IS281- 4, IS281- 4GB DESCRIPTION The IS281-4 and IS281-5GB are four channel optical isolators with each channel consists of an infrared emitting diode optically coupled to an NPN silicon photo transistor. These devices belong to Isocom Compact Range of Optocouplers. FEATURES Half Pitch 1.27mm High AC Isolation voltage 3000V RMS ABSOLUTE MAXIMUM RATINGS (T = 25C) A Wide Operating Temperature Range Stresses exceeding the absolute maximum ratings can cause -55C to 110C permanent damage to the device. Exposure to absolute maximum ratings for long periods of time Pb Free and RoHS Compliant can adversely affect reliability.
