54LS14 Datasheet | Texas Instruments

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 pensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.
