LTC1518CS#PBF

Drivers, Receivers, Transceivers Overview

The LTC1518CS#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 0°C to 70°C temperature range. Typical skew for both tPLH/tPHL and channel-to-channel transitions is 500ps. It provides an input common mode range of –7V to 12V and includes fail-safe operation that guarantees a high output state when inputs are shorted or floating. The unit draws 12mA of supply current and 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 drive 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
• Fast-20/Fast-40 SCSI receivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the component matches the specific Analog Devices part number LTC1518CS#PBF. Confirm the suffix indicates the commercial temperature grade (0°C to 70°C) and the SOIC-16 package type. Ensure documentation aligns with the official datasheet specifications for electrical characteristics and pinout configuration.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring precise timing synchronization in differential bus systems. The tight propagation delay window minimizes duty cycle distortion in clocked data systems. Consider the 52Mbps maximum data rate and the –7V to 12V common mode range for compatibility with standard industrial interfaces.

Drivers, Receivers, Transceivers Part Context

The LTC1518 is part of the LTC1518/LTC1519 family of high-speed quad line receivers. It is pin-compatible with the older LTC488 and LTC489 models, facilitating direct upgrades for improved speed and timing precision while maintaining existing board layouts.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC1519 offers identical performance but features independent enable pins for receivers 1/2 and 3/4 instead of a single global enable. Other related parts include the LTC1520 and LTC1685 series for different interface requirements.
