LTC2862AMPS8-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2862AMPS8-2#PBF is a low-power RS485/RS422 transceiver manufactured by Analog Devices. It operates on a 3V to 5.5V supply and supports half-duplex communication at a maximum data rate of 250kbps. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It provides Level 4 IEC ESD protection and ±40kV HBM ESD protection on the A and B pins. The component includes an extended common mode range of ±25V and guaranteed failsafe receiver operation. It is housed in an 8-lead (150mm) Plastic SO package and is rated for an operating temperature range from -55°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V
• Level 4 IEC ESD and EFT protection on interface pins
• Extended common mode input range of ±25V
• Guaranteed failsafe receiver operation with noise filtering

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Automotive and transportation electronics
• Building automation, security systems, and HVAC
• Medical equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'MPS8' indicates the military-grade temperature range (-55°C to 125°C) and plastic SOIC package style. Confirm the '#PBF' designation ensures lead-free compliance and RoHS adherence. Cross-reference the datasheet revision to ensure compatibility with system requirements regarding shutdown current and driver output characteristics.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when high reliability across extreme temperatures is required. The '-2' suffix specifies the slew-rate limited 250kbps option, which reduces electromagnetic interference compared to the 20Mbps version. Ensure the application benefits from the integrated ±60V fault tolerance to minimize external protection components.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862A family of robust RS485/RS422 transceivers. It shares pinout compatibility with the standard LTC2862 and LT1785 devices. The MPS8 package distinguishes it from commercial (CS8), industrial (IS8), and high-temperature (HS8) variants by offering the widest operational temperature range.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible alternatives include the LTC2862ACS8-2#PBF, LTC2862AIS8-2#PBF, and LTC2862AHS8-2#PBF. These variants offer identical functionality but differ in their specified operating temperature ranges.
