Product details
Overview
74AHC1G00W5-7 from Diodes Incorporated is a single 2-input positive NAND gate in SOT25 package, operating from 2.0 V to 5.5 V supply, delivering ±8 mA output drive at 5.0 V, with Schmitt-trigger inputs for noise immunity and CMOS low-power operation. It performs the Boolean function Y = A·B and is used in logic-level translation, signal conditioning, and enable/disable control in portable consumer electronics.
For engineers reviewing the 74AHC1G00W5-7 datasheet, 74AHC1G00W5-7 pinout, 74AHC1G00W5-7 application, or 74AHC1G00W5-7 equivalent, key selection criteria include input hysteresis margin, propagation delay under 7.0 ns (CL = 15 pF, VCC = 5 V), rail-to-rail output swing, ESD robustness (2 kV HBM), and SOT25 footprint compatibility with space-constrained PCB layouts.
Technical Context
The 74AHC1G00W5-7 implements standard TTL-compatible positive-logic NAND functionality using advanced AHC CMOS process technology. Its Schmitt-trigger inputs provide 0.3–0.5 V hysteresis across VCC = 2–5.5 V, enabling reliable operation with slow-rising or noisy signals.
It features push-pull outputs with symmetrical sourcing/sinking capability (±8 mA at 5 V), rail-to-rail VOH/VOL performance (e.g., VOL ≤ 0.55 V at IOL = 8 mA), and low ICC (≤40 μA) at VCC = 5.5 V, supporting battery-powered and thermally sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 5.5 V - supports dual-supply systems and mixed-voltage interfacing (e.g., 3.3 V MCU to 5 V peripheral) |
| Output Drive | ±8 mA at 5.0 V - sufficient to directly drive LED indicators or interface with multiple 74AHC inputs without buffering |
| Propagation Delay | 3.5 ns typ. (CL = 15 pF, VCC = 5 V) - enables use in sub-100 MHz timing-critical glue logic paths |
| Input Hysteresis | ~0.4 V typical (Schmitt-trigger) - rejects up to 400 mV of input noise without false triggering |
| ESD Rating | 2 kV HBM, 1 kV CDM - meets industrial handling requirements without external protection circuitry |
| Power Dissipation | 10 pF Cpd, <40 μA ICC - allows integration into always-on subsystems with <10 μW static power per gate |
Pinout & Package
SOT25 (5-pin SC-74A) package: ultra-compact surface-mount outline (2.8 mm × 1.6 mm × 1.1 mm), lead-free and RoHS compliant, optimized for high-density routing on 4-layer PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | First NAND operand; Schmitt-triggered for noise rejection and monotonic switching |
| B | Data Input | Second NAND operand; electrically identical to Pin A, supports wired-OR expansion |
| GND | Ground Reference | Return path for all internal logic and output current; must be low-inductance connection |
| Y | Data Output | Inverted AND result (Y = A·B); push-pull structure ensures fast rise/fall times and load driving |
| VCC | Supply Voltage | Primary power rail; decoupling capacitor (100 nF) required within 3 mm for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow or noisy signals (e.g., mechanical switch debouncing without RC filters) |
| Wide supply range (2.0–5.5 V) | Permits direct interface between 2.5 V, 3.3 V, and 5 V logic domains without level shifters |
| Low dynamic power (Cpd = 10 pF) | Reduces switching current in high-frequency clock distribution or data strobe circuits |
| High ESD immunity (2 kV HBM) | Eliminates need for external TVS diodes in handheld device front-end logic stages |
Applications
| PC Power Sequencing | USB Device Enumeration Logic |
|---|---|
Use Scenario: Controlling ATX power-good assertion after +3.3 V and +5 V rails stabilize. IC Role / Device Role / Timing Role: Dual-rail enable gate that asserts PWR_OK only when both supplies exceed thresholds. Use Value: Replaces discrete resistor-diode networks with single-gate logic, reducing BOM count and improving timing consistency. | Use Scenario: Detecting USB cable insertion by combining VBUS presence and ID pin state. IC Role / Device Role / Timing Role: NAND-based combinatorial logic generating USB device attach signal. Use Value: Schmitt inputs tolerate slow-rising VBUS during hot-plug events, preventing spurious enumeration failures. |
| Portable Audio Codec Control | Industrial Sensor Interface Conditioning |
Use Scenario: Enabling audio codec reset only when both system wake and clock-ready signals are active. IC Role / Device Role / Timing Role: Synchronized enable gate ensuring codec initialization occurs after clock stabilization. Use Value: Low ICC (<40 μA) minimizes quiescent current in battery-backed audio subsystems. | Use Scenario: Debouncing and synchronizing mechanical limit switch inputs before feeding to microcontroller GPIO. IC Role / Device Role / Timing Role: Noise-immune logic gate converting erratic switch bounce into clean digital edge. Use Value: Built-in hysteresis eliminates need for external RC filters, saving board area and component cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G00DBVR | Lower VCC min (1.65 V), higher max output drive (±32 mA), no Schmitt inputs | Preferred for 1.8 V systems; unsuitable where input noise immunity is required | Select when interfacing with 1.8 V FPGAs but avoid in noisy industrial switch interfaces |
| 74AUP1G00GW,125 | Ultra-low ICC (0.9 μA typ.), slower tpd (10.5 ns), same 2.0–5.5 V range and Schmitt inputs | Better for always-on sensor nodes; less suitable for >10 MHz signal routing | Choose for energy-constrained IoT endpoints where propagation delay is non-critical |
Compared with SN74LVC1G00DBVR and 74AUP1G00GW,125, the 74AHC1G00W5-7 uniquely balances Schmitt noise immunity, 5 V tolerance, and sub-7 ns speed-making it optimal for mixed-voltage industrial control panels requiring robust signal integrity without sacrificing timing margin.

FAQ
What is the minimum recommended bypass capacitor for 74AHC1G00W5-7?
A 100 nF ceramic capacitor placed within 3 mm of the VCC and GND pins is mandatory per Diodes Inc. layout guidelines. This suppresses high-frequency supply transients caused by fast output transitions, preventing logic glitches and ensuring tpd stability across temperature and voltage ranges.
Can unused inputs be left floating?
No. Unused inputs must be tied to VCC or GND-never left open. Floating inputs cause increased ICC, unpredictable output states, and potential thermal overstress due to partial conduction in internal CMOS stacks. The datasheet explicitly mandates termination per Note 3 in Recommended Operating Conditions.
Does 74AHC1G00W5-7 support 1.8 V operation?
No. Its absolute minimum VCC is 2.0 V, and recommended operating range starts at 2.0 V. Attempting 1.8 V operation results in undefined logic states, excessive propagation delay (>20 ns), and failure to meet VOL/VOH specifications-even if the device appears to toggle intermittently.
Is the SOT25 package compatible with reflow soldering per J-STD-020?
Yes. The SOT25 package is qualified for standard Pb-free reflow profiles (peak 260 °C, 20–40 sec above 217 °C). Diodes Inc. AP02001 pad layout and thermal relief design ensure coplanarity and void-free solder joints when using IPC-7351B-compliant footprints.
