Overview
The SN65LVDS2DBVR, produced by Texas Instruments, is a high-speed differential line driver and receiver designed to meet or exceed the ANSI TIA/EIA-644 standard. This component is part of the SN65LVDS series, which includes single, low-voltage, differential line drivers and receivers. The SN65LVDS2 is available in small-outline transistor packages such as SOT-23 and SOIC, making it suitable for a variety of applications where high-speed data transmission is required.
The device is characterized for operation from –40°C to 85°C, making it versatile for different environmental conditions. It is particularly ideal for battery-powered applications due to its low power consumption, low electromagnetic interference (EMI), and high electrostatic discharge (ESD) tolerance.
