DS34F86/DS35F86
RS-422/RS-423 Quad Line Receiver with TRI-STATE®
Outputs
General Description
The DS34F86/DS35F86 RS-422/3 Quad Receiver features
four independent receivers, which comply with EIA Stan-
dards for the electrical characteristics of balanced/
unbalanced voltage digital interface circuits. Receiver out-
puts are 74LS compatible TRI-STATE structures which are
forced to a high impedance state when the appropriate out-
put control lead reaches a logic zero condition. A PNP device
buffers each output control lead to assure minimum loading
for either logic one or logic zero inputs. In addition each re-
ceiver has internal hysteresis circuitry to improve noise mar-
gin and discourage output instability for slowly changing in-
put waveforms.
The DS34F86/DS35F86 offers improved performance due to
the use of state-of-the-art L-FAST bipolar technology. The
L-FAST technology allows for higher speeds and lower cur-
rents by utilizing extremely short gate delay times. Thus, the
DS34F86/DS35F86 features lower power, extended tem-
perature range, and improved specifications.
The DS34F86/DS35F86 offers optimum performance when
used with the DS34F87/DS35F87 Quad Line Driver.
