General Description
   The IL34C87T is a quad differential line driver designed for digital data transmission over balanced lines. The IL34C87T meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. This enables the construction of serial and terminal interfaces while maintaining minimal power consumption.
