Overview
The SN65LVDS180DG4 is a high-speed differential line driver and receiver produced by Texas Instruments. It is part of the SN65LVDSxxx family, which operates using low-voltage differential signaling (LVDS) to achieve high signaling rates. This device is compliant with the TIA/EIA-644 standard and is designed to operate from a single 3.3-V supply, with a voltage range of 3.0 V to 3.6 V. The SN65LVDS180DG4 is suitable for applications requiring high-speed data transmission with low power consumption and high immunity to common-mode noise.
