SN74LS14D, Шесть триггеров Шмитта-инверторов [SO-14]
The SN74LS14D is a Hexagonal Schmitt-trigger Inverter with LS technology and different input threshold levels for positive-going (VT+) and negative-going (VT-) signals. This circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.
• Operation from very slow edges
• Improved line-receiving characteristics
• High noise immunity
