Note 15:
R
= 50
termination resistive load. When an input or output is being monitored by a scope, R
T
is supplied by the scope’s 50
input resistance. When
an input or output is not being monitored, an external 50
resistance must be applied to serve as R
T
.
Note 16:
TTL and ECL force signals are brought to the DUT via 50
coax lines.
Note 17:
V
TTL
is decoupled to ground with 0.1 μF, V
EE
is decoupled to ground with 0.01 μF and V
CC
is connected to ground.
