Overview
The DS34LV86T is a high-speed quad differential CMOS receiver designed by Texas Instruments. This component is engineered to meet the requirements of both TIA/EIA-422-B and ITU-T V.11 standards. It features a low power CMOS design, making it ideal for battery-powered and power-conscious applications. The device operates at 3.3V and has a typical low static ICC of 9 mA, which minimizes power consumption. The Tri-State enables allow the device to be disabled when not in use, further reducing power consumption. The receiver can detect signals as low as ±200 mV over a common mode range of ±10V and is compatible with TTL and LVCMOS levels.
