The q denotes specifications which apply over the full operating
temperature range.
Note 1: Absolute maximum ratings are those values beyond which the
safety of the device cannot be guaranteed.
Note 2: 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 3: All typicals are given at VCC = VDD (LTC1321/LTC1322) = 5V,
VEE = 鈥� 5V, and TA = 25掳C.
Note 4: Short-circuit current for RS485 driver output low state folds back
above VCC. Peak current occurs around VO = 3V.
