DS75115 DS9615 Dual Differential Line Receiver
General Description
The DS75115 DS9615 is a dual differential line receiver de-
signed to sense differential signals from data transmission
lines Designed for operation over military and commercial
temperature ranges the DS75115 DS9615 can typically re-
ceive
g
500 mV differential data with
g
15V common-mode
noise Outputs are open-collector and give TTL compatible
signals which are a function of the polarity of the differential
input signal Active output pull-ups are also available offer-
ing the option of an active TTL pull-up through an external
connection
Response time may be controlled with the use of an exter-
nal capacitor Each channel may be independently con-
trolled and optional input termination resistors are also
available

Note 1
``Absolute Maximum Ratings'' are those values beyond which the safety of the device cannot be guaranteed Except for ``Operating Temperature Range''
they are not meant to imply that the devices should be operated at these limits The table of ``Electrical Characteristics'' provides conditions for the actual device
operation
Note 2
Unless otherwise specified min max limits apply across the
b
55 C to
a
125 C temperature range for the DS9615M and across the 0 C to
