NOTE 2

1209 F03.1

Notes: 1. If OE# is High during the Write cycle, the outputs will remain at high impedance.

2. If BES# goes Low coincident with or after WE# goes Low, the output will remain at high impedance.

If BES# goes High coincident with or before WE# goes High, the output will remain at high impedance.

Because DIN signals may be in the output state at this time, input signals of reverse polarity must not be applied.
