IL34C86
1
Differential line receiver.
.
Microcircuit IL34C86 consists of four
differential line receivers and is a
microcircuit that meets international
standards of data transmission RS-422,
RS-423, and it is widely used in data
transmission nets, particularly in a unit for
local loop of ATS.
Functions implemented
This device carries out comparing inputs
with low differential signal of 200mV and
gives on output full signal with load
carrying capacity of
6m, and also has
hysteresis to improve noise margin.
