POST OFFICE BOX 655303 • DALLAS, TEXAS 75265
description (continued)
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 are characterized for operation from –40°C to 85°C.
The SN75LVDS387, SN75LVDS389, and SN75LVDS391 are characterized for operation from 0°C to 70°C.
