Special handling of static-sensitive
devices

CMOS and other high-impedance devices are subject to pos-
sible static discharge damage because of the high-impedance
levels involved. The following precautions pertain specifi-
cally to static-sensitive devices. However, since many
devices in the Model 7022 are static-sensitive, it is recom-
mended that they all be treated as static-sensitive.

1. Such devices should be transported and handled only in

containers specially designed to prevent or dissipate
static buildup. Typically, these devices will be received
in anti-static containers made of plastic or foam. Keep
these parts in their original containers until ready for
installation.

2. Remove the devices from their protective containers

only at a properly grounded work station. Also, ground
yourself with a suitable wrist strap while working with
these devices.

3. Handle the devices only by the body; do not touch the

pins or terminals.

4. Any printed circuit board into which the device is to be

inserted must first be grounded to the bench or table.

5. Use only anti-static type de-soldering tools and

grounded-tip soldering irons.

Principles of operation

The following paragraphs discuss the basic operating princi-
ples for the Model 7022 and can be used as an aid in trouble-
shooting the card. The schematic drawings of the card are
shown on drawing numbers 7021-106 and 7022-176 located
in Section 7.

Block diagram 

Figure 6-9 shows a simplified block diagram of the Model
7022. Key elements include the ROM, which contains card
ID and configuration information, matrix relay drivers and
relays, digital I/O output channel drivers, and digital I/O
input channel registers. These various elements are discussed
in the following paragraphs.
