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
DS26LS33 and DS26LS33A have an input sensitivity of
500 mV over the input voltage range of
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
