Transition Socket Specification
SSOP TRANSITION SOCKET
An SSOP transition socket and associated hardware is
shown in Figure 3.
FIGURE 3: SSOP TRANSITION SOCKET
The SSOP transition sockets are similar to the SOIC
transition sockets. There are two parts to the SSOP
transition socket:
1.
2.
The following SSOP transition sockets have been dis-
continued:
• XLT14SS: One adapter socket and three 14-lead
• XLT20SS: One adapter socket and three 20-lead
• XLT20SS1: One adapter socket and three 20-lead
• XLT28SS: One adapter socket and three 28-lead
• XLT28SS2: One adapter socket and three 28-lead
See the drawings in this section for layout dimensions
and clearances for tall components.

Adapter socket that connects to the PDIP device
adapter.
SSOP header that gets soldered down to the
target application.
To keep the leads straight during assembly
and shipping, the SSOP headers are
shipped with break-away tabs attached to
the leads. Please remove the break-away
tabs before applying power to the target
system. Be careful not to bend the leads
prior to soldering to the target application.
