DESCRIPTION
L6180/1 is an octal line receiver in a plastic DIP
or PLCC designed to meet a wide range of digital
communications requirements as outlined in the
EIA standards RS232A without additional components, as well as the low speed applications of
RS422A.
The receiver meets the CCIT recommendations
V.10, V.11, X.26and V.28 low speed applications
(below100KBS).
A low pass filter on the input starts to roll off at a
frequencyof 100KHz.
This is advancedinformation on a new product now in developmentor undergoing evaluation. Details are subject to change without notice.
