5962-9318301Q2A

Overview

The Texas Instruments 5962-9318301Q2A is a half-duplex RS-485 differential bus transceiver housed in a 20-pin ceramic leaded chip carrier (CLCC) package. It integrates one transmitter and one receiver for serial communication. The device supports an input voltage range of -7V to +12V and operates within a temperature range of -55°C to +125°C. Key electrical specifications include a receiver hysteresis of 50 mV and a maximum supply current of 12 mA.

Feature Summary

• Supports RS-485 standard differential bus communication protocols
• Provides half-duplex data transmission capability with integrated driver and receiver
• Features high noise immunity through differential signaling architecture

Applications

• Industrial control systems requiring robust serial communication
• Building automation networks utilizing RS-485 buses
• Multi-drop communication environments with multiple transceivers

Procurement Notes

Verify the specific revision status and manufacturing date code against official Texas Instruments documentation before procurement. Ensure that the 20-CLCC package dimensions match the target PCB footprint requirements. Confirm that the military-grade qualification aligns with the project's environmental and reliability standards.

Selection Notes

Select this component when a ruggedized, ceramic-packaged RS-485 transceiver is required for harsh environments. Consider the half-duplex operation mode and the specific pinout of the 20-lead CLCC package during circuit design. Evaluate the thermal performance and power consumption characteristics relative to system constraints.

Part Context

This part belongs to the SN55LBC176 family of differential bus transceivers designed for reliable data transmission over long distances. It is characterized by its high common-mode rejection and protection against bus faults. The ceramic packaging ensures stability under extreme temperature variations compared to plastic alternatives.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing bus drivers and receivers regarding signal integrity and timing parameters if considering alternative components.
