• Manufacturer Part Number: MC14C89
• Description: QUAD LOW POWER LINE RECEIVERS
• Manufacturer: ONSEMI [ON Semiconductor]

with EIA–232–E (formerly RS–232), the newer EIA–562
(which is a higher speed version of the EIA–232), and CCITT
V.28 Recommendations. EIA–562 was written around
modern integrated circuit technology, whereas EIA–232
retains many of the specifications written around the
