LTC1481CN8#PBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC1481CN8#PBF is an ultralow power RS-485 transceiver housed in an 8-pin PDIP package. It operates on a single 5V supply (4.75V to 5.25V) with a maximum data rate of 2.5 Mbits/s. The device features one driver and one receiver, supporting half-duplex communication. Quiescent current is typically 80mA when operating and drops below 1mA in shutdown mode. It provides ±10kV ESD protection, thermal shutdown circuitry, and a fail-safe receiver output. The component supports up to 32 transceivers on the bus and maintains high impedance outputs during power-off conditions.

Drivers, Receivers, Transceivers Feature Summary

• Ultralow power CMOS design significantly reduces consumption compared to bipolar counterparts
• Integrated thermal shutdown prevents excessive power dissipation during bus contention or faults
• Fail-safe receiver guarantees a high output state when differential inputs are left open
• Glitch-free driver outputs permit live insertion or removal without system disruption

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485/RS422 applications
• Low power RS-485/RS422 transceiver networks
• Level translator circuits

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CN8#PBF against the manufacturer's official documentation to confirm the PDIP-8 package type and commercial temperature range specifications. Ensure that the ordering information matches the exact part number required for your bill of materials, as variations in suffixes may indicate different packaging formats or extended industrial temperature ratings.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring low quiescent current and robust ESD protection in RS-485 environments. The device is suitable for systems needing a single 5V supply and half-duplex communication capabilities. Consider the thermal shutdown feature for fault-tolerant applications and verify that the 2.5 Mbits/s data rate meets the network speed requirements.
