Product details
Overview
74AHC14PW,118 from Nexperia is a hex inverting Schmitt trigger IC with CMOS-level inputs, 2.0–5.5 V supply range, overvoltage-tolerant inputs up to 5.5 V, and operation from –40 °C to +125 °C in TSSOP14 (SOT402-1) package. It provides noise-immune signal conditioning for clock shaping, debouncing, and waveform regeneration in mixed-voltage digital systems.
For engineers reviewing the 74AHC14PW,118 datasheet, 74AHC14PW,118 pinout, 74AHC14PW,118 application, or 74AHC14PW,118 equivalent, this device is selected for robust input hysteresis, low-power CMOS logic compatibility, precise threshold control (VT+ = 3.15 V, VT− = 1.35 V at VCC = 4.5 V), and validated use in industrial sensor interfaces and microcontroller reset conditioning circuits.
Technical Context
The 74AHC14PW,118 implements six independent Schmitt-trigger inverters with asymmetric hysteresis (VH = 1.8 V typical at VCC = 4.5 V), enabling reliable transition detection on slow or noisy signals. Its CMOS input structure supports overvoltage tolerance without external clamping, allowing direct interfacing between 3.3 V and 5 V domains.
Propagation delay is tightly controlled (tpd = 3.2 ns typ / 11.0 ns max at VCC = 5.0 V, CL = 15 pF), and static characteristics are specified across full temperature and voltage ranges - including VIH/VIL thresholds referenced to 0.5 × VCC, ensuring stable switching even under supply variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - Enables operation across 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Input Thresholds (VCC = 4.5 V) | VT+ = 3.15 V, VT− = 1.35 V - 1.8 V hysteresis ensures >2× noise margin vs. standard inverters. |
| Propagation Delay (CL = 15 pF) | 3.2 ns (typ), 11.0 ns (max) at VCC = 5.0 V - Supports >90 MHz toggle rates in clean signal paths. |
| Output Drive (VCC = 4.5 V) | ±8.0 mA - Sufficient to drive 10 LSTTL loads or 50 pF transmission lines directly. |
| Input Leakage Current | ≤2.0 μA (max, –40 °C to +125 °C) - Minimizes loading on high-impedance sources like RC oscillators. |
| Power Dissipation Capacitance | CPD = 10 pF - Enables accurate dynamic power estimation: PD = CPD × VCC² × fi × N. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Reduces need for external ESD protection in board-level designs. |
Pinout & Package
TSSOP14 (SOT402-1) package: plastic thin shrink small outline, 14 leads, body width 4.4 mm, 0.65 mm pitch, 1.2 mm max height, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Data Input (1A–6A) | Schmitt-triggered CMOS inputs tolerant to 5.5 V regardless of VCC - enables mixed-voltage translation. |
| 2, 4, 6, 8, 10, 12 | Data Output (1Y–6Y) | Inverted, rail-to-rail CMOS outputs with symmetrical sourcing/sinking capability (±8 mA). |
| 7 | GND | Ground reference for all I/O and internal circuitry; requires low-inductance connection for noise immunity. |
| 14 | VCC | Primary supply pin; decoupling capacitor (100 nF ceramic) must be placed within 5 mm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Six independent Schmitt-trigger inverters | Enables simultaneous signal conditioning of multiple asynchronous inputs (e.g., six pushbuttons or sensors) without external components. |
| Overvoltage-tolerant inputs (to 5.5 V) | Eliminates need for series resistors or clamps when interfacing 5 V sensors to 3.3 V MCUs - reduces BOM count and layout area. |
| Wide temperature range (–40 °C to +125 °C) | Validated for under-hood automotive modules, industrial PLC I/O, and outdoor telecom equipment without derating. |
| Low ICC (≤40 μA max at VCC = 5.5 V) | Supports always-on monitoring functions in battery-powered edge nodes with sub-μA sleep current budgets. |
| Latch-up immunity (>100 mA per JESD78 Class II A) | Withstands transient overcurrent events during hot-plug or ESD discharge without destructive latch-up. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AHCT14PWR | TTL-compatible inputs (VIH = 2.0 V min), slightly higher ICC (≤20 μA typ), identical pinout and package. | Better suited for 5 V-only systems with legacy TTL drivers; less tolerant of sub-2 V inputs than AHC variant. | Select when interfacing with older 5 V logic families where input threshold matching is critical. |
| MC74VHC14DT | Narrower VCC range (2.0–5.5 V same), but lower CPD (8 pF), tighter tpd distribution (2.9–9.5 ns), and enhanced ESD (HBM >4000 V). | Preferred for high-speed, low-noise applications like RF module control sequencing where jitter minimization matters. | Choose for new designs requiring lowest possible dynamic power and highest ESD resilience in compact layouts. |
Compared with SN74AHCT14PWR and MC74VHC14DT, the 74AHC14PW,118 offers optimal balance of wide-voltage flexibility, proven industrial temperature reliability, and cost-effective TSSOP packaging - making it the default choice for general-purpose Schmitt-trigger signal conditioning where mixed-supply interoperability is essential.

FAQ
What is the maximum recommended operating frequency for 74AHC14PW,118 in a relaxation oscillator configuration?
The 74AHC14PW,118 supports relaxation oscillator frequencies up to 1.2 MHz when used with R = 10 kΩ and C = 100 pF, based on measured tpd = 11.0 ns (max) and hysteresis-defined timing window. Frequency stability degrades above 500 kHz due to input capacitance (CI = 10 pF) and output loading effects - design validation at target frequency and temperature is required.
Can 74AHC14PW,118 safely interface a 5 V encoder output to a 3.3 V microcontroller GPIO?
Yes - its overvoltage-tolerant inputs accept 0–5.5 V signals irrespective of VCC (set to 3.3 V), eliminating risk of damage or logic misinterpretation. The output swing remains rail-to-rail (0–3.3 V), ensuring compatible voltage levels for the MCU. No series resistor or level shifter is needed, provided encoder source impedance is ≤1 kΩ.
How does the hysteresis voltage (VH) of 74AHC14PW,118 vary with supply voltage?
VH scales linearly with VCC: at VCC = 3.0 V, VH = 1.2 V (min); at VCC = 4.5 V, VH = 1.8 V (typ); at VCC = 5.5 V, VH = 2.2 V (max). This behavior is defined by internal resistor ratios and ensures consistent noise margin percentage (≈33–40 % of VCC) across the full operating range.
Is thermal pad soldering required for the TSSOP14 (SOT402-1) package of 74AHC14PW,118?
No - the SOT402-1 package has no exposed thermal pad. Its thermal performance relies on copper pour under pins 7 (GND) and 14 (VCC), with Ptot = 500 mW derating linearly at 7.3 mW/K above 81 °C. Standard reflow profiles per IPC-J-STD-020 are sufficient; no special thermal land is needed.
