P-0.2
08/11/03
ADVANCE INFORMATION
DC Electrical Characteristics (Over Supply Voltage and Operating Temperature Ranges, unless otherwise specified)
B-Port (3.3V)
Notes:
5. All typical values are measured at VCCB = 3.3V, TA = 25°C
6. For I/O ports, the parameter IOZ includes the input leakage current.
7. This is the increase in supply current for each input that is at one of the specified voltage levels, rather than 0V or the associated VCC.

Notes:
7. CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (ICCD) at no
output loading and operating at 50% duty cycle, CPD is related to ICCD dynamic operating current by the expression:
ICCD = (CPD)(VCC)(fIN) +(ICC static)
