ST1480ABDR

Product Overview

The ST1480ABDR is an STMicroelectronics transceiver intended for half-duplex RS422 and RS485 serial communication. The device provides one driver and one receiver in an 8-SOIC surface-mount package. It operates from a 3V to 3.6V supply and supports a data rate of 15Mbps. The specified receiver hysteresis is 30 µV, and the operating temperature range is -40°C to 85°C. Its current lifecycle status is Active.

Key Features

• Half-duplex RS422 and RS485 transceiver with a 1/1 driver and receiver configuration.
• Supports a 15Mbps data rate for serial signaling.
• Operates from a 3V to 3.6V supply.
• Includes a 30 µV receiver hysteresis specification.
• Rated for -40°C to 85°C operating temperature.
• Supplied in an 8-SOIC surface-mount package.
• Current lifecycle status is Active.

Applications

• Serial communication links between controllers and peripheral equipment.
• Sensor data acquisition buses using RS422 or RS485 signaling.
• Embedded systems needing a 3V to 3.6V interface transceiver.
• Equipment interconnects requiring half-duplex serial operation.

Design & Procurement Notes

Designers should confirm that the board power rail is within 3V to 3.6V before selecting this transceiver. The 8-SOIC surface-mount package and 3.90mm width affect footprint and reflow layout. The 15Mbps data rate and half-duplex 1/1 topology define the available serial signaling arrangement, while the -40°C to 85°C operating range should be checked against the enclosure thermal environment. The 30 µV receiver hysteresis value may be considered during input threshold margin analysis. The supplied lifecycle status is Active, which should be considered during component selection, but final qualification and system-level validation remain dependent on the overall application.
