Port Timing
tv(Q) Data Output Valid Time[3] — — 200 — 200 ns tsu(D) Data Input Setup Time — 100 — 100 — ns th(D) Data Input Hold Time — 1 — 1 — μs
Interrupt Timing
tv(INT) Valid Time on pin INT — — 4 — 4 μs trec(INT) Reset Time on pin INT

— — 4 — 4 μs
Note:
1. tVD;ACK = time for acknowledgement signal from SCL LOW to SDA (out) LOW. 2. tVD;DAT = minimum time for SDA data out to be valid following SCL LOW. 3. tv(Q) measured from 0.7VCC on SCL to 50% I/O output.
