Overview
The SN65LVDT2DBVT, produced by Texas Instruments, is a high-speed differential line receiver that complies with the ANSI TIA/EIA-644 standard. This device is part of the SN65LVDS family, which includes single-channel, low-voltage differential signaling (LVDS) line drivers and receivers. The SN65LVDT2 is specifically designed as a receiver and incorporates an integrated termination resistor, making it suitable for point-to-point and multidrop bus systems. It operates from a supply voltage range of 2.4V to 3.6V and is characterized for operation from –40°C to 85°C, making it ideal for various applications including battery-powered devices due to its low power consumption and high ESD tolerance.
