DS55107/DS75107/DS75108/DS75208
Dual Line Receivers
General Description
a
sup-
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 effec-
tively 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 bal-
anced 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.
