Notes

14.The voltage on any input or IO pin cannot exceed the power pin during power up.

15.Pulse width < 20 ns.

16.Industrial parts are available in CY7C026AV and CY7C036AV only.

17.VIL > –1.5V for pulse width less than 10ns.

18.fMAX = 1/tRC = All inputs cycling at f = 1/tRC (except output enable). f = 0 means no address or control lines change. This applies only to inputs at CMOS level standby ISB3.

19.Tested initially and after any design or process changes that may affect these parameters.
