LTC1545CG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1545CG#TRPBF is a software-selectable multiprotocol transceiver housed in a 36-lead SSOP package. It operates from a single 5V supply and supports RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols via mode select pins M0, M1, and M2. The device integrates five drivers and five receivers, including V.11 differential, V.10/V.28 single-ended, and V.35 balanced interfaces. Electrical characteristics include a typical VCC supply current of 5mA (no load) and logic input high voltage of 2V. Operating temperature range for the C grade is 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable protocol support for multiple serial interface standards
• Integrated five-driver and five-receiver architecture
• Fail-safe receiver operation with logic high output on floating inputs
• No-cable mode functionality reducing supply current below 200mA

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 ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the CG suffix corresponds to the commercial temperature range of 0°C to 70°C as defined in the manufacturer's datasheet. Ensure compatibility with the required 36-lead SSOP footprint during procurement planning.

Drivers, Receivers, Transceivers Selection Notes
