Description

The HIN14C89E is a high-ESD tolerant, very low power, quad RS-232 receiver interface circuit that is designed to meet EIA/TIA-232, EIA/TIA-562, and CCITT V.28 specifications.

The HIN14C89E receivers can handle up to ±25V, and have a 3 to 7kW input impedance. The receivers have hysteresis and on-chip noise filtering to improve noise rejection and make external filtering components unnecessary. The outputs are TTL and CMOS compatible and operate at 240Kbps.
