MAX4939
24 24 CLK Serial-Clock Input
25 25 DIN Serial-Data Input
26 26 DOUT Serial-Data Output
27 27 LVCC8
Inductor V
CC
Connection. Connect an inductor between LVCC8 and V
CC
to
improve noise performance, otherwise connect LVCC8 to V
CC
.
28 28 NO8
T/R Switch 8 Output. When the switch is on, low-voltage signals are passed
through from COM8 to NO8, while high-voltage signals are blocked. When the
switch is off, both low-voltage and high-voltage signals are blocked. NO8 is
limited with clamping diodes on MAX4936/MAX4937.
29 29 LVEE8
Inductor V
EE
Connection. Connect an inductor between LVEE8 and V
EE
to
improve noise performance; otherwise, connect LVEE8 to V
EE
.
30 30 LVCC7
Inductor V
CC
Connection. Connect an inductor between LVCC7 and V
CC
to
improve noise performance; otherwise, connect LVCC7 to V
CC
.
31 31 NO7
T/R Switch 7 Output. When the switch is on, low-voltage signals are passed
through from COM7 to NO7, while high-voltage signals are blocked. When the
switch is off, both low-voltage and high-voltage signals are blocked. NO7 is
limited with clamping diodes on MAX4936/MAX4937.
32 32 LVEE7
Inductor V
EE
Connection. Connect an inductor between LVEE7 and V
EE
to
improve noise performance; otherwise, connect LVEE7 to V
EE
.
33 33 LVCC6
Inductor V
CC
Connection. Connect an inductor between LVCC6 and V
CC
to
improve noise performance; otherwise, connect LVCC6 to V
CC
.
34 34 NO6
T/R Switch 6 Output. When the switch is on, low-voltage signals are passed
through from COM6 to NO6, while high-voltage signals are blocked. When the
switch is off, both low-voltage and high-voltage signals are blocked. NO6 is
limited with clamping diodes on MAX4936/MAX4937.
35 35 LVEE6
Inductor V
EE
Connection. Connect an inductor between LVEE6 and V
EE
to

CC
.
37 37 NO5
T/R Switch 5 Output. When the switch is on, low-voltage signals are passed
through from COM5 to NO5, while high-voltage signals are blocked. When the
switch is off, both low-voltage and high-voltage signals are blocked. NO5 is
limited with clamping diodes on MAX4936/MAX4937.
38 38 LVEE5
Inductor V
EE
Connection. Connect an inductor between LVEE5 and V
EE
