description
These circuits are TTL-compatible, high-speed line receivers. Each is a monolithic dual circuit featuring two independent channels. They are designed for general use, as well as for such specific applications as data comparators and balanced, unbalanced, and party-line transmission systems. These devices are unilaterally interchangeable with and are replacements for the SN55107, SN75107, and SN75108, but offer diode-clamped strobe inputs to simplify circuit design.

The essential difference between the A and B versions can be seen in the schematics. Input-protection diodes are in series with the collectors of the differential-input transistors of the B versions. These diodes are useful in certain party-line systems that have multiple VCC + power supplies and can be operated with some of the VCC + supplies turned off. In such a system, if a supply is turned off and allowed to go to ground, the equivalent input circuit connected to that supply would be as follows:
Input
A Version
This would be a problem in specific systems that might have the transmission lines biased to some potential greater than 1.4 V. The SN55107A is characterized for operation over the full military temperature range of 55°C to 125°C. The SN75107A, SN75107B, and SN75108A are characterized for operation from 0°C to 70°C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 3. All voltage values, except differential voltages, are with respect to network ground terminal. 4. Differential voltage values are at the noninverting (A) terminal with respect to the inverting (B) terminal. 5. Common-mode input voltage is the average of the voltages at the A and B inputs.

Operating free-air temperature, TA 55 125 0 70 °C The algebraic convention, in which the less positive (more negative) limit is designated as minimum, is used in this data sheet for input voltage levels only. NOTES: 6. When using only one channel of the line receiver, the strobe input (G) of the unused channel should be grounded and at least one of the differential inputs of the unused receiver should be terminated at some voltage between 3 V and 3 V. 7. The recommended combinations of input voltages fall within the shaded area in Figure 1. 8. The common-mode voltage may be as low as 4 V provided that the more positive of the two inputs is not more negative than 3 V.
