Five Volt Tolerant Inputs: receivers allowed to receive a 5V signal while being supplied at 3.3V

Five Volt Tolerant Output: drivers allowed to drive external loads between 0V and 3.3V while being supplied at 3.3V having the

ability to sustain 5V signals when tristated.

These are normal Voltage and extended temperature specifications

TTL specification only; Vdd from 3.0 V to 3.6 V

Temperature Ambient from -55 to 125 degrees Centigrade

Adherence to rules in Power Pin / Pad Specifications Required

Refer to the CB45000 Standard Cell Specification for full Testing Levels and Conditions

Note 5. Buffers offered in 3, 4, 6, 8 mA TTL options
