LTC1520CS#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1520CS#TRPBF is a high-speed precision quad line receiver manufactured by Analog Devices Inc. It operates from a single 5V supply and supports data rates up to 50Mbps. The device features a propagation delay of 18ns with a tolerance of ±3ns over the operating temperature range. Key electrical parameters include a typical tPLH/tPHL skew of 500ps and channel-to-channel skew of 400ps. The input resistance is ≥18kΩ, even when unpowered, enabling hot swap capability. The part draws 12mA of supply current and is housed in a 16-lead narrow SO package.

Drivers, Receivers, Transceivers Feature Summary

• Precision timing architecture ensures stable propagation delays and low skew across wide input common mode ranges and temperatures.
• Hot swap capable design maintains high input resistance (≥18kΩ) when unpowered or disabled to prevent loading data lines.
• Integrated protection includes thermal shutdown and short-circuit current limiting to prevent latchup damage during fault conditions.

Drivers, Receivers, Transceivers Applications

• High speed backplane interface
• PECL and LVDS line receivers
• Level translator
• Tapped delay line

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging configuration. Confirm the CS subcode corresponds to the commercial temperature range of 0°C to 70°C. Ensure the manufacturer is identified as Analog Devices Inc., which acquired Linear Technology. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring precise differential signal reception at speeds up to 50Mbps. The tight propagation delay matching makes it suitable for parallel data transmission where timing skew must be minimized. Verify that the system operates on a single 5V supply and requires rail-to-rail input common mode handling. Consider the 16-lead narrow SO package constraints for PCB layout.

Drivers, Receivers, Transceivers Part Context

The LTC1520 series consists of high-speed precision quad line receivers designed for demanding communication interfaces. The CS variant denotes the commercial grade version available in a plastic small outline package. This model is part of the broader portfolio of interface products from Analog Devices, formerly Linear Technology, focusing on reliable signal integrity solutions.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers include the LTC1518 and LTC1519, which are also high-speed quad RS485 receivers. These alternatives share similar performance characteristics but may differ in common mode voltage ranges. Verify pinout compatibility and electrical specifications before substitution.
