LTC2856CDD-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2856CDD-2#TRPBF is a low-power, half-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a single 5V supply and supports a maximum data rate of 250kbps for low EMI applications. The device features enhanced ESD protection capable of withstanding ±15kV (human body model) without latchup or damage. It incorporates current-limited drivers and thermal shutdown to prevent excessive power dissipation during bus contention or faults. The receiver provides a failsafe feature ensuring a high output state under floating or shorted input conditions. It utilizes an 8-lead 3mm × 3mm DFN package.

Drivers, Receivers, Transceivers Feature Summary

• Slew rate limited driver outputs control high frequency EMI emissions
• High input impedance supporting up to 256 nodes per bus
• Guaranteed failsafe receiver operation over the entire common mode range
• Power up/down glitch-free driver outputs

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the C-grade designation corresponds to the commercial temperature range of 0°C to 70°C for your application requirements. Ensure compatibility with the 8-lead DFN package dimensions during PCB layout planning.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring reduced electromagnetic interference through slew rate limiting at data rates up to 250kbps. It is suitable for systems needing high node density due to its one-eighth unit load receiver characteristic. Consider the half-duplex configuration if full-duplex communication is not required. Verify that the commercial temperature range meets the environmental constraints of the deployment site.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2856 series of low power RS485/RS422 transceivers. It is distinct from the LTC2857 and LTC2858 series which offer full-duplex capabilities. The -2 suffix denotes the 250kbps slew-rate limited variant, while the -1 variant supports 20Mbps. The CDD-2#TRPBF specifically identifies the commercial grade, 8-lead DFN package, half-duplex function, and tape and reel packaging format.
