The SN65LVDS049 is a dual flow-through differential line driver-receiver pair that uses low-voltage differential signaling (LVDS) to achieve signaling rates as high as 400 Mbps. The TIA/EIA-644-A standard compliant electrical interface provides a minimum differential output voltage magnitude of 250 mV into a 100- load and receipt of signals with up to 1 V of ground potential difference between a transmitter and receiver. The LVDS receivers have internal failsafe biasing that places the outputs into a known high state for unconnected differential inputs.

The intended application of this device and signaling technique is for point-to-point baseband data transmission over controlled impedance media of approximately 100- characteristic impedance.
