    The hassles of board space constraints and design and layout complexities are said to be solved with the QRC 1284X2 chip, the single chip solution to IEEE 1284 parallel port line filtering and termination. Each chip contains 17 capacitors, 17 pull-up resistors and nine termination resistors, and for each of the 17 signal lines a diode structure provide 8 kV of ESD protection.
