CPC5604
ANDS-CPC5604-XXX
The CPC5604 is a single package optical Data Access
Arrangement (DAA) device in a low profile surface
mount PCMCIA compatible package. With a few exter-
nal components, the CPC5604 provides a full featured
International 56K capable solution. This device is well
suited for all 56K modems, voice mail systems, fax
machines, computer telephony applications, remote
data access, medical, and security systems. For
International compliance, external passive component
values can be changed or, the CPC5604 can be used
in conjunction with the CPC5601 Programmable Driver
for a host programmable International DAA.

Electrical Characteristics
Absolute Maximum Ratings are stress ratings. Stresses
in excess of these ratings can cause permanent damage
to the device. Functional operation of the device at these
or any other conditions beyond those indicated in the
operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum ratings
for an extended period may degrade the device and effect
its reliability.
