Horn Pattern
Note 1: See timing diagram for Horn Pattern (Figure 5-2).
2: TPCLK and TIRON are 100% production tested. All other AC parameters are verified by functional testing.
3: Typical values are for design information only.
4: Limits over the specified temperature range are not production tested, and are based on characterization
data.
