DESCRIPTION
The SN55183 dual differential line driver is designed to provide differential output signals with high current
capability for driving balanced lines, such as twisted pair, at normal line impedances without high power
dissipation. The device can be used as a TTL expander/phase splitter, because the output stages are similar to
TTL totem-pole outputs.
The driver is of monolithic single-chip construction, and both halves of the dual circuits use common power
supply and ground terminals.
The SN55183 is characterized for operation over the full military temperature range of –55°C to 125°C.
