Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Testing done at VCC = 5V and VON/OFF = 3V.
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 VON/OFF = 0.1V. Supply current measurements
using DRIVER DISABLE are performed with VDRIVER DISABLE = 3V. For
LT1135, LT1139, LT1140 and LT1141 with 12V supplies, VOUT leakage is
200µA for VOUT forced to ±25V.
Note 5: For driver delay measurements, RL = 3k and CL = 51pF. Trigger
points are set between the driver’s input logic threshold and the output
transition to the zero crossing (tHL = 1.4V to 0V and tLH = 1.4V to 0V).
Note 6: For receiver delay measurements, CL = 51pF. Trigger points
are set between the receiver’s input logic threshold and the output
transition to standard TTL/CMOS logic threshold (tHL = 1.3V to 2.4V
and tLH = 1.7V to 0.8V).
Note 7: For LT1133A/LT1137A, absolute maximum externally applied
V – = – 6.5V. Internal charge pump will drive this pin to a higher nega-
tive voltage.
Note 8: For LT1137A, 4V/µs minimum.
