Macronix International 

effects of the printed circuit board traces on EPROM

arrays, a 4.7 uF bulk electrolytic capacitor should be

used between VCC and GND for each of the eight

devices. The location of the capacitor should be close

to where the power supply is connected to the array.

OUTPUT DISABLE

Output is disabled when OE is at logre high. When in

output disabled all circuitry is enabled. Except the output

pins are in a high impedance state(TRI-ATATE).

Note:

1. Refer to DC Characteristics. When VPP=VPPL memory contents can be read but not written or erased.

2. VID is the intelligent identifier high voltage. Refer to DC Characteristics.

3. Read operations with VPP=VPPH may access array data or the intelligent identifier codes.

4. With VPP at high voltage the standby current equals ICC+IPP(standby).

5. Refer to Table 2 for vaild data-in during a write operation.

6. X can be VIL or VIH.
