LTC1519CS#PBF

Drivers, Receivers, Transceivers Overview

The LTC1519CS#PBF is a high-speed, precision delay quad line receiver manufactured by Analog Devices Inc. It operates from a single 5V supply and supports data rates up to 52Mbps. The device features a propagation delay of 18.5ns with a tolerance of -3.5ns over the commercial temperature range (0°C to 70°C). Typical skew for both tPLH/tPHL and channel-to-channel transitions is 500ps. It provides a wide input common mode range of –7V to 12V and includes fail-safe operation to guarantee a high output state when inputs are shorted or floating. The component is housed in a 16-lead plastic SO package.

Drivers, Receivers, Transceivers Feature Summary

• Precision timing architecture ensures stable propagation delays and low skew across wide input common mode and temperature ranges.
• Integrated fail-safe mechanism guarantees a logic high output state during input short-circuit or open conditions.
• Hot Swap capability allows connection without loading data lines due to high input resistance even when unpowered.
• Short-circuit protection limits output current to prevent latchup damage during fault conditions.

Drivers, Receivers, Transceivers Applications

• High speed RS485/RS422 receivers
• STS-1/OC-1 data receivers
• PECL line receivers
• Level translators

Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the CS suffix corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the 16-lead SO package matches the PCB footprint requirements. Check datasheet specifications for absolute maximum ratings to prevent device impairment during installation.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring precise timing synchronization in differential bus systems. The low skew characteristics minimize duty cycle distortion in clocked data systems. Consider the 52Mbps maximum data rate limit for signal integrity. Verify compatibility with existing driver outputs and termination requirements for twisted pair transmission lines.

Drivers, Receivers, Transceivers Part Context

The LTC1519 is part of the LTC1518/LTC1519 family of precision delay receivers. It is pin-compatible with the older LTC488 and LTC489 models, facilitating direct upgrades in legacy designs. The device shares architectural similarities with other high-speed line receivers but offers tighter propagation delay control over varying environmental conditions.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC1518CS#PBF serves as a functional substitute within the same family, differing primarily in enable pin configuration. Designers should verify pinout compatibility before substitution to ensure proper circuit operation without hardware modifications.
