MB88146A
s USAGE PRECAUTIONS
1. Preventing Latch-Up
A condition known as “latch-up” may occur when the input or output pins of a CMOS IC device are exposed to
voltages higher then VCCD or VCCA or lower than GND voltage, or when voltages are applied to the device in
excess of rated values for VCCD, VccA, or VDD to GND voltages. Latchup produces a rapid increase in power
supply current, and may result in thermal destruction of elements. Users should take sufficient precautions to
ensure that absolute maximum ratings are not exceeded at any time during use.
2. Power Supply Pins
The power supply should be connected to the VCCD, VCCA, VDD, and GND terminals of the MB88146A with as
low an impedance as possible.
In addition, it is recommended that ceramic capacitors or approximately 0.1 µF be connected as bypass
capacitors between the VCCD, VCCA, and VDD terminals and the GND terminals.
