Note 1: Operation guaranteed at -40°C and +85°C but not tested.
Note 2: Parameters are guaranteed to meet all ISO 7816, GSM11-11, and EMV 2000 requirements. For the 1.8V card, the maxi-
mum rise and fall time is 10ns.
Note 3: Parameter is guaranteed to meet all ISO 7816, GSM11-11, and EMV 2000 requirements. For the 1.8V card, the minimum
slew rate is 0.05V/µs and the maximum slew rate is 0.5V/µs.
