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

Notes on Maximum Ratings

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.
