All DC Electrical Characteristics are over the Recommended Operating Conditions with V
CC
at +5.0V +5%, unless otherwise stated.
1 For test circuit details please contact Silver Telecom
2 Typical figures are at 25°C with nominal +5V supply and 25mA loop current, unless otherwise stated. These figures are for design aid only.
3 Operating currents are dependant on the users application.
