SMC34C60

The SMC34C60 provides a means of re-generating an IBM AT styple(ISA) bus from the PC printer port signals.In addition to standard(comptiable) printer ports, it supports PS/2(bi-directional), EPP, and ECP ports. Up to eighth peripherals may be daisy chained between the computer and the printer.

Features of the SMC34C60 are:(1)creates PC/AT-style bus from parallel printer port signals; (2)single chip interface to any bus capable peripheral; (3)supports standard, bi-sirectional, EPP, ECP parallel ports; (4)burst mode for improved data transfer rates; (5)afaptive interface optimizes transfer rates to paralle port characteristics; (6)digital signal filtering increases noise immunity; (7)allows daisy-chain of up to eight peripheral including standatd printer; (8)provides interrupt sharing with daisy-chained devices; (9)16-bit product IDD support.

The absolute maximum ratings of the SMC34C60 can be summarized as:(1): operaitng temperature range is 0 to 70; (2): storage tmeperature range is -55 to +150; (3): lead temperature range(soldering, 10 seconds) is +325; (4): positive voltage in any pin, with respect to ground is Vcc+0.3 V ; (5): negative voltage on any pin , with respect to ground is -0.3 V ; (6): maximum Vcc is +7 V.
