LTC2845CG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2845CG#TRPBF is a 3.3V software-selectable multiprotocol transceiver featuring five drivers and five receivers. It supports RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols via mode select pins M0, M1, and M2. Operating from a single 3.3V supply with internal charge pump generation of VDD (approx. 8V) and VEE (approx. -7V), it forms a complete DTE or DCE port when paired with the LTC2846 or LTC2847. The component is housed in a 36-lead SSOP package and operates within a commercial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable protocol support for multiple serial standards including RS232, V.35, and X.21
• Integrated cable termination networks eliminating discrete resistor requirements
• Fail-safe receiver operation ensuring logic high output during floating or shorted input conditions
• No-cable mode functionality that reduces supply current and forces driver outputs to high impedance

Drivers, Receivers, Transceivers Applications

• Data networking equipment interfaces
• Channel Service Unit (CSU) and Data Service Unit (DSU) implementations
• Data router serial ports

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type and operating temperature range. Confirm that the component designation corresponds to the Analog Devices manufacturer. Ensure compliance with RoHS directives as indicated in official documentation before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring a compact multiprotocol interface solution. Pair with the LTC2846 for 3.3V systems or the LTC2847 for 5V systems with 3.3V logic. Consider the 36-lead SSOP package constraints regarding thermal dissipation and PCB layout space availability for the required decoupling capacitors.
