LTC2856IMS8-1#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2856IMS8-1#TRPBF is a low-power, half-duplex RS485/RS422 transceiver operating on a 5V supply. It supports a maximum data rate of 20Mbps and features a one-eighth unit load receiver input resistance exceeding 96kΩ, enabling up to 256 nodes per bus. The device includes enhanced ESD protection rated at ±15kV (HBM) and offers current-limited drivers with thermal shutdown for fault protection. It operates within a commercial temperature range of 0°C to 70°C and draws a maximum of 900µA in receive mode.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced electrostatic discharge protection withstands ±15kV human body model without latchup or damage.
• High input impedance receiver supports up to 256 nodes on the bus line.
• Integrated failsafe mechanism guarantees a high output state during floating or shorted input conditions.
• Driver outputs maintain high impedance when disabled or unpowered to prevent excessive power dissipation.

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 transceivers
• Level translator circuits
• Backplane transceiver systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube. Confirm the IMS8 designation matches the required 8-lead MSOP package type. Ensure the I-grade specification aligns with the intended operational environment requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring half-duplex communication with a 20Mbps data rate capability. The one-eighth unit load feature allows for extensive node counts compared to standard receivers. Consider the commercial temperature range limits when designing for environments outside 0°C to 70°C.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2856 series, which includes variants like the LTC2856-2 offering a lower 250kbps slew-rate limited option for reduced EMI. The -1 suffix specifically denotes the 20Mbps maximum data rate variant within the half-duplex family.
