DC CHARACTERISTICS over operating ranges unless otherwise specified

Caution: The device must not be removed from (or inserted into) a socket when VCC or VPP is applied.

Notes:

1. VCC must be applied simultaneously or before VPP and removed simultaneously or after VPP

2. ICC1 is tested with OE# = VIH to simulate open outputs.

3. Minimum DC Input Voltage is –0.5. During transitions, the inputs may overshoot to –2.0 V for periods less than 20 ns. Maxi-

mum DC Voltage on output pins is Vcc +0.5 V, which may overshoot to VCC +2.0 V for periods less than 20 ns.
