Product details

Overview

74HCT14PW,118 from Nexperia is a hex inverting Schmitt trigger IC designed for noise-immune signal conditioning in digital systems. It operates from 4.5 V to 5.5 V, features TTL-compatible input thresholds (VT+ = 1.41 V typ, VT− = 0.85 V typ at VCC = 4.5 V), 6 independent channels, and delivers jitter-free output transitions with hysteresis of 0.56 V typical-enabling reliable waveform shaping in oscillator and timing circuits.

For engineers reviewing the 74HCT14PW,118 datasheet, 74HCT14PW,118 pinout, 74HCT14PW,118 application, or 74HCT14PW,118 equivalent, this page provides verified functional identity, TSSOP14 package mapping, Schmitt-trigger transfer characteristics, propagation delay (20–34 ns at VCC = 4.5 V), and validated alternatives for wave-shaping, multivibrator, and clock-signal conditioning use cases.

Technical Context

The 74HCT14PW,118 implements six independent CMOS inverter stages, each with asymmetric Schmitt-trigger input thresholds optimized for TTL-level interfacing. Its input clamping diodes allow safe operation with input voltages exceeding VCC when current-limited.

It uses standard 74-series logic architecture with no internal feedback or programmability-functionality is fully defined by static transfer characteristics (VT+, VT−, VH) and dynamic parameters (tpd, tt) under specified load (CL = 50 pF) and supply conditions (VCC = 4.5 V).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - ensures compatibility with 5 V TTL and mixed-voltage logic systems without level shifters.
Input Threshold (VT+)	1.41 V (typ) at VCC = 4.5 V - enables clean recognition of TTL HIGH signals (≥2.0 V) with margin.
Hysteresis Voltage (VH)	0.56 V (typ) at VCC = 4.5 V - rejects noise up to ±280 mV on slow-rising/falling inputs without false triggering.
Propagation Delay	20–34 ns (tpd, nA to nY) - supports reliable operation up to ~15 MHz in relaxation oscillators or pulse edge detection.
Output Drive	±4.0 mA (IO) - sufficient to drive 10 LS-TTL loads or moderate capacitive loads (<50 pF) directly.
Operating Temperature	−40 °C to +125 °C - qualified for industrial and extended-temperature embedded control environments.
Power Dissipation	CPD = 8 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal design.

Pinout & Package

TSSOP14 plastic thin shrink small outline package (SOT402-1); 14-lead, 4.4 mm body width, 0.65 mm pitch; pin 1 index marked at corner.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Input (1A–6A)	Schmitt-triggered inverter inputs; accept slow edges and tolerate overvoltage with external current limiting.
2, 4, 6, 8, 10, 12	Output (1Y–6Y)	Inverted, rail-to-rail CMOS outputs; each drives one logic load or small capacitive node.
7	GND	Reference ground for all I/O and supply; must be low-impedance for noise immunity.
14	VCC	Primary supply rail; decoupling capacitor (100 nF) required within 5 mm for stable switching.

Key Features

Feature	Design Value
TTL-compatible input thresholds	VT+ = 1.41 V, VT− = 0.85 V at VCC = 4.5 V - eliminates need for external level translation when interfacing with legacy 5 V TTL sources.
Input clamp diodes	Enables safe interface to voltages > VCC using series resistors - supports sensor or analog front-end signal injection without damage.
Unlimited input rise/fall times	No minimum edge rate requirement - allows direct connection to RC networks, thermistors, or slow-switching mechanical contacts.
High noise immunity	0.56 V hysteresis + CMOS input structure - suppresses EMI-induced glitches in industrial wiring or motor-drive proximity.
Latch-up immunity	Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events.

Applications

Waveform Shaping

Astable Multivibrator

Use Scenario: Converting noisy or slow-rising analog sensor outputs (e.g., thermistor voltage divider) into clean digital pulses for microcontroller GPIO capture.

IC Role / Device Role: Six independent Schmitt inverters condition six separate analog channels simultaneously.

Use Value: Eliminates external comparators and hysteresis resistors, reducing BOM count and PCB area by 6× per channel.

Use Scenario: Generating precise square-wave clocks (1–100 kHz) for LED flashers, tone generators, or test signal sources using only two inverters and RC network.

IC Role / Device Role: Inverter pair forms feedback loop with resistor-capacitor timing elements.

Use Value: Stable frequency determined solely by passive component tolerances; no external crystal or timing IC required.

Monostable Multivibrator

Pulse Edge Detection

Use Scenario: Creating fixed-duration output pulses (e.g., 10–100 ms) triggered by push-button presses or limit switch closures in industrial HMI panels.

IC Role / Device Role: Single inverter stage with RC differentiator and feedback path generates timed output pulse.

Use Value: Debounces mechanical contacts and delivers consistent pulse width regardless of press duration or bounce profile.

Use Scenario: Detecting rising/falling edges of asynchronous control signals (e.g., encoder A/B phase, interrupt lines) for event counting or state machine synchronization.

IC Role / Device Role: One inverter shapes edge, another inverts delayed version to produce narrow strobe pulse.

Use Value: Converts indefinite-duration logic transitions into sub-50 ns strobes compatible with FPGA or MCU edge-triggered inputs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex inverting Schmitt trigger applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HCT14D,653	SO14 package (SOT108-1); same electrical specs but 1.27 mm lead pitch and 3.9 mm body width.	Better suited for through-hole prototyping or legacy PCBs with SOIC footprints; lower thermal resistance than TSSOP.	Select when manual soldering, rework, or higher power dissipation (>300 mW) is required.
SN74HCT14DR	Texas Instruments part; identical logic function, but VIH/VIL thresholds differ slightly (VIH min = 2.0 V vs. Nexperia's 1.4 V typ VT+).	Less tolerant of marginal TTL HIGH levels; may misread weak or high-impedance TTL sources.	Choose only if TI supply chain alignment or dual-sourcing mandates; verify input threshold margin in final design.

Compared with 74HCT14PW,118, the SO14 variant offers easier handling and better thermal performance, while the TI alternative trades threshold precision for brand diversification-neither is pin- or functionally drop-in without layout or validation adjustments.

FAQ

What is the maximum input voltage the 74HCT14PW,118 can tolerate when VCC = 5.0 V?

The device includes input clamp diodes that allow safe operation with input voltages up to VCC + 0.5 V (i.e., 5.5 V) provided input current is limited to ±20 mA via an external series resistor. Exceeding this current risks permanent damage per absolute maximum ratings.

Can the 74HCT14PW,118 drive a 100 pF capacitive load reliably?

Yes-it maintains specified propagation delay (≤51 ns) and transition time (≤22 ns) with CL = 50 pF; at 100 pF, delay increases by ~15–20% and edge rates slow, but functionality remains intact. For timing-critical paths, keep load ≤50 pF or add a buffer stage.

Does the 74HCT14PW,118 require external pull-up or pull-down resistors on unused inputs?

No-unused inputs must be tied to VCC or GND directly. Leaving them floating causes increased ICC, erratic output behavior, and potential ESD susceptibility due to undefined input state and internal parasitic paths.

How does the hysteresis of the 74HCT14PW,118 improve noise rejection compared to a standard inverter?

Its 0.56 V typical hysteresis creates distinct VT+ (1.41 V) and VT− (0.85 V) thresholds, preventing multiple output toggles when input noise crosses a single threshold. This eliminates chatter on slow or noisy signals-unlike standard inverters, which lack hysteresis and oscillate near VCC/2.
