Notes

5.VIL(min) = –2.0V for pulse durations less than 20 ns for I < 30 mA.

6.VIH(max) = VCC+0.75V for pulse durations less than 20 ns.

7.Full device AC operation assumes a minimum of 100 µs ramp time from 0 to VCC(min) and 200 µs wait time after VCC stabilization.

8.Under DC conditions the device meets a VIL of 0.8V. However, in dynamic conditions Input LOW Voltage applied to the device must not be higher than 0.6V. This is applicable to SOIC package only. Refer to AN13470 for details.

9.Only chip enable (CE) must be HIGH at CMOS level to meet the ISB2 spec. Other inputs can be left floating.

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