6.4 DC Electrical Specications
(TA = 0°C to 70°C, VDD = 5V±5%; VDD.PAD = 5V±5%, or VDD.PAD = 3.3V±10%)
Notes:
(1)Programmable Output Voltage-level set to TTL.
(2)Programmable Output Voltage-level set to CMOS and no additional pull-up current.
(3)These parameters are guaranteed but not tested in production.
(4)Transient currents of 250 A are required to pull I/O Ports from logic high to logic low.
(5)Transient currents of 650 A are required to pull input pins from logic high to logic low.
(6)No more than one output should be tested at a time and the duration of the test should be less than one second.
(7) Not Applicable.
