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. IccsB1_MAX. is 3uA / 10uA at Vcc=3V / 5V and TA=70oC.
5. Icc_MAX. is 23mA(@3V) / 55mA(@5V) under 55ns operation.
