The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T
A
= 25°C. V
CC
= 5V ±5% (Notes 2 and 3) unless otherwise noted.
Note 1: Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2: All typicals are given for V
CC
= 5V and T
A
= 25°C.
Note 3: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to device ground unless
otherwise specified.
Note 4: For higher ambient temperatures, the part may enter thermal
shutdown during short-circuit conditions.
Note 5: Both driver input and driver enable pins are pulled high
simultaneously.
Note 6: Guaranteed by design.
Note 7: Measured with an external LTC1485 driver.
