T/R Switch 3 Output. When the switch is on, low-voltage signals are passed
through from COM3 to NO3, while high-voltage signals are blocked. When the
switch is off, both low-voltage and high-voltage signals are blocked. NO3 is
limited with clamping diodes on MAX4936/MAX4937.

T/R Switch 2 Output. When the switch is on, low-voltage signals are passed
through from COM2 to NO2, while high-voltage signals are blocked. When the
switch is off, both low-voltage and high-voltage signals are blocked. NO2 is

T/R Switch 1 Output. When the switch is on, low-voltage signals are passed
through from COM1 to NO1, while high-voltage signals are blocked. When the
switch is off, both low-voltage and high-voltage signals are blocked. NO1 is
limited with clamping diodes on MAX4936/MAX4937.

Active-Low Latch-Enable Input. Drive LE low to change the contents of the latch
and update the state of the switches. Drive LE high to hold the contents of the
latch.
Active-High Latch-Clear Input. Drive CLR high to clear the contents of the latch
and disable all the switches. When CLR is driven high, the device enters
shutdown mode. CLR does not affect the contents of the register.
T/R Switch 1 Input. When the switch is on, low-voltage signals are passed
through from COM1 to NO1, while high-voltage signals are blocked. When the
switch is off, both low-voltage and high-voltage signals are blocked.
T/R Switch 1 Input. COM1 follows HV1 when high-voltage signals are present on
HV1. HV1 is isolated from COM1 when low-voltage signals are present on COM1.
Exposed Pad. Internally connected to GND. Connect EP to a large ground plane
to maximize thermal performance. Do not use EP as the only GND connection.
