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 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,
SN55108, 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 may have multiple V
CC+
power supplies and may be operated with some of
the V
CC+
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
Input
B Version
This would be a problem in specific systems that might possibly have the transmission lines biased to some
potential greater than 1.4 V.
The SN55107A, SN55107B, SN55108A, and SN55108B are characterized for operation over the full military
temperature range of –55
°
C to 125
°
C. The SN75107A, SN75107B, SN75108A, and SN75108B are
characterized for operation from 0
°
C to 70
°
C.
