ADVANCE INFORMATION
PI74LVC3245A
8-Bit Dual Supply Bus Transceiver
with 3-State Outputs
4
P-0.3
08/05/03
DC Electrical Characteristics (Over the Operating Range, TA= –40°C +85°C)
Notes:
5. For I/O ports, the parameter IOZ includes the input leakage current.
6. 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.
