Conditions: (-55°C < TA < +125°C) VCC = +5.0V ± 10%

Notes:

1. Write pulse width tWPW is the time when both DS and WT are simultaneously low. Either DS

or WT may go low or return high first.

2. Write hold time:

tDH = 0 for tWPW > 450nsec

tDH = 10nsec for 50nsec < tWPW < 450nsec

3. Read pulse time tRPW is the time where both DS and RD are simultaneously low. Either DS

or RD may go low or return high first.

4. Refer to “Discrete Interrupt” text for further information.
