Switching Characteristics
Over recommended operating conditions, SD = 0.8V, unless otherwise specified.
Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The tables of “Electrical Characteristics” specify conditions for device operation.
Note 2: Typical values are given for V
Note 3: Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground unless otherwise
specified.
Note 4: Receiver characteristics are guaranteed for SD = 0.8V. When SD = 2.0V, receiver five (R5) is active and meets receiver parameters in SHUTDOWN (SD)
mode, unless otherwise specified.
Note 5: Generator characteristics for driver input: f = 64 kHz (128 kbits/sec), t
Note 6: Generator characteristics for receiver input: f = 64 kHz (128 kbits/sec), t
Note 7: Only one driver output shorted at a time.
Over recommended operating conditions, SD = 0.8V, unless otherwise specified.
