Hot-selling and scarce UM82C11 Printer Adapter Interface IC DIP40 spot stock

Product Descriptions

The UM82C11-C, Printer Adapter Interface (P A I), fabricated  w ith a silicon gate CMOS process, offers parallel port  interface between the CPU and the printer, and is especially  suitable as a printer adapter for industry-standard  personal computers.

The UM82C11 -C uses T T L logic to interface w ith the printer.  Printer data bus pins can each source 2.6 mA and sink  24 mA. Each of the four printer control pins can  source 1.5 mA and sink 7mA. The UM82C11-C fits the well-known Centronics printer interface.

PAI is also suitable for a personal computer interface board  which contains RS-232C interface or display interface.  The on-chip oscillator and -HO divider can be used to  offer the BAUD-rate clock w ith RS-232C interface or  the dot clock w ith monochrome display interface.

The user can use the Data Bus, IOR, IOW, IRQ, and  CS to interface PAI with 8086 or Z-80 microprocessors.
