NOTES:
2. For the lowest crosstalk, and the best composite video performance, use R
L
≥
1k
.
3. Test Level: A. Production Tested; B. Typical or Guaranteed Limit Based on Characterization; C. Design Typical for Information Only.
4. See AC Test Circuits (Figure 1 through Figure 4).
5. Excludes D1/SER OUT which is a bidirectional terminal and thus falls under the higher Output Leakage limit.
6. See Typical Performance Curves for more information.
