PRODUCT OVERVIEW
The NM485D6S5MC is a low power electrically
isolated differential driver and receiver designed
for bi-directional data communication or multipoint
bus transmission. The device combines a tri-state
differential line driver and a differential input line
receiver. The driver and receiver have active high
and active low enables, respectively, which can be
connected together to function as direction control.
No external components are needed as a single
5V supply powers all functions either side of the
isolation boundary. NM485D655MC also provides
a regulated 5V, unregulated 6V and -6V isolated
supply’s for system use.

1. Components are supplied in tape and reel packaging, please refer to tape and reel specification section. Orderable part numbers are
NM485D6S5MC-R7 (80 pieces per reel), or NM485D6S5MC-R13 (350 pieces per reel).
2. VCM is the common-mode potential difference between the logic and bus sides. The transient magnitude is the range over which the
common mode is slewed. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
