LTC2844IG#PBF

Drivers, Receivers, Transceivers Overview

The LTC2844IG#PBF is a 4-driver/4-receiver multiprotocol transceiver operating from a single 3.3V supply, designed to pair with the LTC2846 for complete DTE or DCE ports. It supports RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 protocols via software-selectable mode pins M0, M1, and M2. The device operates within an industrial temperature range of -40°C to +85°C and is housed in a 28-lead SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable multiprotocol support for RS232, RS449, EIA530, EIA530-A, V.35, V.36, and X.21 interfaces
• Integrated no-cable mode that forces driver outputs to high impedance and reduces supply current when cables are disconnected
• Fail-safe receiver operation ensuring logic high output if inputs are left floating or shorted
• TUV Rheinland certified NET1, NET2, and TBR2 compliance

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 #PBF indicates tube packaging rather than reel packaging. Confirm the IG designation corresponds to the -40°C to +85°C industrial temperature grade. Ensure the component matches the 28-lead SSOP physical footprint required by the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a software-configurable interface supporting multiple serial standards is required. It must be paired with the LTC2846 to generate necessary voltage levels and handle clock/data signals. Verify that the 3.3V single-supply architecture aligns with the system power budget.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2844/LTC2846 chipset family designed to form complete multiprotocol serial interface ports. The LTC2844 specifically handles control signals and data lines using external voltage supplies generated by the companion LTC2846 chip.
