FEATURES
DESCRIPTION
The DS26LS32 and DS26LS32A are quad differential
2
• High Differential or Common-Mode Input
line receivers designed to meet the RS-422, RS-423
Voltage Ranges of ±7V on the DS26LS32 and
and Federal Standards 1020 and 1030 for balanced
DS26LS32A and ±15V on the DS26LS33
and unbalanced digital data transmission.
• ±0.2V Sensitivity Over the Input Voltage Range
The DS26LS32 and DS26LS32A have an input
on the DS26LS32 and DS26LS32A, ±0.5V
sensitivity of 200 mV over the input voltage range of
Sensitivity on the DS26LS33
±7V and the DS26LS33 has an input sensitivity of
• DS26LS32 and DS26LS32A Meet All
500 mV over the input voltage range of ±15V.
Requirements of RS-422 and RS-423
The DS26LS32A differs in function from the popular
• 6k Minimum Input Impedance
DS26LS32 and DS26LS33 in that input pull-up and
• 100 mV Input Hysteresis on the DS26LS32 and
pull-down resistors are included which prevent output
DS26LS32A, 200 mV on the DS26LS33
oscillation on unused channels.
• Operation From a Single 5V Supply
Each version provides an enable and disable function
common to all four receivers and features TRI-STATE
• TRI-STATE Outputs, with Choice of
outputs with 8 mA sink capability. Constructed using
Complementary Output Enables for Receiving
low power Schottky processing, these devices are
Directly onto a Data Bus
available over the full military and commercial
operating temperature ranges.
