PA17C42-DP(-PP) Data Sheet
40 pin DIP socket/44 pin PLCC plug
Supported Device/Footprints
The PA17C42-DP adapter accepts 40 pin DIP devices and plugs
into 44 pin PLCC production sockets. This allows DIP devices,
or emulators with DIP plugs, to be used during development of
PLCC based products.
The PA17C42-DP-PP has a production socket only.

Adapter Construction
The adapter is made up of 2 sub-assemblies. They assemble via
connectors making the adapter modular. This way the sub-
assemblies can be replaced when they wear out.
When disassembling the adapter take care not to bend the pins.
When reassembling the adapter note the pin 1 indicators to align
the parts correctly.
Test Socket
