Product details
Overview
74AHCT1G14W5-7 from Diodes Incorporated is a single-channel Schmitt-trigger inverter IC in SOT25 package, operating at 4.5V–5.5V supply, delivering ±8 mA output drive at 5.0V, with input hysteresis (ΔVT = 0.4–1.6 V) and propagation delay as low as 0.6 ns (CL = 15 pF). It enables noise-immune signal conditioning in digital interface circuits.
For engineers reviewing the 74AHCT1G14W5-7 datasheet, 74AHCT1G14W5-7 pinout, 74AHCT1G14W5-7 application, or 74AHCT1G14W5-7 equivalent, key selection criteria include input threshold voltages (VT+ = 1.9–2.1 V, VT− = 0.5–0.6 V), thermal resistance (θJA = 195 °C/W), ESD robustness (2 kV HBM), and compatibility with 5V TTL-level systems.
Technical Context
This device implements a single inverting logic gate with Schmitt-trigger input thresholds to reject slow-rising or noisy signals-VT+ = 1.9–2.1 V and VT− = 0.5–0.6 V across VCC = 4.5–5.5 V. Its push-pull CMOS output supports rail-to-rail switching with guaranteed VOH ≥ 3.7 V and VOL ≤ 0.55 V at IOL = 8 mA.
Designed for 5V logic domains, it complies with JEDEC-standard AHCT family timing and voltage levels. Input hysteresis (0.4–1.6 V) ensures reliable transition detection even with <20 ns/V input slew rates, and its low ICC (≤40 μA) and Cpd (10 pF) support energy-efficient operation in battery-sensitive nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5V TTL and CMOS systems without level-shifting. |
| Input Hysteresis ΔVT | 0.4 V to 1.6 V - Provides noise margin against signal bounce or EMI in industrial control or sensor interface lines. |
| tpd (CL = 15 pF) | 0.6 ns (min) to 9.0 ns (max) - Enables high-speed signal inversion in clock buffering or data path conditioning. |
| Output Drive | ±8 mA at 5.0 V - Sufficient to directly drive multiple 74-series inputs or small LEDs without external buffers. |
| ESD Protection | 2 kV HBM, 1 kV CDM - Meets industrial handling requirements without additional protection circuitry. |
| θJA (SOT25) | 195 °C/W - Allows operation up to +125 °C ambient in compact PCB layouts with minimal copper area. |
Pinout & Package
SOT25 (5-pin SC-74A) surface-mount package with exposed pad not present; moisture sensitivity level (MSL) 1 per J-STD-020; RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connection | Unbonded die pad - must remain unconnected to avoid parasitic coupling or latch-up risk. |
| 2 (A) | Data Input | Schmitt-trigger input accepting 0–5.5 V; hysteresis enables clean edge detection on slow analog-like signals. |
| 3 (GND) | Ground Reference | Primary return path for output current and internal biasing; requires low-impedance PCB connection. |
| 4 (Y) | Data Output | Inverted, push-pull CMOS output capable of sourcing/sinking ±8 mA while maintaining logic levels. |
| 5 (VCC) | Supply Voltage | Power rail for internal logic; decoupling capacitor (0.1 µF) required within 5 mm for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable signal recovery from slow-rising or noisy sources such as mechanical switches or RC-filtered sensors. |
| CMOS low-power operation | ICC ≤ 40 µA at 5.5 V - reduces quiescent power in always-on monitoring circuits. |
| 5V TTL-compatible output | VOH ≥ 3.7 V / VOL ≤ 0.55 V at 8 mA - ensures interoperability with legacy 74LS/74ALS loads. |
| Green molding compound | Halogen-free, Br/Sb-free package - meets IPC-1752A material declaration and environmental compliance mandates. |
Applications
| Industrial Sensor Interface | USB Host Power Control |
|---|---|
Use Scenario: Debouncing mechanical limit switches in PLC I/O modules where contact bounce exceeds 10 µs. IC Role / Device Role / Timing Role: Signal conditioner converting erratic switch transitions into clean digital edges for microcontroller GPIO capture. Use Value: Input hysteresis eliminates need for external RC filters or firmware debouncing, reducing BOM count and latency. | Use Scenario: Enabling/disabling VBUS power to downstream USB peripherals based on host controller logic state. IC Role / Device Role / Timing Role: Level-shifting inverter driving enable line of load switch (e.g., TPS229xx) from 3.3V GPIO. Use Value: Push-pull output delivers full 5V swing to ensure reliable turn-on of 5V-gate MOSFETs without pull-up resistors. |
| Legacy Bus Signal Conditioning | Audio Amplifier Mute Control |
Use Scenario: Cleaning up degraded TTL-level clock or strobe signals on aging backplane interconnects. IC Role / Device Role / Timing Role: Noise-immune inverter restoring signal integrity before feeding FPGA clock input or latch enable. Use Value: Propagation delay ≤9 ns (125°C) and low jitter preserve timing margins in synchronous bus architectures. | Use Scenario: Generating mute/unmute control for Class-D audio amplifiers triggered by slow-rising microcontroller reset signals. IC Role / Device Role / Timing Role: Inverting buffer with hysteresis preventing audible pop/click during power-up sequencing. Use Value: Guaranteed VT− = 0.5 V ensures mute activation only after reset voltage stabilizes above threshold. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AHCT1G14DBVR | Same AHCT logic family, identical electrical specs, but in SOT-23-5 (same pinout as SOT25); θJA = 216 °C/W. | Higher thermal resistance limits sustained 125°C operation in dense layouts. | Select when footprint compatibility with TI-designated boards is required; verify thermal derating. |
| 74LVC1G14GW,125 | Lower VCC range (1.65–5.5 V); VT+ = 1.1–1.4 V at 3.3 V; higher Cpd (15 pF); no 5V-tolerant inputs. | Not suitable for pure 5V-only systems; requires level translation if interfacing with 5V peripherals. | Prefer for mixed-voltage designs where 3.3V operation dominates and lower ICC (<10 µA) is critical. |
Compared with SN74AHCT1G14DBVR, the 74AHCT1G14W5-7 offers lower thermal resistance (195 vs. 216 °C/W) for improved power dissipation in space-constrained industrial modules; versus 74LVC1G14GW, it guarantees 5V-tolerant inputs and tighter VT matching for legacy 5V signal chains.

FAQ
What is the maximum operating temperature for continuous use?
The 74AHCT1G14W5-7 is rated for continuous operation from −40 °C to +125 °C ambient, with junction temperature limited to 150 °C. At maximum ambient, thermal design must ensure θJA × PD ≤ 25 °C margin; typical power dissipation is <0.5 mW at 1 MHz with CL = 15 pF.
Can this device interface directly with 3.3V microcontrollers?
Yes-the input is 5V-tolerant (VI up to 6.5 V), so a 3.3V GPIO can safely drive pin A. However, output swing is rail-to-rail (0–5V), so direct connection to 3.3V-only inputs requires a series resistor or level shifter to avoid overvoltage damage.
Is the NC pin (Pin 1) safe to connect to ground or VCC?
No-Pin 1 is internally unconnected and must remain floating. Connecting it to any potential may introduce leakage paths or parasitic capacitance, potentially degrading noise immunity or increasing propagation delay variability per DS35183 Rev. 1-2 Section 3.
Does this part support hot-swap or live-insertion?
No-74AHCT1G14W5-7 lacks hot-swap protection features such as power-up sequencing control or Ioff. Applying VCC before or after input signals may cause transient current spikes; always power VCC first and stabilize before asserting inputs per recommended operating conditions in DS35183 Section 4.
