DS75115/DS9615 Dual Differential Line Receiver
General Description
Features
Y
Single 5V supply
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 500 mV differential data with 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.
