*1 Voltage between VDD and V5.

*2 Voltages applicable to V1, V2, V3 and V4 are as follows.

V1 = VDD – 1/4 (VDD – V5)

V2 = V3 = VDD – 1/2 (VDD - V5)

V4 = VDD – 3/4 (VDD – V5)

*3 Voltages applicable to V1, V2, V3 and V4 are as follows.

V1 = VDD – 1/5 (VDD – V5)

V2 = VDD – 2/5 (VDD – V5)

V3 = VDD – 3/5 (VDD – V5)

V4 = VDD – 4/5 (VDD – V5)
