•

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
