LTC2862AIS8-1#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2862AIS8-1#PBF is a half-duplex RS-485/RS-422 transceiver housed in an 8-lead SOIC package. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps. The device features ±60V overvoltage fault protection on interface pins, ±40kV HBM ESD protection, and Level 4 IEC ESD/EFT compliance. It guarantees failsafe receiver operation with an extended common mode range of ±25V and high input impedance supporting up to 224 nodes.

Drivers, Receivers, Transceivers Feature Summary

• Robust fault tolerance with ±60V overvoltage protection on A/B pins during all operational modes
• High electromagnetic compatibility through ±40kV HBM ESD and Level 4 IEC ESD/EFT protection
• Enhanced signal integrity via fully balanced differential receiver thresholds for low duty cycle distortion
• Guaranteed failsafe logic state when inputs are open, shorted, or undriven across the full common mode range

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS-compliant packaging. Confirm the 'I' grade designation matches the required -40°C to +85°C operating temperature range for your application environment. Ensure the SOIC-8 footprint aligns with your PCB layout constraints before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring high-speed 20Mbps transmission with robust fault protection. The 'A' series offers improved ESD and noise immunity compared to standard versions. Choose the '-1' suffix variant specifically for high-speed data rates; the '-2' variant is limited to 250kbps with slew-rate limiting for lower EMI generation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862A family of low-power transceivers. It is pin-compatible with the legacy LTC2862 and LT1785 devices, facilitating direct upgrades. The 'I' suffix denotes industrial temperature performance, while the '#PBF' suffix confirms lead-free manufacturing compliant with environmental directives.

Drivers, Receivers, Transceivers FAQ

How does the LTC2862A handle ground loop voltages?

It features an extended common mode input range of ±25V, allowing reliable operation even when significant voltage differences exist between node grounds.

What is the failsafe mechanism in this transceiver?

The receiver guarantees a logic high output if the differential input voltage falls below -75mV, ensuring a known idle state when lines are open or undriven.

Is the device protected against short circuits?

Yes, the driver outputs include current limiting and thermal shutdown protection, capable of withstanding short circuits to any voltage within the ±60V absolute maximum rating.
