MDP1645 Schematic

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.

MDP1646 Schematic

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.
