PCA9512A_3

• Section 8.7 “Resistor pull-up value selection”, 2nd paragraph, 1st sentence changed from

“... always choose RPU ≤ 16 kΩ for VCC = 5.5 V maximum, RPU ≤ 24 kΩ for VCC = 3.6 V

maximum.” to “... always choose RPU ≤ 65.7 kΩ for VCC = 5.5 V maximum, RPU ≤ 45 kΩ for

VCC = 3.6 V maximum.”

• Figure 5 “Bus requirements for 3.3 V systems” updated:

– changed from “rise time > 300 ns” to “rise time = 300 ns”

– changed from “rise time < 20 ns” to “rise time = 20 ns”
