Overview
The MC3487DR, produced by Texas Instruments, is a quadruple differential line driver designed to meet the specifications of ANSI TIA/EIA-422-B and ITU Recommendation V.11. This device offers four independent differential line drivers, each with TTL-compatible inputs that are buffered to reduce current and minimize loading. The MC3487DR is optimized for use with the MC3486 quadruple line receiver and operates from a single 5V supply. It is available in a 16-pin SOIC package and is suitable for a variety of applications requiring reliable and fast differential signaling.
