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.

NO4

T/R Switch 4 Output. When the switch is on, low-voltage signals are passed

through from COM4 to NO4, while high-voltage signals are blocked. When the

switch is off, both low-voltage and high-voltage signals are blocked. NO4 is

limited with clamping diodes on MAX4936/MAX4937.
