1. Typical characteristics are at TA = 25oC.
2. Fmax = 1/tRC .
3. These are absolute values with respect to device ground and all overshoots due to system or tester notice are included.
4. Icc_Max. is 31mA(@3.0V) / 76mA(@5.0V) under 55ns operation.
5.IccsB1 is 5uA/55uA at Vcc=3.0V/5.0V and TA=70oC.
