Transition Socket Specification
SSOP TRANSITION SOCKET
An SSOP transition socket and associated hardware is
shown in Figure 2.
FIGURE 2: SSOP TRANSITION SOCKET
The SSOP transition sockets are similar to the SOIC
transition sockets. There are two parts to the SSOP
transition socket:
1. Adapter socket that connects to the DIP device
adapter.
2. SSOP header that gets soldered down to the
target application.
Microchip offers the following SSOP transition sockets:
• XLT14SS-1: One 14-lead DIP adapter socket and
one 14-lead SSOP header
• XLT20SS-1: One 18-lead DIP adapter socket and
one 20-lead SSOP header
• XLT20SS1-1: One 20-lead DIP adapter socket
and one 20-lead SSOP header
• XLT28SS-1: One 28-lead DIP adapter socket and
one 28-lead SSOP header
• XLT28SS2-1: One 28-lead DIP adapter socket
and one 28-lead SSOP header (PIC16X55/57)
See the drawings in this section for layout dimensions
and clearances for tall components.
