DS26LS32AC/DS26LS32C/DS26LS32M/DS26LS33M
Quad Differential Line Receivers
General Description
The DS26LS32 and DS26LS32A are quad differential line re-
ceivers designed to meet the RS-422, RS-423 and Federal
Standards 1020 and 1030 for balanced and unbalanced digi-
tal data transmission.
The DS26LS32 and DS26LS32A have an input sensitivity of
200 mV over the input voltage range of ±7V and the
DS26LS33 have an input sensitivity of 500 mV over the input
voltage range of ±15V.
The DS26LS32A differ in function from the popular
DS26LS32 and DS26LS33 in that input pull-up and
pull-down resistors are included which prevent output oscil-
lation 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
n High differential or common-mode input voltage ranges
of ±7V on the DS26LS32 and DS26LS32A and ±15V
on the DS26LS33
n ±0.2V sensitivity over the input voltage range on the
DS26LS32 and DS26LS32A, ±0.5V sensitivity on the
DS26LS33
n DS26LS32 and DS26LS32A meet all requirements of
RS-422 and RS-423
n 6k minimum input impedance
n 100 mV input hysteresis on the DS26LS32 and
DS26LS32A, 200 mV on the DS26LS33
n Operation from a single 5V supply
n TRI-STATE outputs, with choice of complementary
output enables for receiving directly onto a data bus
