The MAX1489E is a quad, low-power line receiver designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 communications. Each receiver input is protected against ±15kV electrostatic discharge (ESD) shocks. These inputs have a ±25V range and feature hysteresis and time-domain filtering. The outputs are TTL and CMOS compatible. The MAX1489E has a 120kbps guaranteed data rate. Supply current is typically 350µA.
