Preliminary
PT6880
Notes: 1. Current flowing through pull-up MOSs, excluding output drive MOS.
2. Input/Output current is not included. When the input is at an intermediate level with the
CMOS, the excessive current flows through the input circuit to the power supply. To avoid
this from happening, the input level must be fixed high or low.
