NOTES:
1. INTRN or OP3 – OP7 when used as interrupt outputs.
2. The test for open-drain outputs is intended to guarantee switching of the output transistor. Measurement of this response is referenced from themidpoint of the switching signal, V
NOTE: DACKN low requires two rising edges of X1 clock after CSN is low.

. This point represents noise margin that assures true switching has occurred. Beyond this level, the effects of external circuitry and test environment are pronounced
