概述

Description

74LCX14MX is a hex inverter with Schmitt-trigger inputs from the 74LCX CMOS family. It contains six independent inverters, each with input hysteresis to convert slow or noisy signals into clean digital transitions. Key points:
- Six Schmitt-trigger inverters (one per input).
- Low-voltage operation, typically around 1.65 V to 3.6 V (check exact variant).
- CMOS input/output, low static current and rail-to-rail outputs.
- Good for debouncing, signal conditioning, clock shaping, and simple level‑shifting in mixed‑voltage systems.
MX denotes a specific packaging/grade variant (e.g., a particular 14-pin package). Check the datasheet for the exact package type and voltage/speed grades for your supplier.

Features

74LCX14MX is a hex Schmitt-trigger inverter. Key features:
- 6 independent Schmitt-trigger inverters (six NOT gates)
- Schmitt-trigger inputs for clean, noise-immune transitions
- CMOS output drivers with rail-to-rail outputs
- Low static and dynamic power
- Wide operating voltage range (typical 1.65–3.6 V; check datasheet for exact variant)
- Input range 0 to Vcc; suitable for single-supply logic
- Standard 14-pin package options (MX suffix indicates common MSOP/SOIC/DIP styles)
- Fast switching with predictable propagation delays
- ESD protection and suitability for signal conditioning, debouncing, clock distribution, and level shifting.
