The IP-UD-E-48 digital I/O IndustryPack provides 48 flexible input/output signal lines with TTL-level
inputs and outputs. Outputs will sink up to 4 mA of continuous load current. Inputs will handle TTL
levels. Each line may be dynamically and individually configured for either input or output, providing
maximum flexibility. Inputs and outputs may be double buffered, making the IndustryPack compatible
with simulation systems requiring many inputs and outputs to be latched simultaneously.
Writing a one to any line turns off the output driver, allowing a passive pull up resistor to set the line to
a logic high. Writing a zero to any line turns on the driver, driving the line to a logic low. For input use,
a one is written to the corresponding line—this is the power up default. For output use, the binary value
desired is written to the corresponding line.
Input and output lines may double buffered by providing an external clock. A bit in the Control Register
selects the polarity of this clock, allowing inputs and outputs to be latched on either the rising or falling
clock edge. Any CMOS/TTL compatible clock source may be used.
Windows NT drivers are available.
