Electrical Characteristics
Absolute Maximum Ratings
*NOTE:
Stresses greater than those listed under Absolute Max-
imum Ratings may cause permanent damage to the
device.This is a stress rating only and functional opera-
tion of the device at these or any other conditions
above those indicated in the operational sections of
this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect reliability.
Supply voltage (VCC-GND):............................... -0.5V to 7.0V
Input or output voltage applied: (GND - 0.5V) to (VCC + 0.5V)
Storage temperature:..................................... -65°C to +150°C

Notes: 1. CSL = CSR > 2.2V.
2. CSL = CSR > VCC - 0.2V.
3. Both ports active - Maximum frequency - Outputs open - OE = VIH.
4. One port active (f = fMAX) - Output open - One port stand-by TTL or CMOS Level Inputs - CSL = CSR > 2.2V
