• Fail-Safe bidirectional buffers
1) N-channel open-drain type
2) Tri-state type
Notes *1: V
Notes * V
As with tri-state output buffers, this type of cell also cannot be tied high to 5 V by
adding pull-up resistors external to the standard cell.

** For N-channel open-drain bidirectional buffers, in addition to those listed in Table 9-4-3, the use
of bidirectional buffers without test pins may be considered. If the use of such bidirectional
buffers is desired, contact Seiko Epson or its distributor.
