Overview
The SN65LVDS109DBTRG4 is a dual 4-port Low-Voltage Differential Signaling (LVDS) repeater produced by Texas Instruments. This component is part of the SN65LVDS109 family and is designed to meet or exceed the requirements of the ANSI EIA/TIA-644 standard. It features two identical banks, each with one differential line receiver connected to four differential line drivers. The device is packaged in a Thin Shrink Small-Outline Package (TSSOP) with 38 pins and operates over a temperature range of –40°C to 85°C.
