SN74LS14N, Шесть триггеров Шмитта-инверторов
The SN74LS14N is a Hex Schmitt-trigger Inverter, temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals. Each circuit functions as an inverter, but because of the Schmitt action, it has different input threshold levels for positive-going (VT+) and negative-going (VT-) signals.
• Operation from Very Slow Edges
• Improved Line-receiving Characteristics
• High Noise Immunity
