PPC34C60 General Description

The PPC34C60 provides a means of re-generating an IBM AT style (ISA) bus from the PC printer port signals. In addition to Standard (Compatible) printer ports, the PPC34C60 supports PS/2 (bi-directional), EPP, and ECP ports. Up to eight peripherals may be daisy chained between the computer and the printer. Printer operation is unaffected.

The PPC34C60 performs as an intelligent data mux. It multiplexes the printer port signals between the daisy chain (pass-through) outputs and there-generated ISA bus. Furthermore, it handles breaking up 8- and 16-bit ISA data into 4- or 8-bit chunks for the parallel port.

The PPC34C60 also provides a piezo transducer driver for battery-powered systems. The transducer will signal low battery with two repeated beeps. If the cable to the computer is disconnected, or if the host is dormant for about a minute, the transducer will signal inactivity with four beeps. Additionally, a power-down signal can be provided to external circuitry to automatically shut down system power during inactivity.
