Notes:
1. VCC must be applied simultaneously or before VPP, and removed simultaneously or after VPP.
2. Caution: The Am27C256 must not be removed from (or inserted into) a socket when VCC or VPP is applied.
3. ICC1 is tested with OE = VIH to simulate open outputs.
4. Minimum DC Input Voltage is –0.5 V. During transitions, the inputs may overshoot to –2.0 V for periods less than 20 ns.
Maximum DC Voltage on output pins is VCC + 0.5 V, which may overshoot to VCC + 2.0 V for periods less than 20 ns.
