SN5414, SN54LS14, SN7414, SN74LS14
SDLS049C – DECEMBER 1983 – REVISED NOVEMBER 2016
SNx414 and SNx4LS14 Hex Schmitt-Trigger Inverters
1 Features
•1 Operation From Very Slow Edges • Improved Line-Receiving Characteristics • High Noise Immunity
2 Applications
• HVAC Gateways • Residential Ductless Air Conditioning Outdoor
Units • Robotic Controls • Industrial Stepper Motors • Power Meter and Power Analyzers • Digital Input Modules for Factory Automation
3 Description
Each circuit in SNx414 and SNx4LS14 functions as an inverter. However, because of the Schmitt-Trigger action, they have different input threshold levels for positive-going (VT+) and negative-going (VT–) signals.
These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.
