DS89C386 Twelve Channel CMOS Differential Line Receiver
May 1995
DS89C386
Twelve Channel CMOS Differential Line Receiver
General Description
The DS89C386 is a high speed twelve channel CMOS differ-
ential receiver that meets the requirements of TIA/
EIA-422-B. The DS89C386 features low power dissipation of
240 mW typical.
Each TRI-STATE
廬
enable, EN, allows the receiver output to
be active or in a Hi-impedance off state. Each enable is com-
mon to only two receivers for flexibility and multiplexing of re-
ceiver outputs.
The receiver output (RO) is guaranteed to be High when the
inputs are left open and unterminated. The receiver can de-
tect signals as low and including
鹵
200 mV over the common
mode range of
鹵
7V. The receiver outputs (RO) are compat-
ible with both TTL and CMOS levels.
