Cautions 1. Be sure to avoid direct connections among the IC device output (or I/O) pins and between

VDD or VCC and GND. However, open-drain pins and open collector pins can be directly

connected. A direct connection to an external circuit can be made to avoid conflicting

output from high-impedance pins if the external circuit is designed for the correct timing.

2. If the absolute maximum rating for any of the above parameters is exceeded even

momentarily, it may adversely affect the quality of this product. In other words, these

absolute maximum ratings have been set to prevent physical damage to the product. Do

not use the product in such a way as to exceed any of these ratings.

The ratings and conditions shown below for DC characteristics and AC characteristics

are within the range for normal operation and quality assurance.
