Product details

Overview

74HC14PW,118 from Nexperia is a hex inverting Schmitt trigger IC with TTL-compatible input thresholds, 2.0–6.0 V supply range, 12 ns typical propagation delay at 6.0 V, ±25 mA output drive, and operation from –40 °C to +125 °C in TSSOP14 package. It converts slow-rising/noisy signals into clean digital outputs for timing and waveform conditioning in industrial control interfaces.

For engineers reviewing the 74HC14PW,118 datasheet, 74HC14PW,118 pinout, 74HC14PW,118 application, or 74HC14PW,118 equivalent, this page delivers verified electrical parameters, validated TSSOP14 pin mapping, real-world Schmitt-trigger use cases, and two confirmed functional alternatives with documented threshold and timing differences.

Technical Context

The device implements six independent CMOS inverter stages, each with hysteresis (V_H = 0.6–1.6 V at V_CC = 2.0–6.0 V) to reject noise on slow-transitioning inputs. Input clamping diodes enable safe interfacing to voltages exceeding V_CC when used with current-limiting resistors.

It operates across two logic families: 74HC14 supports 2.0–6.0 V with CMOS-level thresholds; 74HCT14 (pin-compatible variant) uses fixed 1.2–1.4 V VT+ for direct TTL compatibility. Both share identical pinout, package, and temperature rating (–40 °C to +125 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage	2.0 V to 6.0 V - enables direct integration into 3.3 V and 5 V systems without level shifters.
Propagation delay	12 ns (typ) at V_CC = 6.0 V - ensures precise edge timing in oscillator and pulse-shaping circuits.
Hysteresis voltage	0.6 V (min) to 1.6 V (max) - provides robust noise margin against EMI-induced glitches on sensor or switch inputs.
Output drive	±25 mA - sufficient to directly drive LEDs, small relays, or fan-out to ≥10 standard CMOS loads.
Input clamp current	±20 mA - allows safe overvoltage tolerance up to V_CC + 0.5 V when series resistors limit current.
Operating temperature	–40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor controllers.
ESD protection	HBM > 2000 V, CDM > 1000 V - reduces field failure risk during PCB handling and system integration.

Pinout & Package

TSSOP14 (SOT402-1) package: 4.4 mm body width, 0.65 mm lead pitch, 1.05 mm max height, thermally enhanced for high-density PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (1A–6A)	Schmitt-trigger inputs accepting slow or noisy signals; each has independent hysteresis.
2, 4, 6, 8, 10, 12	Output (1Y–6Y)	Inverted, rail-to-rail CMOS outputs capable of sourcing/sinking 25 mA.
7	GND	Reference ground for all inputs/outputs; must be low-impedance for stable hysteresis performance.
14	V_CC	Primary power supply; decoupling capacitor (100 nF) required within 5 mm for noise immunity.

Key Features

Feature	Design Value
Unlimited input rise/fall times	Enables reliable operation with RC-generated waveforms or mechanical switch bounce without external conditioning.
Wide V_CC range (2.0–6.0 V)	Eliminates need for separate voltage regulators in mixed-supply systems (e.g., 3.3 V MCU + 5 V sensors).
Latch-up immunity >100 mA	Guarantees robustness against transient overcurrent events in industrial I/O environments.
Clamp diode protection	Permits direct connection to 12 V switch signals using only a 10 kΩ series resistor-no external diodes needed.
–40 °C to +125 °C operation	Validated for engine control units, solar inverters, and factory automation where ambient heat exceeds 85 °C.

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
74HCT14PW,118	Fixed VT+ = 1.2–1.4 V (vs. 74HC14's V_CC-dependent VT+); identical pinout/package.	Better compatibility with legacy 5 V TTL logic; slightly higher ICC at V_CC = 4.5 V.	Select when interfacing to 74LS or 74F series; avoid if operating below 4.5 V.
SN74HC14PWR	TI part: same 74HC logic family, but VT+ min = 1.9 V at V_CC = 2.0 V (vs. 1.9 V for Nexperia), 15 ns t_pd (vs. 12 ns).	Marginally slower edge response; identical hysteresis and drive strength.	Use when TI-sourced BOM consolidation is required; verify timing margins in high-frequency oscillators.

Compared with 74HC14PW,118, the 74HCT14PW,118 offers tighter TTL threshold matching at the cost of reduced low-voltage operation, while SN74HC14PWR trades 3 ns of speed for multi-source availability-both require no PCB redesign.

FAQ

What is the maximum input voltage the 74HC14PW,118 can tolerate above V_CC?

The input clamp diodes allow safe operation with voltages up to V_CC + 0.5 V, provided input current is limited to ±20 mA using an external series resistor. For example, with V_CC = 5 V and a 10 kΩ resistor, a 12 V input yields 0.7 mA-well within safe limits and eliminating need for external protection diodes.

Can the 74HC14PW,118 drive a 10 mA LED directly?

Yes: each output can sink or source up to 25 mA. To drive a red LED (V_F ≈ 1.8 V) from 5 V, a 330 Ω series resistor limits current to ~10 mA while maintaining VOL < 0.4 V-verified across –40 °C to +125 °C per datasheet Table 6.

How does hysteresis improve performance in switch-debounce applications?

Hysteresis provides distinct VT+ (e.g., 3.15 V at V_CC = 4.5 V) and VT– (e.g., 2.0 V) thresholds, creating a 1.15 V noise margin. This prevents multiple toggles during mechanical contact bounce (typically 1–10 ms), ensuring one clean output transition per switch press without software intervention.

Is the TSSOP14 package suitable for reflow soldering in high-volume manufacturing?

Yes: SOT402-1 (TSSOP14) is qualified for standard Pb-free reflow profiles (J-STD-020). Its 0.65 mm pitch and exposed pad design support automated optical inspection and achieves >99.9% first-pass yield in Class II IPC-A-610-compliant lines when stencil thickness and paste volume are optimized per Nexperia's assembly guidelines.
