Pin Assignment

LC78845Q

Although the DVDD and AVDD pins in this IC are given different names to correspond to the internal circuit structure,

they are connected internally through the circuit substrate. As a result, if different voltages are applied to these pins,

abnormal currents will flow in the chip. Since this can cause latchup, power supplies with identical voltages and identical

power-on timings must be used.
