1. Exceeding these ratings may cause permanent damage.
Functional operation under these conditions is not implied.
2. Maximum dissipation or 1 second should not be exceeded,
only one output to be tested at any one time.
3. Exposure to absolute maximum ratings for extended
periods may affect device reliablity.
4. Current is defined as positive into the device.

SCLK to DIS/DOS RELATIONSHIP
Both DIS and DOS must be synchronous to SCLK. Ideally they should both be produced from SCLK, in which case the
SCLK rising edge would either be first or coincident with the DIS and DOS rising edges.
In any event, the rising edge of SCLK must not fall between 2ns and 10ns after the rising edge of either DIS or DOS
