MSM82C84A-2RS/GS/JS

Differences between MSM82C84A and MSM82C84A-5/MSM82C84A-2

1) Manufacturing Process

All these devices use a 3 m Si-Gate CMOS process technology.

The chip size of these devices is same.

The chip of the MSM82C84A-5 is entirely identical to that of the MSM82C84A-2.

2) Functions

3) Electrical Characteristics

3-1) DC Characteristics

and input current (ASYNC) of the MSM82C84A.

Item

MSM82C84A

MSM82C84A-5/-2

Internal processing of ASYNC pin

Normal CMOS input pin

Input pin with built-in pull up resistor

Notes on use

The pin should have a pullup or

pulldown resistor if it is unused.

The value of pulldown resistor

(when used) is limited. (See page 3.)
