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.
The MSM82C84A can be replaced by the MSM82C84A-2 when the I
OL
pin of the device to drive the
ASYNC
pin of the MSM82C84A-2 has an allowance of 100
m
A or more.
