LTC1483CN8#PBF

Drivers, Receivers, Transceivers Overview

The LTC1483CN8#PBF is an ultra-low power RS-485/RS-422 differential line transceiver in an 8-pin PDIP package. It operates on a single 5V supply (4.75V to 5.25V) with a maximum data rate of 250kb/s. The device features controlled slew rates to reduce EMI and includes thermal shutdown protection. Quiescent current is typically 80µA when disabled and 500µA when enabled without load, dropping to 1µA in shutdown mode. It supports a common-mode range from –7V to 12V and provides ±10kV ESD protection on driver and receiver inputs.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power CMOS design with shutdown mode reducing supply current to 1µA
• Controlled slew rate driver output stage minimizes electromagnetic interference
• Extended common-mode voltage range from –7V to 12V for robust bus operation
• Thermal shutdown circuit prevents damage during excessive power dissipation or faults

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485 and RS-422 communication systems
• Industrial networks requiring low electromagnetic emissions
• Level translation between different logic families
• Multi-drop bus applications supporting up to 32 transceivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix CN8 corresponds to the commercial temperature grade and 8-lead PDIP package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets the required environmental specifications for the intended operational environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs prioritizing minimal power consumption in RS-485 environments. The controlled slew rate makes it suitable for applications sensitive to signal reflections and high-frequency noise. Verify that the 250kb/s maximum data rate aligns with system timing requirements and that the 5V supply voltage matches the target platform.

Drivers, Receivers, Transceivers Part Context
