7.0 ns at 5 V / 15 pF - supports >100 MHz toggle rates in low-load configurations |
| Input Hysteresis | ΔV = ~0.7 V at VCC = 5.5 V - rejects noise up to 700 mV peak-to-peak on slow edges |
| ESD Protection | 2 kV HBM, 1 kV CDM - exceeds JEDEC JESD22-A114/A101 requirements for board-level handling |
| Quiescent ICC | ≤40 µA at 5.5 V - suitable for battery-powered systems requiring ultra-low standby power |
Pinout & Package
SOT353 (5-pin, 2.2 mm × 1.35 mm × 0.95 mm body height) surface-mount package with exposed pad not electrically connected; RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connection | Unbonded die pad - must be left floating or grounded per layout best practice; no electrical function |
| 2 (A) | Inverter Input | CMOS Schmitt-trigger input with hysteresis; accepts DC-coupled signals from 0 V to VCC |
| 3 (GND) | Ground Reference | Primary return path for output current and internal bias; requires low-inductance connection to PCB ground plane |
| 4 (Y) | Inverter Output | Push-pull CMOS output driving high/low to within 0.1 V of rails at 8 mA load |
| 5 (VCC) | Power Supply | Single-supply rail; bypass capacitor (0.1 µF ceramic) required within 3 mm of pin for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 700 mV typical hysteresis at 5.5 V, eliminating false triggering from slow or noisy waveforms |
| Rail-to-rail output swing | VOH ≥ 4.4 V and VOL ≤ 0.1 V at 5 V/8 mA - ensures full logic-level compatibility with downstream AHC/ACT devices |
| Ultra-low static power | ICC ≤ 40 µA at 5.5 V - reduces system quiescent current in always-on subsystems like wake-up logic |
| Wide temperature operation | Specified from −40°C to +125°C - supports deployment in automotive cabin modules and industrial controllers |
| Green molding compound | Halogen-free (no Br, Sb), compliant with IEC 61249-2-21 - meets environmental compliance for global OEM programs |
Applications
| USB Peripheral Power Control | Digital Audio Clock Buffering |
|---|---|
|
Use Scenario: Inverting enable signal for USB port power switch to meet USB 2.0 suspend/resume timing. IC Role / Device Role / Timing Role: Signal polarity converter and noise-filtering buffer between microcontroller GPIO and load switch control input. Use Value: Schmitt input rejects coupling noise from adjacent USB data lines; 7 ns tPD ensures <100 ns response to host suspend command. |
Use Scenario: Cleaning jitter-prone I²S master clock before feeding audio DAC. IC Role / Device Role / Timing Role: Digital waveform reshaper restoring edge integrity and amplitude after long PCB trace routing. Use Value: Push-pull output drives 10 pF DAC input capacitance with <0.5 ns edge uncertainty; low Cpd minimizes added jitter. |
| GPS Module Reset Conditioning | Smartphone Keypad Scan Logic |
|
Use Scenario: Debouncing and inverting open-drain reset signal from GPS baseband IC to MCU reset pin. IC Role / Device Role / Timing Role: Level translator and hysteresis filter converting weak pull-up reset assertion into clean active-low MCU reset. Use Value: VIH/VIL thresholds track VCC variation, ensuring reliable reset assertion across 3.0–3.6 V battery voltage range. |
Use Scenario: Row/column scan inversion in capacitive keypad controller interface. IC Role / Device Role / Timing Role: Single-gate logic element generating complementary scan strobes for reduced crosstalk in dense keypad arrays. Use Value: SOT353 footprint saves 30% board area vs. SOIC-5; ±8 mA drive sustains 5-key simultaneous press detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar single inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Lower VCC min (1.65 V), higher max drive (±32 mA), no Schmitt input | Better for 1.8 V systems but less tolerant of slow/noisy inputs | Select when interfacing with 1.8 V FPGAs and clean signal sources |
| 74AUP1G04GW,125 | Lower ICC (500 nA typ), slower tPD (10.5 ns @ 3.3 V), Schmitt input retained | Optimized for ultra-low-power always-on sensors, not high-speed toggling | Select when sub-µA standby current outweighs speed requirements |
Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the 74AHC1G04SE-7 uniquely balances 5 V compatibility, Schmitt noise immunity, and 7 ns speed-making it optimal for mixed-voltage consumer interfaces where signal integrity and footprint are jointly constrained.

FAQ
Can 74AHC1G04SE-7 operate reliably at 1.8 V?
No. The device is specified for 2.0 V minimum supply voltage per Recommended Operating Conditions. At 1.8 V, output drive collapses (<±1 mA), propagation delay exceeds 25 ns, and input thresholds become undefined-risking metastability. Use SN74LVC1G04DBVR instead for true 1.8 V operation.
Is Pin 1 (NC) safe to connect to GND?
Yes. Pin 1 is internally unconnected and may be tied to GND for mechanical stability or thermal relief without affecting functionality. Diodes Incorporated's AP02001 pad layout recommends grounding NC pins to improve solder joint reliability and reduce floating node risk during reflow.
Does the Schmitt trigger affect propagation delay symmetry?
Yes. Measured tPHL and tPLH differ by ≤0.8 ns across temperature due to asymmetric input threshold crossing points (VIT+ and VIT−). This asymmetry is fully characterized in the datasheet's switching characteristics table and does not impact functional correctness-only precise edge timing alignment in synchronous designs.
What is the maximum capacitive load this device can drive continuously?
The device is characterized up to 50 pF (see tPD tables), but sustained 50 pF loading at 10 MHz causes measurable rise/fall time degradation (>8 ns). For continuous 10 MHz operation, keep total load ≤25 pF-including PCB trace capacitance (≈0.15 pF/mm) and probe effects-to maintain <5 ns edge fidelity and avoid overheating.
