Overview
The SN65LVDT348PW is a high-speed, quadruple differential receiver produced by Texas Instruments. This component is designed to meet or exceed the requirements of the ANSI TIA/EIA-644A standard, making it suitable for a wide range of high-speed data transmission applications. It features a wide common-mode input voltage range of -4 V to 5 V, allowing it to receive signals with up to 3 V of ground noise or various differential and single-ended logic levels. The device is packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package) and operates over a temperature range of -40°C to 85°C.
