An overview of the

MAX1489E four, low - power line receiver is designed for the EIA/tia - 232, the EIA/tia - 562 and CCITT v. 28 communication in harsh environments. Each receiver input to prevent electrostatic discharge (ESD) of plus or minus 15 kv. These input + 25 V range and function of lag and time domain filtering. The output is TTL and CMOS compatible. MAX1489E 120 KBPS data rate. Power supply current is usually 350 (including.

MC1489 MAX1489E pin compatible, MC14C89 SN75189, SN75C189 DS1489, DS14C89. It can be in 14 - pin plastic bottom, so the package.

The key features

Enhancement of the ESD protection:

Plus or minus 15 kv, the human body model

Plus or minus 8 kv - IEC 1000-4-2, contact discharge

Plus or minus 15 kv, IEC 1000-4-2, air gap discharge

Blockade in ESD events free of charge

350 (including low power supply current

Input lag and time domain filtering to eliminate the necessity of external filtering

The stability of the input threshold

Pin compatible with MC1489, MC14C89 SN75189, SN75C189 DS1489, DS14C89

The application

Conform to the IEC in early 801 (IEC 801-2) or + / - 15 kv ESD protection standard equipment
