POST OFFICE BOX 655303

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.
