Product details
Overview
74AHCT1G04SE-7 from Diodes Incorporated is a single CMOS inverter gate with standard totem-pole output, operating at 4.5V–5.5V supply, delivering ±8 mA drive at 5.0V, featuring Schmitt-trigger input for noise immunity, and housed in SOT353 package for space-constrained logic interfacing in consumer electronics.
For engineers reviewing the 74AHCT1G04SE-7 datasheet, 74AHCT1G04SE-7 pinout, 74AHCT1G04SE-7 application, or 74AHCT1G04SE-7 equivalent, key selection criteria include TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V), propagation delay of 6.7 ns (CL = 15 pF), low ICC of 10 µA max, and ESD robustness (2 kV HBM).
Technical Context
This device implements a single positive-logic inverter (Y = A̅) using advanced AHCT-series CMOS technology, ensuring TTL-level compatibility while maintaining low static power consumption (ICC ≤ 10 µA). Its Schmitt-trigger input provides hysteresis (typ. 0.4 V), enabling reliable operation with slow-rising/falling signals in noisy environments.
The output stage uses a push-pull totem-pole structure capable of sourcing/sinking ±8 mA at VCC = 4.5 V, supporting direct interface with standard TTL loads. Thermal resistance θJA is 371 °C/W in SOT353, requiring attention to PCB copper area for sustained switching at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with legacy 5 V TTL systems and stable operation across industrial voltage tolerances. |
| Input Thresholds | VIH = 2.0 V, VIL = 0.8 V - matches standard TTL logic levels for seamless integration without level-shifting. |
| Output Drive | ±8 mA at 4.5 V - sufficient to drive one standard TTL load (10 LS-TTL units) or multiple CMOS inputs. |
| Propagation Delay | 6.7 ns max (CL = 15 pF, VCC = 4.5 V) - enables use in sub-100 MHz clock distribution and signal conditioning paths. |
| Input Hysteresis | ~0.4 V typical - suppresses false triggering on slow or noisy control lines such as reset or enable signals. |
| ESD Protection | 2 kV HBM, 1 kV CDM - exceeds JEDEC JESD22 requirements, reducing need for external protection in handheld devices. |
| Quiescent Current | 10 µA max (–40°C to +85°C) - supports low-power standby modes in battery-backed peripherals. |
Pinout & Package
SOT353 (SC-88A) is a 5-pin, 1.25 mm × 2.1 mm surface-mount package with 0.65 mm pitch; lead-free, RoHS-compliant, and assembled with halogen-free molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connection | Internally unconnected; must remain floating or grounded per layout best practice - no routing required. |
| 2 (A) | Logic Input | Inverting data input with Schmitt-trigger action; accepts TTL-level signals and rejects noise below hysteresis threshold. |
| 3 (GND) | Ground Reference | Primary return path for output current and internal bias; requires low-inductance connection to system ground plane. |
| 4 (Y) | Logic Output | Inverted output with totem-pole drive; capable of driving capacitive loads up to 50 pF within specified timing. |
| 5 (VCC) | Power Supply | Positive supply rail (4.5–5.5 V); requires local 100 nF ceramic decoupling placed within 2 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-Compatible Input Levels | VIH = 2.0 V / VIL = 0.8 V - eliminates need for external level translators when interfacing with legacy microcontrollers or FPGAs. |
| Schmitt-Trigger Input | Hysteresis ~0.4 V - prevents chatter on debounced switches, mechanical sensors, or long trace signals without added RC filtering. |
| Low-Power CMOS Core | ICC ≤ 10 µA at 85°C - reduces thermal load and extends battery life in always-on status indicators or sensor wake-up circuits. |
| Robust ESD Rating | 2 kV HBM, 1 kV CDM - meets IEC 61000-4-2 pre-compliance for consumer product touchpoints and assembly handling. |
| Small Outline Package | SOT353 footprint (1.25 × 2.1 mm) - saves >40% board area vs. SOIC-5, ideal for ultra-compact USB peripherals and wearables. |
Applications
