LTC2844CG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2844CG#TRPBF is a 3.3V software-selectable multiprotocol transceiver housed in a 28-lead SSOP package, designed for commercial grade operation between 0°C and 70°C. It integrates four drivers and four receivers to support RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols. The device operates from a single 3.3V supply, utilizing the LTC2846 for voltage generation. Electrical characteristics include a typical VCC supply current of 2.7 mA (no load) and 120 mA (full load). Driver rise/fall times are typically 25 ns, with propagation delays ranging from 20 ns to 75 ns depending on the protocol mode.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable multiprotocol interface supporting multiple serial standards via M0, M1, and M2 pins
• Integrated fail-safe receiver operation ensuring logic high output when inputs are floating or shorted
• Dedicated no-cable mode that forces driver outputs to high impedance and reduces supply current below 600 µA
• TUV Rheinland certified compliant with NET1, NET2, and TBR2 safety requirements

Drivers, Receivers, Transceivers Applications

• Data networking equipment
• Channel Service Unit/Data Service Unit (CSU/DSU)
• Data routers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific CG suffix indicates the commercial temperature range (0°C to 70°C), distinct from the IG industrial variant (-40°C to 85°C). Confirm the TRPBF suffix denotes tape and reel packaging containing 2000 units. Ensure compatibility with the required 28-lead SSOP footprint during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing a complete DTE or DCE port requiring software-configurable protocol switching. It must be paired with the LTC2846 to generate the necessary internal charge pump voltages. Verify that the application requires the specific pinout and electrical characteristics defined for the 28-lead SSOP package.
