• Input buffer for the input pins ("I" and "IO") are set at the TTL level and the options are as follows.

(U: Having pull-up resistance, D: Having pull-down resistance, S: Schmitt trigger, R: Through rate control)

• Numbers (4, 8) in the BUF column for the output pins ('O' and 'IO') indicate Io (= 4 or 8 mA).
