ST1480ACDR

Product Overview

The ST1480ACDR from STMicroelectronics is a surface-mount transceiver for RS422 and RS485 serial communication. It provides one driver and one receiver in a half-duplex configuration, with a 3 V to 3.6 V supply range and an operating temperature range of 0°C to 70°C. The 8-SOIC package has a 0.154 in, 3.90 mm width, supporting board-level interface designs. The transceiver is suited to interface positions where a single differential communication channel is shared between transmit and receive directions.

Key Features

• Surface-mount 8-SOIC package, 0.154 in / 3.90 mm width

Applications

• RS422 or RS485 serial communication links
• Half-duplex data paths between controllers and interface devices
• 15 Mbps serial data exchange in 3 V to 3.6 V systems
• Board-level interface signaling within surface-mount electronic assemblies

Design & Procurement Notes

Design attention should focus on matching the ST1480ACDR to a 3 V to 3.6 V supply and a 0°C to 70°C operating environment. The half-duplex, 1/1 driver and receiver architecture is appropriate for RS422 or RS485 links where transmit and receive directions are managed on the same channel. The 15 Mbps data rate and 30 µV receiver hysteresis should be considered against the target link speed and receiver input conditions. For procurement and layout, verify the 8-SOIC surface-mount footprint, 0.154 in width, and 3.90 mm body dimension against the PCB library and mechanical clearance.
