LTC1546IG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1546IG#TRPBF is a multiprotocol transceiver with on-chip cable termination, operating from a single 5V supply. It features three drivers and three receivers supporting RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols via software-selectable mode pins (M0, M1, M2). The device includes an internal charge pump generating approximately +8V and -7.5V using five external capacitors. It operates within a temperature range of -40°C to +85°C and is housed in a 28-lead SSOP package.

• Data routers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'I' grade designation matches the required industrial temperature range of -40°C to +85°C for your application environment. Ensure the ordering information aligns with the manufacturer's current documentation to avoid discrepancies.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a complete DTE or DCE port is required alongside the LTC1544 controller. It replaces both LTC1543 and LTC1344A functions without PCB changes. Verify that the interface protocol matches one of the supported standards and that the DB-25 connector gender aligns with the DTE/DTE configuration requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1546 series of multiprotocol serial interface chips. It is designed to work in conjunction with the LTC1544 to form a complete software-selectable interface port. The device pinout is compatible with the older LTC1543, facilitating direct upgrades in existing designs.
