LTC1545IG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1545IG#TRPBF is a software-selectable multiprotocol transceiver housed in a 36-lead SSOP package. It integrates five drivers and five receivers to support RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols. Operating from a single 5V supply with the LTC1343 charge pump, it features mode selection via M0, M1, and M2 pins. Electrical characteristics include a typical VCC supply current of 5mA (no load) and logic input high voltage of 2V. The device operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable protocol support for multiple serial standards
• Integrated cable termination control compatible with LTC1344A
• Fail-safe receiver operation prevents false triggering on floating inputs
• No-cable mode reduces power consumption when disconnected

Drivers, Receivers, Transceivers Applications

• Data networking equipment ports
• Channel Service Unit/Data Service Unit (CSU/DSU)
• Data routers requiring multiprotocol compatibility

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube packaging. Confirm the 'I' grade designation matches the required industrial temperature range of -40°C to +85°C. Ensure the component source is Analog Devices Inc. or an authorized distributor to guarantee authenticity and compliance with RoHS standards.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing a DTE or DCE interface port that requires flexibility across various serial standards without hardware changes. It pairs with the LTC1343 for signal generation and the LTC1344A for termination. Consider the 36-lead SSOP footprint and ensure adequate decoupling capacitors are placed near the VCC, VDD, and VEE pins for stable operation.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1545 series of multiprotocol transceivers. It is designed to work in conjunction with the LTC1343 controller and LTC1344A termination chip to form a complete software-configurable serial interface solution. The IG suffix denotes the industrial temperature range variant.
