Specifications
Table 6.2
lists the recommended operating conditions for the L64780.
Table 6.3
lists the DC characteristics of L64780, which is produced with
the LCBG10p process. This is a 0.35-micron drawn gate length cell-
based process. Characteristics in the table are the same for any device
that has a buffer with the listed parameters.

1. For normal device operation, adhere to the limits in this table. Sustained operation of the
device at conditions exceeding these values, even if they are within the absolute maximum
rating limits, can result in permanent device damage or impaired device reliability. Device
functionality to stated DC and AC limits is not guaranteed if conditions exceed recommended
operating conditions.
