*) Type means: A =100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter
Notes: 1. Depending on version, see “Ordering Information”
2. BER = bit error rate; e.g., BER = 5% means that with P = 20 at the input pin 19...21 pulses can appear at the pin OUT
3. After transformation of input current into voltage
