1ꢀ5k EꢁDꢂ-rotected, Quad,

Lowꢂ-ower Rꢁꢂ232 Line Receiver

_______________General Description

____________________________Features

The MAX1489E quad, low-power line receiver is

designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28

communications in harsh environments. Each receiver

input is protected against 15ꢀV electrostatic dis-

charge (ESD) shocꢀs. These inputs have a 25V range

and feature hysteresis and time-domain filtering. The

outputs are TTL and CMOS compatible. The MAX1489E

has a 120ꢀbps guaranteed data rate. Supply current is

typically 350µA.

ꢀ Enhanced ESD Protection:

15kV—Human Body Model

8kV—IEC1000-4-2, Contact Discharge

15kV—IEC1000-4-2, Air-Gap Discharge

ꢀ Latchup Free During an ESD Event

ꢀ Low 350µA Supply Current

ꢀ Input Hysteresis and Time-Domain Filtering

Eliminate the Need for External Filtering

The MAX1489E is pin compatible with the MC1489,

MC14C89, SN75189, SN75C189, DS1489, and

DS14C89. It is available in 14-pin plastic DIP and SO

pacꢀages.

ꢀ Stable Input Thresholds

ꢀ Pin Compatible with MC1489, MC14C89, SN75189,

SN75C189, DS1489, and DS14C89
