Figure 4. Timing Characteristics of STROBE, SRCLK and DATA

DC Characteristics

DC Characteristics over Recommended Operating Range, typical at 5 °C

Notes:

1. Only applicable for STROBE output.

2. Only applicable for MSBINV input.

3. RS-422 differential line driver for DATA output.

4. RS-422 differential line receiver for SRCLK input.
