DS26LS32CMX

Overview

The DS26LS32CMX is a quad differential line receiver manufactured by Texas Instruments, designed for balanced and unbalanced digital data transmission. It operates from a single 5V supply and features TRI-STATE outputs with an 8 mA sink capability. The device meets RS-422 and RS-423 standards, offering high differential or common-mode input voltage ranges of ±7V. It includes 100 mV input hysteresis and a minimum input impedance of 6 kΩ. Typical propagation delay is 25 ns at VCC = 5V and TA = 25°C.

Feature Summary

• Quad differential line receivers designed to meet RS-422, RS-423, Federal Standards 1020 and 1030
• High differential or common-mode input voltage ranges of ±7V on the DS26LS32
• TRI-STATE outputs with 8 mA sink capability and choice of complementary output enables
• Input pull-up and pull-down resistors included to prevent output oscillation on unused channels

Applications

• Two-wire balanced interface (RS-422)
• Single wire with driver ground reference (RS-423)

Procurement Notes

Verify the specific suffix against the official datasheet to confirm package type and temperature range. Confirm RoHS compliance status as indicated in the packaging information addendum. Ensure the ordering part number matches the required commercial or military specifications before procurement.

Selection Notes

Select this component when a quad differential receiver compliant with RS-422/RS-423 is required. Verify that the ±7V common-mode range suits the application environment. Check if the commercial temperature range (0°C to +70°C) aligns with system requirements.

Part Context

This device belongs to the DS26LS32 family of quad differential line receivers. It is functionally similar to the DS26LS32AC but lacks the internal pull-up/pull-down resistors found in the 'A' variant. It is constructed using low power Schottky processing technology.

Replacement Considerations

DS26LS32ACM/NOPB: Includes internal pull-up and pull-down resistors to prevent output oscillation on unused channels.

FAQ
