... SCSI terminator chip. Therefore essential to maintain the proper enable signal to the switchable terminator even during peripheral power down. To avoid rendering the system inoperable while powering down a terminating peripheral, ON Semiconductor has an exclusive “Local V which latches the enable state of the termination permanently during peripheral power loss. A comparator within the MCCS142235 can be connected to the local http://onsemi ...
