General 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.
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 oscillation
on unused channels.
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 commerical operating temperature ranges.
