FEATURES
DESCRIPTION
The DS26LS32 and DS26LS32A are quad differential
line receivers designed to meet the RS-422, RS-423
and Federal Standards 1020 and 1030 for balanced
and unbalanced digital data transmission.

•
High Differential or Common-Mode Input
Voltage Ranges of ±7V on the DS26LS32 and
DS26LS32A and ±15V on the DS26LS33
•
•
±0.2V Sensitivity Over the Input Voltage Range
on the DS26LS32 and DS26LS32A, ±0.5V
Sensitivity on the DS26LS33
The DS26LS32 and DS26LS32A have an input
sensitivity of 200 mV over the input voltage range of
±7V and the DS26LS33 has an input sensitivity of
500 mV over the input voltage range of ±15V.
DS26LS32 and DS26LS32A Meet All
Requirements of RS-422 and RS-423
The DS26LS32A differs 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.

•
6k Minimum Input Impedance
100 mV Input Hysteresis on the DS26LS32 and
DS26LS32A, 200 mV on the DS26LS33

Operation From a Single 5V Supply
Each version provides an enable and disable function
common 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 commercial
operating temperature ranges.
