L-Bus Signals (pg. 8)
-004
LOCK pin description rewritten for clarity.
2.3. Connection Recommenda-
tions (pg. 11)
-004
Changed suggested open-drain termination networks to
reflect more realistic operating conditions with reduction in
DC power consumption.
Figure 9. Typical Current vs. Fre-
quency (Hot Temp) (pg. 13)
-004
Added figure for typical power supply current at hot tempera-
ture to aid thermal analysis.
