Overview
The SN75LVDS389DBTRG4 is a high-speed differential line driver produced by Texas Instruments. This component is part of the SNx5LVDS3xx family, which includes devices with 4, 8, or 16 differential line drivers. The SN75LVDS389 specifically features eight differential line drivers, making it suitable for applications requiring high-speed data transmission over long distances.
This device operates within a temperature range of 0°C to 70°C and is packaged in a Thin Shrink Small-Outline Package (TSSOP) with a 16-pin configuration. It is designed to support Low-Voltage TTL (LVTTL) logic inputs and provides bus-pin ESD protection up to 4 kV.
