CIRCUIT APPLICATIONS

TTL to ECL translator

The MDP1645 network consists of 18 resistors of 3 different values,

internally divided into six (6) identical three (3) resistor sections for

TTL to ECL translation.

SCSI-BUS signal terminator

The MDP1646 network consists of 21 resistors of 2 different values,

internally divided into seven (7) identical three (3) resistor sections for

SCSI-BUS terminator applications.
