Electrical Characteristics — AC Characteristics

Unless otherwise specified, Settings 1 and 2 and the following setting conditions are required.

VCC1 = 3.0V, VCC2 = VCC3 = 12.0V, GND1 = GND2 = GND3 = 0V, VDD1 = VDD2 = 3.0V, VSS = 0V, Ta = 25°C

SW1, SW2, SW3 = A SW53, SW54, SW57 = B

SW58 = ON SW48 = OFF

V58 = 3.0V

Set the serial bus registers to the "Serial Bus Register Initial Settings". Unspecified items should be set to the

default settings.

Unless otherwise specified, measure the non-inverted outputs for TP40, TP43 and TP45.
