MIC5204
SCSI-II Active Terminator
Preliminary Information
General Description
The MIC5204 is an active terminator designed to comply with
SCSI-II specifications. The MIC5204 is enabled by a CMOS
or TTL compatible logic signal. When disabled, power
consumption drops nearly to zero and the output goes into a
high impedance state. Key MIC5204 features include protec-
tion against reversed battery, current limiting, and over-
temperature shutdown.
