Cautions 1. Do not make direct connections of the output (or input/output) pins of the IC product with each
other, and also avoid direct connections to V
DD
, V
CC
or GND. However, the open drain pins or
the open collector pins can be directly connected with each other. For the external circuit
designed with the timing specifications so that any collision of the outputs from the pins subject
to high-impedance state may be prevented, direct connection can be also made.
2. Product quality may suffer if the absolute maximum ratings are exceeded for even a single
parameter, or even momentarily. In other words, the absolute maximum ratings are rated values
at which the product is on the verge of suffering physical damage, and therefore the product
must be used under conditions which ensure that the absolute maximum ratings are not
exceeded. The normal operation and reliability of the product can be only assured with the
specifications and the conditions indicated as the DC and AC characteristics.
