LTC2845CG#PBF

Drivers, Receivers, Transceivers Overview

The LTC2845CG#PBF 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. Operating from a single 3.3V supply with an external companion chip, it provides complete DTE or DCE port functionality. The device operates within a commercial temperature range of 0°C to 70°C and is housed in a 36-lead SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable protocol support for multiple serial interface standards
• Integrated cable termination eliminating discrete resistor networks
• Fail-safe receiver operation ensuring logic high output on floating inputs

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific CG suffix indicates the commercial temperature grade (0°C to 70°C). Confirm the 36-lead SSOP package matches the design footprint. Ensure the system architecture includes the required companion charge pump IC for voltage generation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 3.3V logic interface is required. Pair with the LTC2846 for integrated power generation or the LTC2847 if a separate 5V supply is available. Verify that the 36-lead SSOP package fits the board space constraints compared to the QFN alternative.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2845 series of multiprotocol transceivers. It functions as the signal conditioning core for serial interfaces, working in conjunction with power management chips like the LTC2846 or LTC2847 to form a complete port solution.
