LTC487IN#PBF

Drivers, Receivers, Transceivers Overview

The LTC487IN#PBF is a quad low power RS-485 driver manufactured by Analog Devices Inc. It operates on a single 5V supply with a voltage range of 4.75V to 5.25V and features an extended common mode range from -7V to +12V. The device provides four differential drivers with three-state outputs, supporting data rates up to 10Mb/s. Typical supply current is 110µA, and propagation delay is 28ns typical. It includes thermal shutdown protection and glitch-free outputs for live insertion. The component is housed in a 16-lead plastic DIP package and supports commercial (0°C to 70°C) and industrial (-40°C to +85°C) temperature ranges.

Drivers, Receivers, Transceivers Feature Summary

• Quad differential bus/line driver designed for multipoint data transmission standard RS485 applications
• Extended common mode range permits ±7V ground difference between devices on the bus
• Thermal shutdown circuit prevents excessive power dissipation during bus contention or faults
• Power-up/down glitch-free driver outputs permit live insertion and removal of packages

Drivers, Receivers, Transceivers Applications

• Low power RS485/RS422 drivers
• Level translator
• Multipoint data transmission systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and operating temperature range. The IN suffix indicates a 16-lead plastic DIP package suitable for industrial temperatures ranging from -40°C to +85°C. Confirm lead-free finish status and RoHS compliance requirements against project specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad driver configuration is required without integrated receivers. Ensure the application utilizes a twisted pair cable terminated at both ends with characteristic impedance resistors. Verify that the system design accommodates the -7V to +12V common mode range and requires thermal protection against short circuits or bus contention scenarios.

Drivers, Receivers, Transceivers Part Context

The LTC487 belongs to the Analog Devices RS-485 interface family, specifically categorized as a low-power driver. It serves as a functional alternative to pin-compatible parts such as the SN75174 and DS96174. The device complements receiver components like the LTC489 to form complete half-duplex communication links for industrial and commercial data networks.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include SN75174, DS96174, µA96174, and DS96F174 due to pin compatibility.
