3. System Considerations
Switching under active conditions may produce transient voltage excursions. Unless accommo-
dated by the system design, these transients may exceed datasheet 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
V CC and Ground terminals of the device, as close to the device as possible. Additionally, to sta-
bilize 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 V CC and Ground termi-
nals. This capacitor should be positioned as close as possible to the point where the power
supply is connected to the array.

5. Absolute Maximum Ratings*
Temperature under Bias ................................ -55°C to +125°C
Storage Temperature ..................................... -65°C to +150°C
Voltage on Any Pin with
Respect to Ground .........................................-2.0V to +7.0V (1)
Voltage on A9 with
Respect to Ground ......................................-2.0V to +14.0V (1)
V PP Supply Voltage with
Respect to Ground .......................................-2.0V to +14.0V (1)
*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age 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.
Note:
1. Minimum voltage is -0.6V DC which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is
V CC + 0.75V DC which may overshoot to +7.0V for pulses of less than 20 ns.
