DS75107 Dual Line Receiver

General Description

The product described herein is a TTL compatible dual high speed circuitintended for sensing in a broad range of system applications. While the primary usage will be for line receivers of MOS sensing, the product may effectively be used as a voltage comparator, level translator, window detector, transducer preamplifier, and in other sensing applications. As a digital line receiver the product is applicable with the SN55109/SN75109 and µA75110/DS75110 companion drivers, or may be used in other balanced or unbalanced party-line data transmission systems.

Input protection diodes are incorporated in series with the collectors of the differential input stage. These diodes are useful in certain applications that have multiple V

+ sup-

plies or V

+ supplies that are turned off.

Note 1: “Absolute MaximumRatings” are those valuesbeyond which the safety of the device cannot beguaranteed. Except for “OperatingTemperature Range” they are not meant to imply that the devices should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation.

Note 2: Unless otherwise specified min/max limits apply across the 0˚C to +70˚C range for the DS75107. All typical values are for T

25˚C and V

5V.

Note 3: All currents into device pins shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted. All values shown as max or min on absolute value basis.

Note 4: Differential input is +100 mV to −100 mV pulse. Delays read from 0 mV on input to 1.5V on output. Note 5: Only one output at a time should be shorted. Note 6: Differential input is +10 mV to −30 mV pulse. Delays read from 0 mV on input to 1.5V on output.
