Electrical Characteristics, 3-V Operation (Continued) Tamb = –25°C to +85°C, VS = 2.7V to 3.3V unless otherwise specified. No. Parameters Test Conditions Pin Symbol Min. Typ. Max. Unit Type* *) Type means: A =100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter Notes: 1. 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 2. After transformation of input current into voltage |
