DS26LS32AC/DS26LS32C/DS26LS32M/DS26LS33M
Quad Differential Line Receivers
General Description
Features
n High differential or common-mode input voltage ranges
of 7V on the DS26LS32 and DS26LS32A and 15V
on the DS26LS33
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.
n
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 have an input sensitivity of 500 mV over the input
voltage range of 15V.
n DS26LS32 and DS26LS32A meet all requirements of
RS-422 and RS-423
n 6k minimum input impedance
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.
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
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.

Note 3: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device
should be operated at these limits. The table of “Electrical Characteristics” provides conditions for actual device operation.
Note 4: All currents into device pins are shown as positive, all currents out of device pins are shown as negative, all voltages are referenced to ground, unless
otherwise specified. All values shown as max or min are so classified on absolute value basis.
Note 5: All typical values are V
