Silicon Chip

Reading time ( words)

The QRC 1284X2 chip is said to be the single-chip solution to IEEE 1284 parallel-port line filtering and termination. The 28-pin QSOP package uses thin film (tantalum nitride) on silicon technology. In each chip, there are reportedly 17 capacitors, 17 pull-up resistors and nine termination resistors; for each of the 17 signal lines, a diode structure provides 8 kV of ESD protection.