| USB Device Status Indicator | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving an LED indicator synchronized with USB enumeration status on a compact dongle or hub controller. IC Role / Device Role / Timing Role: Inverting logic buffer converting active-high enumeration flag to active-low LED enable. Use Value: Schmitt input rejects noise from shared USB VBUS traces; ±8 mA drive directly lights standard 2 mA LEDs without external transistor. | Use Scenario: Cleaning up slow-rising analog comparator outputs before feeding into a microcontroller GPIO interrupt pin. IC Role / Device Role / Timing Role: Noise-immune digital buffer providing clean edge transitions for precise timing-critical wake-up events. Use Value: 0.4 V hysteresis eliminates false triggers from EMI on factory floor wiring; 6.7 ns delay preserves real-time response. |
| Set-Top Box IR Receiver Interface | Portable Media Player Power Sequencing |
Use Scenario: Inverting and shaping raw 38 kHz IR demodulator output before decoding by an ARM Cortex-M0 application processor. IC Role / Device Role / Timing Role: Signal conditioner converting open-collector IR receiver output to full-swing CMOS logic compatible with MCU input. Use Value: Totem-pole output ensures fast rise/fall times (<10 ns) needed for accurate carrier detection; low ICC minimizes standby drain. | Use Scenario: Generating inverted enable signals for sequential power-up of audio codec, display driver, and flash memory in an MP3 player. IC Role / Device Role / Timing Role: Single-gate logic element implementing inversion in multi-rail power sequencing networks. Use Value: SOT353 size allows placement adjacent to PMIC pins; 4.5–5.5 V range matches main 5 V rail, avoiding extra LDOs. |
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 supply range (1.65–5.5 V); lower drive (±24 mA @ 3.3 V); no Schmitt input. | Better suited for mixed-voltage 3.3 V/5 V systems but lacks noise immunity for marginal signals. | Select when operating below 4.5 V or interfacing with 3.3 V logic; avoid where input edges are slow or noisy. |
| 74AHC1G04SE-7 | Same SOT353 package; higher VCC max (5.5 V); identical pinout; no Schmitt input; lower ICC (1 µA typ). | Lower power but reduced noise margin; requires cleaner input sources than AHCT variant. | Prefer for battery-powered applications with clean signal paths; choose AHCT version when interfacing with mechanical switches or long cables. |
Compared with SN74LVC1G04DBVR and 74AHC1G04SE-7, the 74AHCT1G04SE-7 uniquely combines TTL-compatible thresholds, Schmitt-trigger input, and 5 V-only operation - making it optimal for retrofitting legacy 5 V designs with noise resilience and minimal BOM change.

FAQ
Is the 74AHCT1G04SE-7 pin-compatible with other SOT353 single-gate logic devices?
Yes - it shares identical SOT353 pinout (NC/A/GND/Y/VCC) with Diodes' 74AHCT1Gxx series and compatible offerings from Nexperia and ON Semiconductor. Pin 1 is NC, Pin 2 is input, Pin 3 is GND, Pin 4 is output, and Pin 5 is VCC. No re-layout is needed when substituting within this family.
Can the 74AHCT1G04SE-7 operate reliably at 4.5 V with full output drive specification?
Yes - the datasheet guarantees ±8 mA output drive at VCC = 4.5 V over –40°C to +85°C, with VOH ≥ 3.70 V and VOL ≤ 0.55 V under those conditions. This ensures compatibility with TTL loads even at minimum supply voltage.
What is the purpose of the NC (No Connect) pin on the 74AHCT1G04SE-7?
Pin 1 is internally unconnected and serves no electrical function. It may be left floating or tied to GND for mechanical stability during reflow; neither connection affects logic operation. Diodes' recommended pad layout treats it as a non-soldered thermal relief pad.
Does the Schmitt-trigger input affect propagation delay measurements?
Yes - the datasheet specifies tpd values measured with input transition rates ≤20 ns/V, which aligns with Schmitt-trigger behavior. Delay remains stable across varying edge speeds, unlike standard CMOS inverters, but absolute tpd increases slightly (~0.5 ns) compared to non-Schmitt variants under identical test conditions.
