*1) We recommend connecting large and small capacitance between VDD and VSS.

In this case, the small capacitance is equal to or more than 0.1

μF, and layout nearby LSI.

Electrical Characteristics

at VSS = 0V, VDD = 2.6 to 5.5V, Ta = -40 to +105°C

* Unless otherwise specified, the Cdrv drive frequency is fCDRV = 143kHz.
