FEATURES

DESCRIPTION

The DS26LS32 and DS26LS32A are quad differential

• 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.
