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

200

µA 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.

The q denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. (Note 2)
