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. The IL34C87T accepts TTL or CMOS input levels and translates these to RS-422 output levels. This part uses special output circuitry that enables the individual drivers to power down without loading down the bus. This device has separate enable circuitry for each pair of the four drivers. All inputs are protected against damage due to electrostatic discharge by diodes to VDD and ground.
