Notes

11. The Voltage on any input or I/O pin cannot exceed the power pin during power-up.

12. Industrial parts are available in CY7C09099V and CY7C09199V only.

13. See page 9 and page 10 for Load Conditions.

14. CEL and CER are internal signals. To select either the left or right port, both CE0 AND CE1 must be asserted to their active states (CE0  VIL and CE1 VIH).
