Notes: 1) Control Signals: each card shall present a load to the socket no larger than 50 pF
state and 150
while meeting all AC timing requirements: (the number of sockets wired in parallel) multiplied by (50 pF with DC
current 700
2) Resistor is optional.
3) Status Signals: the socket shall present a load to the card no larger than 50 pF
and 100
