temperature range, otherwise specifications are at T
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Testing done at V
Note 3: Supply current is measured with driver and receiver outputs
unloaded and the driver inputs tied high.
Note 4: Supply current and driver leakage current measurements in shut-
down are performed with V
using DRIVER DISABLE are performed with V
LT1135, LT1139, LT1140 and LT1141 with 12V supplies, V
