The q denotes the specifications which apply over the full operating
temperature range.
Note 1: Both VS pins (10, 14) must be connected together, and both
ground pins (1, 5) must be connected together.
Note 2: For junction temperatures greater than 110°C, a minimum
load of 1mA is recommended.
Note 3: The other channel is programmed to the 0V mode (XEN0 =
XEN1 = 0V) during this test.
Note 4: The VCC sense threshold voltage tests are performed
independently.
Note 5: The VPPVALID tests are performed independently.
