s HANDLING DEVICES
1. Take Care So that the Maximum Rated Value Is Not Exceeded. (Preventing Latchup)
Latchup may occur on CMOS ICs if voltage higher than VD or lower than VS is applied to input and output pins
other than medium- and high-voltage pins or if higher than the voltage which shows on “1. Absolute Maximum
Ratings” in section “s Electrical Characteristics” is applied between VD and VS.
When latchup occurs, power supply current increases rapidly and might thermally damage elements. When
using, take great care not to exceed the absolute maximum ratings.
2. Treatment of Unused Input Pins
Leaving unused input pins open could cause malfunctions. They should be connected to a pull-up or pull-down
resistor.
3. Treatment of N.C. Pins
Be sure to leave (internally connected) N.C. pins open.
4. Treatment of Pins Connected to Pull-up/Pull-down Resistors
With neither a pull-up resistor nor a pull-down resistor connected, the pin state is determined depending on the
input level that reflects an internal resistor. When controlling the pin state, however, connect a pull-up or pull-
down resistor.
