Octal LVDS Driver

Description

This family of 4, 8, and 16 differential line drivers implements the electrical characteristics of low-voltage differential signaling (LVDS). This signaling technique lowers the output voltage levels of 5-V differential standard levels (such as EIA/TIA-422B) to reduce the power, increase the switching speeds, and allow operation with a 3.3-V supply rail. Any of the 16 current-mode drivers will deliver a minimum differential output voltage magnitude of 247 mV into a 100-Ω load when enabled.

When disabled, the driver outputs are high-impedance. Each driver input (A) and enable (EN) have an internal pulldown that will drive the input to a low level when open-circuited.

The SN65LVDS387, SN65LVDS389, and SN65LVDS391 devices are characterized for operation from –40°C to 85°C. The SN75LVDS387, SN75LVDS389, and SN75LVDS391 devices are characterized for operation from 0°C to 70°C.
