The q denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VCC = 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 VCC = 5V and TA = 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.
