LTC489CSW#PBF

Drivers, Receivers, Transceivers Overview

The LTC489CSW#PBF is a quad RS-485 line receiver manufactured by Analog Devices Inc. It operates on a single 5V supply with a voltage range of 4.75V to 5.25V and draws a typical supply current of 7mA. The device features four differential receivers with three-state outputs, supporting data rates up to 10Mb/s. It provides an extended common mode range from -7V to +12V, allowing for significant ground differences between bus devices. Key electrical parameters include a typical propagation delay of 28ns, input hysteresis of 60mV, and ESD protection ratings.

Drivers, Receivers, Transceivers Feature Summary

• Quad differential receivers designed for multipoint data transmission in RS-485 and RS-422 applications
• Three-state outputs maintain high impedance across the entire common mode range and when powered off
• Fail-safe feature guarantees a high output state when receiver inputs are left open or floating
• CMOS architecture provides low power consumption while maintaining ruggedness against overload and ESD damage

Drivers, Receivers, Transceivers Applications

• Low power RS-485 and RS-422 receiver circuits
• Level translation interfaces
• Multipoint data transmission systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and RoHS compliance as per manufacturer standards. Confirm the SW package designation corresponds to the 16-lead plastic wide SOIC form factor. Ensure the 'C' grade matches the required commercial operating temperature range of 0°C to 70°C for the intended deployment environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad receiver configuration is required without integrated drivers. Compare against the LTC488 if only two enable pins are preferred instead of the LTC489's split EN12/EN34 control scheme. Consider the 10Mb/s speed capability and 7mA quiescent current against system power budgets and signal integrity requirements for twisted-pair cabling.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC488/LTC489 family of low-power differential bus receivers. It is pin-compatible with industry standard parts like the SN75175. The CSW variant specifically denotes the commercial temperature range and the wide SOIC surface-mount package, distinguishing it from DIP or industrial temperature graded versions within the same product line.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include the LTC488CSW#PBF for dual-receiver functionality.
