概述

Description

74HC14PW is a hex Schmitt-trigger inverter from the 74HC CMOS family. It contains six independent inverting gates with Schmitt-trigger inputs, giving hysteresis for clean switching of noisy or slowly varying signals.
Key points:
- Operation: 2–6 V supply (typical 5 V).
- Features: six SCHMITT-trigger gates, high input impedance, CMOS output drivers.
- Performance: fast switching with propagation delays in the tens of nanoseconds range (depends on Vcc and load).
- Package: PW suffix denotes a 14-pin plastic surface-mount package (SOP-like). Pinout is one input per gate (1A→1Y, …, 6A→6Y); power pins are Vcc and GND per device datasheet.
Common uses:
- Debouncing switches, waveform shaping, RC oscillators.
- Conditioning slow/noisy signals for CMOS logic downstream.
- Level shifting within the HC voltage range.
Note: Specs (thresholds, exact tpd, and pinouts) vary by manufacturer and exact PW variant, so consult the vendor datasheet for your part.

Features

74HC14PW is a hex Schmitt-trigger inverter (six independent inverters) in a 14-pin plastic package (PW). Key features:
- Six Schmitt-trigger inverters for clean switching of noisy or slowly changing signals
- Wide operating supply: 2 V to 6 V (typical at 5 V)
- CMOS device: low static and dynamic power, high fan-out capability
- Rail-to-rail output stages; suitable for driving standard CMOS/TTL loads
- Fast switching: propagation delay in the low tens of nanoseconds (depends on Vcc and load)
- Low input leakage and good noise margins due to hysteresis
- Ideal for debouncing, waveform shaping, oscillators, and level shifting
- Package: 14-pin plastic package (PW variant); alternative package types may be available
Note: exact electrical parameters (VIT+, VIT−, tpd, Icc) vary by supplier and device lot; consult the specific datasheet for precise numbers.

Package

Plastic DIP (PDIP), 14-pin through-hole package. The “PW” family variant indicates plastic DIP packaging, with “118” likely a lot/date code.

Pinout

Pin count: 14 pins.
Function: 74HC14PW is a hex Schmitt-trigger inverter (six independent inverting gates with hysteresis) in the HC logic family. Vcc on pin 14, GND on pin 7; inputs on pins 1,3,5,9,11,13 and outputs on pins 2,4,6,8,10,12.
