USAGE PRECAUTIONS
Preventing Latch-Up
condition known "latch-up" occur when input output pins CMOS device exposed voltages higher then VCCD VCCA lower than voltage, when voltages applied device excess rated values VCCD, VccA, voltages. Latchup produces rapid increase power supply current, result thermal destruction elements. Users should take sufficient precautions ensure that absolute maximum ratings exceeded time during use.
Power Supply Pins
power supply should connected VCCD, VCCA, VDD, terminals MB88146A with impedance possible. addition, recommended that ceramic capacitors approximately connected bypass capacitors between VCCD, VCCA, terminals terminals.
