4) Notices on use

Note the following when replacing devices as the ASYNC pin is differently treated between the

MSM82C84A and the MSM82C84A-5/MSM82C84A-2:

Case 1: When only a pullup resistor is externally connected to.

The MSM82C84A can be replaced by the MSM82C84A-2.

Case 2: When only pulldown resistor is externally connected to.

When the pulldown resistor is 8 kiloohms or less, the MSM82C84A can be replaced by the

MSM82C84A-2.

When the pulldown resistor is greater than 8 kiloohms, use a pulldown resistor of 8 kiloohms or less.

Case 3: When an output of the other IC device is connected to the device.

ASYNC pin of the MSM82C84A-2 has an allowance of 100 mA or more.
