)
• Best suited to digital signals
• Schmitt Trigger Input (Hysteresis > 1V)
• „0“ = Low Level to 1.25V
• „1“ = High level from 3V (+/- 15%)
• Min. Pulse width: 5μs
• NO DC- decoupling

• DC- decoupling
• The Trigger level automatically adapts itself to the input signal in the range
+28.5mV to +2V. The Adaptive Trigger improves the signal to noise immunity
e.g. where electromagnetic sensors are used.
