Applications

 Parallel Ports of PCs, printers, peripherals, and Set-Top Boxes Product Description The PACSZ1284 combines EMI filtering, ESD protec- tion, and signal termination in a single QSOP package for parallel port interfaces complying to the IEEE 1284 standard. The PACSZ1284 provides a complete parallel port ter- mination solution. It integrates the equivalent of 60 dis- crete components, making it ideal for space critical applications. The pins of the device which connect to the parallel port are protected to 30kV contact dis- charge, well beyond Level 4 of the IEC 61000-4-2 specification. All other pins are ESD-protected for con- tact discharges up to 8kV per IEC 61000-4-2. There are three available values for pull-up resistor R1. For the P ACSZ1284-01, R1 = 1kΩ; for the P ACSZ1284- 02, R1 = 2.2kΩ; for the PACSZ1284-04, R1 = 4.7kΩ. P/Active ® technology provides high reliability and low cost through manufacturing efficiency. the PACSZ1284 is silicon-based and has the same reliability character- istics as today’s integrated circuits. R1 = 1kΩ R2 = 33Ω C = 150pF PACSZ1284-02 R1 = 2.2kΩ R2 = 33Ω C = 150pF PACSZ1284-04 R1 = 4.7kΩ R2 = 33Ω C = 150pF C C C C 28 27 C C C C C C C C C C C C C

PACSZ1284 Application Information (continued) Table 2 provides the IEEE 1284 signal assignments for the three connectors, and example PACSZ1284 pin connections. When connecting a 1284-A host to a 1284-B periph- eral, the “Peripheral Logic High” signal is not used. Similarly, when a 1284-A host is connected to a 1284- C peripheral, the “Peripheral Logic High” and “Host Logic High” are not used. These two signals are optionally used to detect a “Power Off” or “Cable Dis- connect” state for host and peripheral, respectively.
