LTC488IN#PBF

Drivers, Receivers, Transceivers Overview

The LTC488IN#PBF is a low-power 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 receivers with three-state outputs, an extended common-mode range from -7V to +12V, and a typical propagation delay of 28ns. It includes fail-safe circuitry to guarantee a high output state when inputs are open. The component is housed in a 16-lead plastic DIP package and supports industrial temperature ranges.

Drivers, Receivers, Transceivers Feature Summary

• Low power CMOS design for multipoint data transmission
• Extended common-mode range supporting ground differences up to ±7V
• Fail-safe feature guarantees high output state with open inputs
• Three-state outputs maintain high impedance during power-off

Drivers, Receivers, Transceivers Applications

• RS-485 or RS-422 multipoint bus communication systems
• Level translation between different logic families
• Industrial control networks requiring extended common-mode tolerance

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Ensure compatibility with existing board layouts regarding pin assignments and mechanical dimensions. Confirm lead-free finish specifications if required by assembly standards.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring multiple differential receivers without integrated drivers. Consider the 16-lead DIP package for through-hole mounting requirements. Evaluate the 7mA supply current against system power budgets compared to older bipolar alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC488/LTC489 family of low-power RS-485/RS-422 receivers. It serves as a complementary component to transceivers like the LTC486, enabling full-duplex or half-duplex configurations in distributed control systems.
