PACS1284

Application Information

Termination Considerations

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 resis-

tor and a filter capacitor. The Data lines and Strobe

also require a series termination resistor in addition to

the pull-up resistors and filter capacitors. See Table 1,

in conjunction with the schematic diagram on page 1.

Interfacing to IEEE 1284 Connectors

IEEE 1284 defines three interface connectors:

•

1284 A is a 25-pin DB series connector which is

the de facto 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 con-

nector which can be used for both host and periph-

eral.

Figure 2A shows a possible hook-up between the

1284-A connector on a PC motherboard and the

PACS1284, illustrating how the pin configuration of the

PACS1284 allows for easy interconnect between the

two. The dotted I/O signals of the PACS1284 will

typically be connected to a Super I/O chip on the

motherboard.

Figure 2B shows a possible hook-up between the

1284-B connector on a peripheral and the PACS1284.

Figure 2C shows a possible hook-up between the

1284-C connector and the PACS1284.
