DS36954MX/E7001014

Overview

The DS36954MX/E7001014 is a quad differential bus transceiver manufactured by Texas Instruments, designed for high-speed parallel multipoint I/O bus applications. It features four drivers and four receivers in a half-duplex configuration, supporting RS422 and RS485 protocols. The device operates within a supply voltage range of 4.75V to 5.25V and includes a receiver hysteresis of 60 mV. It is housed in a compact 20-pin SOIC package with dimensions of 0.295 inches.

Feature Summary

• Integrates four differential drivers and four receivers for simultaneous data transmission and reception.
• Supports standard RS422 and RS485 communication protocols for reliable industrial connectivity.
• Features a 60 mV receiver hysteresis to enhance noise immunity on the bus lines.

Applications

• High-speed parallel multipoint I/O bus systems
• Industrial automation control networks
• Data acquisition systems requiring differential signaling

Procurement Notes
