LTC2864HS-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2864HS-1#TRPBF is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply voltage and supports data rates up to 20Mbps. The device features ±60V fault protection on transmission lines, ±15kV ESD protection on interface pins, and an extended common mode range of ±25V. It utilizes a 14-lead (150mil) plastic SO package and functions within an operating temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on data lines during all operational modes
• Features ±15kV HBM ESD protection on interface pins for reliable operation in harsh environments
• Supports extended ±25V common mode input range with guaranteed failsafe receiver operation

• Building automation, security systems, and HVAC

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the HS grade corresponds to the required industrial temperature range of -40°C to +125°C for your application environment. Ensure compatibility with the 14-lead SO package footprint during PCB layout verification.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring full-duplex communication at speeds up to 20Mbps. It is suitable for environments with significant ground loop voltages or electrical noise due to its robust fault protection and extended common mode range. Verify that the system logic levels are compatible with the 3V to 5.5V supply requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of low-power, fault-protected transceivers. It shares pinout compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades in existing designs. The 'H' designation specifies the high-temperature industrial grade, while the '-1' suffix denotes the full-duplex variant with driver enable functionality.

Drivers, Receivers, Transceivers FAQ

Does the LTC2864HS-1 support slew-rate limited transmission?

No, the LTC2864-1 variant supports only high-speed transmission up to 20Mbps. Slew-rate limited (low EMI) 250kbps operation is available in the LTC2864-2 variant.

What is the maximum short-circuit current for the driver outputs?

The driver outputs feature a progressive foldback current limit, with a maximum short-circuit current of ±250mA under fault conditions within the ±60V range.

How does the device handle open or shorted inputs?

The receiver includes a failsafe feature that guarantees a logic 1 output state if the differential input voltage is less than 50mV for more than approximately 3µs, covering open, shorted, or undriven line conditions.
