•

See "List of Pin Functions" and "I/O Circuit Type" about +B input available pin.

•

Use within recommended operating conditions.

•

Use at DC voltage (current) the +B input.

•

The +B signal should always be applied a limiting resistance placed between the +B signal and the device.

•

The value of the limiting resistance should be set so that when the +B signal is applied the input current to the device pin

does not exceed rated values, either instantaneously or for prolonged periods.

•

Note that when the device drive current is low, such as in the low-power consumpsion modes, the +B input potential may

pass through the protective diode and increase the potential at the VCC and AVCC pin, and this may affect other devices.

•

Note that if a +B signal is input when the device power supply is off (not fixed at 0 V), the power supply is provided from

the pins, so that incomplete operation may result.

•

The following is a recommended circuit example (I/O equivalent circuit).

WARNING:

−

Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature, etc.) in excess

of absolute maximum ratings. Do not exceed these ratings.
