DS55107/DS75107/DS75108/DS75208
Dual Line Receivers
General Description
The products described herein are TTL compatible dual high speed circuits intended for sensing in a broad range of system applications. While the primary usage will be for line receivers of MOS sensing, any of the products may effectively be used as voltage comparators, level translators, window detectors, transducer preamplifiers, and in other sensing applications. As digital line receivers the products are applicable with the SN55109/SN75109 and mA75110/ DS75110 companion drivers, or may be used in other balanced or unbalanced party-line data transmission systems. The improved input sensitivity and delay specifications of the DS75208 make it ideal for sensing high performance MOS memories as well as high sensitivity line receivers and voltage comparators.
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 VCCa supplies or VCCa supplies that are turned off.

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 actual device operation.
Note 2. Unless otherwise specified min/max limits apply across the b55§C to a125§C temperature range for the DS55107 and across the 0§C to a70§C range for the DS75107, DS75108 and DS75208. All typical values are for TA e 25§C and VCC e 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.
