LTC488ISW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC488ISW#TRPBF is a low-power quad RS-485 line receiver manufactured by Analog Devices Inc. It operates on a single 5V supply with a specified range of 4.75V to 5.25V and draws a typical supply current of 7mA. The device features four 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 ±7V ground differences between devices. Key electrical parameters include a typical propagation delay of 28ns, 60mV input hysteresis, and ESD protection rated at 2kV (Human Body Model). The component is housed in a 16-lead plastic wide SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Quad differential bus/line receivers designed for multipoint data transmission standards including RS-485 and RS-422.
• Fail-safe feature guarantees a high output state when inputs are left open or floating.
• CMOS design ensures significant power savings while maintaining ruggedness against overload and ESD damage.
• Three-state outputs maintain high impedance across the entire common-mode range and during power-off conditions.

Drivers, Receivers, Transceivers Applications

• Low power RS-485 and RS-422 communication networks
• Level translation interfaces between different logic families
• Multipoint data transmission systems requiring extended common-mode range

Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the industrial temperature grade (-40°C to +85°C) matches the operational environment specifications. Ensure the 16-lead wide SOIC footprint aligns with the target PCB layout constraints before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a low-power solution is required for RS-485 applications without integrated driver functionality. The device is suitable for designs needing extended common-mode voltage tolerance to accommodate ground potential differences. Consider the 28ns propagation delay and 10Mb/s maximum data rate capabilities for high-speed bus implementations.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC488/LTC489 family of low-power differential receivers. The LTC488 variant offers independent enable controls for all four receivers, whereas the LTC489 groups them into two pairs. Both variants share identical electrical characteristics and pinouts, differing primarily in control logic configuration for system integration flexibility.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet indicates pin compatibility with the SN75173 for the LTC488 function. Designers should verify that any substitute component maintains the same 16-lead SOIC package dimensions and electrical specifications, particularly the 7mA supply current and 10Mb/s data rate limits.
