SUPER 1284
Application Information
The IEEE 1284 specification requires both termination and EMI filtering on a total of 17 signal lines. Control and Status
lines (8 in total) only require a pull-up resistor and a filter capacitor. The Data lines and Strobe also require a series
termination resistor in addition to the pull resistors and filter capacitors. See Table 1 and Schematic Diagram.
Table 1
IEEE 1284 defines three interface connectors:
- 1284 A is a 25-pin DB series connector which is the defacto PC standard for the host connection.
- 1284 B is a 36-pin, 0.085 inch centerline connector used on the peripheral device.
- 1284 C is a new 36-pin, 0.050 inch centerline connector which can be used for both host and peripheral.
Figure 1 shows a possible hook-up between the 1284-A connector on a PC motherboard and the Super 1284, illustrating
how the pin configuration of the Super 1284 allows for easy interconnects between the two. The dotted I/O signals of the
Super 1284 will typically be connected to a Super I/O chip on the motherboard.
Figure 2 shows a possible hook-up between the 1284-B connector on a peripheral and the Super 1284.
Figure 3 shows a possible hook-up between the 1284-C connector and the Super 1284.
