DS26LS32C DS26LS32M DS26LS32AC DS26LS33C
DS26LS33M DS26LS33AC Quad Differential Line
Receivers
General Description
The DS26LS32 and DS26LS32A are quad differential line
receivers designed to meet the RS-422 RS-423 and Feder-
al Standards 1020 and 1030 for balanced and unbalanced
digital data transmission
The DS26LS32 and DS26LS32A have an input sensitivity of
200 mV over the input voltage range of g7V and the
DS26LS33 and DS26LS33A have an input sensitivity of
500 mV over the input voltage range of g15V
Both the DS26LS32A and DS26LS33A differ in function
from the popular DS26LS32 and DS26LS33 in that input
pull-up and pull-down resistors are included which prevent
output oscillation on unused channels
Each version provides an enable and disable function com-
mon to all four receivers and features TRI-STATE outputs
with 8 mA sink capability Constructed using low power
Schottky processing these devices are available over the
full military and commerical operating temperature ranges
Features
Y High differential or common-mode input voltage ranges
of g7V on the DS26LS32 and DS26LS32A and g15V
on the DS26LS33 and DS26LS33A
Y g0 2V sensitivity over the input voltage range on the
DS26LS32 and DS26LS32A g0 5V sensitivity on the
DS26LS33 and DS26LS33A
Y DS26LS32 and DS26LS32A meet all requirements of
RS-422 and RS-423
Y 6k minimum input impedance
Y 100 mV input hysteresis on the DS26LS32 and
DS26LS32A 200 mV on the DS26LS33 and
DS26LS33A
Y Operation from a single 5V supply
Y TRI-STATE outputs with choice of complementary out-
put enables for receiving directly onto a data bus
