Notes: 1. Measured relative to GND
2. Applies to pins M/S, OSC, OSC1, OSC2, DB7 to DB0, RD, WR, CS, RS, RES, CL1, M, FLM
3. Applies to pins V1O, V2O, V3O, V4O and V5O
4. If the LSI is used beyond its absolute maximum rating, it may be permanently damaged.
It should always be used within the limits of its electrical characteristics to prevent malfunction or
unreliability.
