Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Testing done at V
CC
= 5V and V
ON/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 V
ON/OFF
= 0.1V. Supply current measurements
using DRIVER DISABLE are performed with V
DRIVER DISABLE
= 3V. For
LT1135, LT1139, LT1140 and LT1141 with 12V supplies, V
OUT
leakage is
200µA for V
OUT
forced to ±25V.
Note 5: For driver delay measurements, R
L
= 3k and C
L
= 51pF. Trigger
points are set between the driver’s input logic threshold and the output
transition to the zero crossing (t
HL
= 1.4V to 0V and t
LH
= 1.4V to 0V).
Note 6: F
or receiver delay measurements, C
L
= 51pF. Trigger points
are set between the receiver’s input logic threshold and the output
transition to standard TTL/CMOS logic threshold (t
HL
= 1.3V to 2.4V
and t
LH
= 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 ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T
