LTC2846CG#PBF

Drivers, Receivers, Transceivers Overview

The LTC2846CG#PBF is a 3-driver/3-receiver multiprotocol transceiver with on-chip cable termination. It operates from a single 3.3V supply (VIN: 3V to 3.6V) and includes a 1.2MHz boost switching regulator that generates a 5V VCC output. This powers an internal charge pump producing VDD and VEE supplies for RS-232 signaling. The device supports software-selectable protocols including RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 via M0, M1, and M2 pins. It is housed in a 36-lead SSOP package and functions within a commercial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable multiprotocol support for RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21
• Integrated 1.2MHz boost switching regulator for efficient 3.3V to 5V conversion
• On-chip automatic cable termination eliminating discrete resistor networks
• Complete DTE or DCE interface port when combined with companion chips like the LTC2844

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 suffix 'CG' indicates the commercial temperature grade (0°C to 70°C). Confirm the package type matches the 36-lead SSOP requirement. Ensure the ordering part number aligns with the manufacturer's current production status. Cross-reference the datasheet revision date to ensure compatibility with design specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single IC must handle multiple serial standards without external termination resistors. It requires a 3.3V logic supply and provides its own higher voltage rails. Consider pairing with the LTC2844 or LTC2845 for full control signal handling. Verify that the 36-lead SSOP footprint fits the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2846 series of multiprotocol transceivers. It is designed to work in conjunction with the LTC2844 or LTC2845 to form complete data terminal equipment ports. The CG suffix denotes the commercial operating temperature range, distinguishing it from the industrial grade IG variant which supports -40°C to 85°C.
