MC3488A Dual EIA423/EIA232D Line Driver The MC3488A dual is singleended line driver has been designed to satisfy the requirements of EIA standards EIA423 and EIA232D, as well as CCITT X.26, X.28 and Federal Standard FIDS1030. It is MC3488A MAXIMUM RATINGS (Note 1) Rating Symbol Value Unit Power Supply Voltages V + 15 V CC V 15 EE Output Current Source I + 150 mA O+ Sink I 150 O Operating Ambient Temperature T 0 to + 70 C A Junction Temperature Range T 150 C J Storage Temperature Range T 65 to + 150 C stg Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. Devices should not be operated at these values. The Electrical Characteristics provide conditions for actual device operation.
