TRIPLE DIFFERENTIAL TRANSCEIVERS
SLLS459B – NOVEMBER 2000 – REVISED FEBRUARY 2002
description (continued)
The driver’s active-high enable and the receiver’s active-low enable are tied together internally and provide a
direction input for each driver/receiver pair.
The SN75LBC170 is characterized for operation over the temperature range of 0°C to 70°C. The SN65LBC170
is characterized for operation over the temperature range of –40°C to 85°C.
