LTC489CSW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC489CSW#TRPBF is a quad RS-485 line receiver manufactured by Analog Devices Inc. It operates on a single 5V supply with a typical supply current of 7mA. The device features four differential receivers with three-state outputs and supports data rates up to 10Mb/s. It provides an extended common mode range from -7V to +12V, allowing for ±7V ground differences between devices. Key electrical parameters include a typical propagation delay of 28ns, 60mV input hysteresis, and fail-safe functionality that guarantees a high output state when inputs are open. The component is housed in a 16-lead plastic wide SOIC (SW) package.

Drivers, Receivers, Transceivers Feature Summary

• Quad differential bus/line receivers designed for multipoint data transmission standard RS-485 applications
• Three-state outputs maintain high impedance over the entire common mode range
• Fail-safe feature guarantees a high output state when inputs are left open
• CMOS design offers significant power savings compared to bipolar counterparts

Drivers, Receivers, Transceivers Applications

• Low power RS-485/RS-422 receivers
• Level translator circuits
• Multipoint data transmission systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging rather than tube packaging. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C as specified in the manufacturer's documentation. Ensure compatibility with the 16-lead plastic wide SOIC footprint during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low power consumption and extended common mode voltage ranges. It serves as a pin-compatible replacement for the SN75175. Verify that the required operating temperature falls within the commercial range. Consider the 10Mb/s maximum data rate capability when designing high-speed communication interfaces.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC488/LTC489 family of low power differential bus receivers. The LTC489 variant specifically provides four independent receivers, whereas the LTC488 provides two. Both share similar electrical characteristics and package options, differing primarily in channel count and enable pin configurations.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet identifies the SN75175 as a pin-compatible alternative. Other related parts in the product line include the LTC488 for dual-receiver applications and various LTC14xx series transceivers for different power or speed requirements.
