概述

Description

SN74HC14PW is a hex Schmitt-trigger inverter in a PW package. Key points:
- Six independent inverters with Schmitt-trigger inputs (hysteresis), improving noise immunity for slow or noisy signals.
- Part of the 74HC CMOS family: fast, low-power, Vcc typically 2–6 V.
- PW package denotes a 14-pin Plastic Small Outline (surface-mount) variant.
- Applications: debouncing mechanical switches, RC oscillators, waveform shaping, signal conditioning.
- Electrical basics: input tolerant from 0 up to Vcc; outputs drive a few milliamps; use proper decoupling and respect Vcc range.
- For exact specs (threshold voltages, VOH/VOL, propagation delays), consult the TI SN74HC14PW datasheet.
In short: a convenient, noise-immune hex inverter for clean digital signals in a compact SMT package.

Features

SN74HC14PW features:
- Six independent Schmitt-trigger inverters
- Schmitt-trigger inputs with hysteresis for noise/imperfect signals
- Wide operating supply: 2 V to 6 V (CMOS HC family)
- High-speed CMOS performance with low static/dynamic power
- Standard CMOS logic levels for buffering and signal conditioning
- Adequate output drive for common logic loads
- 14-pin plastic Small-Outline Package (PW suffix denotes the packaging)
Ideal for debouncing, level conditioning, and noisy signal conditioning in mixed-signal designs.

Package

A 14‑pin plastic Small Outline package (SOIC) with gull‑wing leads.

Pinout

- Pin count: 14 pins
- Function: Hex Schmitt-trigger inverter — six independent inverting stages with Schmitt-trigger inputs (A1→Y1, …, A6→Y6).

Manufacturer

Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and other electronic components.

Application

SN74HC14PW is a hex Schmitt-trigger inverter (six inverters with hysteresis). Typical uses:
- Debouncing mechanical switches/buttons
- Conditioning slow or noisy signals for microcontrollers or logic
- RC networks for oscillators and pulse shaping
- Edge detection and clean clock/pulse generation
- Noise-immune level shifting in mixed-signal circuits
(Note: PW refers to the package type; function remains the same.)

Equivalent

SN74HC14PW is TI’s 6-channel Schmitt-trigger inverter in a DIP-14 package. Equivalents (same function) include:
- 74HC14 family parts from other vendors (e.g., 74HC14N/74HC14D/74HC14W)
- Schmitt-trigger variants such as 74HCS14
- TTL-input version 74HCT14
- Older CMOS equivalents like 74AC14 / 74F14
In short: any 6-channel Schmitt-trigger inverter in the 74xx14 family from TI, NXP, Onsemi, ST, etc.
