Electrical Characteristics
Figure 1, below provides the electrical characteristics of each Input/Output. Each
port is buffered with a 74ABT245 octal bi-directional transceiver. Each input is
capable of sinking up to 64 mA, while each output can source up to 32 mA. The
OMG-USB-DIO48 requires a 5V power source and is shipped with a 5V power
supply rated at 2.4 A.
