LTC1518IS#PBF

Drivers, Receivers, Transceivers Overview

The LTC1518IS#PBF is a high-speed, precision delay RS-485 quad line receiver manufactured by Analog Devices Inc. It operates from a single 5V supply and supports data rates up to 65 Mbps in the industrial temperature range (-40°C to +85°C). The device features a guaranteed propagation delay of 18.5ns ±3.5ns over the commercial range (0°C to 70°C) with typical skew of 500ps. It provides a wide input common mode range of -7V to 12V, ensuring compatibility with standard RS-485 buses. Key electrical parameters include a maximum supply current of 12mA, 4kV ESD protection, and short-circuit protection limiting output current to 50mA. The component is housed in a 16-lead SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Precision timing architecture ensures stable propagation delay and low skew across varying temperatures and common mode voltages.
• Hot Swap capability allows connection to live buses without loading data lines due to high input resistance when unpowered.
• Integrated fail-safe mechanisms guarantee a high logic state output during input shorts or open circuits.

Drivers, Receivers, Transceivers Applications

• High-speed RS-485/RS-422 differential bus receivers
• STS-1/OC-1 optical carrier data reception
• PECL line receiving interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free RoHS compliance as per manufacturer standards. Confirm the 'I' grade designation matches the required -40°C to +85°C operating temperature range for your application environment. Ensure the 16-lead SOIC footprint aligns with your PCB layout constraints before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when precise timing synchronization is critical for multi-drop networks. The LTC1518 offers superior skew performance compared to standard receivers. Consider the LTC1519 if independent enable control for receiver pairs is required instead of a global enable signal. Verify that the 5V supply voltage matches your system power rails.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1518/LTC1519 family of precision delay receivers. It is pin-compatible with the older LTC488 and LTC489 models, facilitating direct upgrades for improved speed and timing accuracy. The series is designed specifically for applications requiring tight tolerance on signal arrival times across multiple channels.

Drivers, Receivers, Transceivers Replacement Considerations

LTC488IS: Pin-compatible legacy alternative with lower 10Mbps speed rating. LTC1519IS: Functionally similar but features separate enable pins for receiver pairs rather than a single global enable.
