_______________Ge n e ra l De s c rip t io n

____________________________Fe a t u re s

The MAX1489E q ua d , low-p owe r line re c e ive r is

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

communications in harsh environments. Each receiver

inp ut is p rote c te d a g a ins t ± 15kV e le c tros ta tic d is -

charge (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.

♦ 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, a nd

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

packages.

♦ Stable Input Thresholds

♦ Pin Compatible with MC1489, MC14C89, SN75189,

SN75C189, DS1489, and DS14C89
