System Considerations
Switching between active and standby conditions via the Chip Enable pin may produce transient voltage excursions. Unless accommodated by the system design, these transients may exceed data sheet limits, resulting in device non-conformance. At a minimum, a 0.1 µF high frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This capacitor should be connected between the VCC and Ground terminals of the device, as close to the device as possible. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a 4.7 µF bulk electrolytic capacitor should be utilized, again connected between the VCC and Ground terminals. This capacitor should be positioned as close as possible to the point where the power supply is connected to the array.

Note: 1. NOTICE: Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Minimum voltage is -0.6V DC which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is VCC + 0.75V DC which may overshoot to +7.0V for pulses of less than 20 ns.

Rapid Programming Algorithm
A 50 µs CE pulse width is used to program. The address is set to the first location. VCC is raised to 6.5V and OE / VPP is raised to 13.0V. Each address is first programmed with one 50 µs CE pulse without verification. Then a verification reprogramming loop is executed for each address. In the event a byte fails to pass verification, up to 10 successive 50 µs pulses are applied with a verification after each pulse. If the byte fails to verify after 10 pulses have been applied, the part is considered failed. After the byte verifies properly, the next address is selected until all have been checked. OE / VPP is then lowered to VIL and VCC to 5.0V. All bytes are read again and compared with the original data to determine if the device passes or fails.
