2 High Differential or Common-Mode Input
Voltage Ranges of ±7V on the DS26LS32.
• ±0.2V Sensitivity Over the Input Voltage Range
on the DS26LS32.
• DS26LS32 Meet All Requirements of RS-422
and RS-423
• 6k Minimum Input Impedance
• 100 mV Input Hysteresis on the DS26LS32
• Operation From a single 5V Supply
• TRI-STATE Outputs, with Choice of
Complementary Output Enables for Receiving
Directly onto a Data Bus
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. The DS26LS33 has an input sensitivity of
500 mV over the input voltage range of ±15V.
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.
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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
