NAME
FUNCTION
MAX4936/
MAX4938
MAX4937/
MAX4939
41
LVCC4
Inductor VCC Connection. Connect an inductor between LVCC4 and VCC to
improve noise performance; otherwise, connect LVCC4 to VCC.
42
LVEE3
Inductor VEE Connection. Connect an inductor between LVEE3 and VEE to
improve noise performance; otherwise, connect LVEE3 to VEE.
43
NO3
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.
44
LVCC3
Inductor VCC Connection. Connect an inductor between LVCC3 and VCC to
improve noise performance; otherwise, connect LVCC3 to VCC.
45
LVEE2
Inductor VEE Connection. Connect an inductor between LVEE2 and VEE to
improve noise performance; otherwise, connect LVEE2 to VEE.
46
NO2
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
limited with clamping diodes on MAX4936/MAX4937.
47
LVCC2
Inductor VCC Connection. Connect an inductor between LVCC2 and VCC to
improve noise performance; otherwise, connect LVCC2 to VCC.
48
LVEE1
Inductor VEE Connection. Connect an inductor between LVEE1 and VEE to
improve noise performance; otherwise, connect LVEE1 to VEE.
49
NO1
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.
50
LVCC1
Inductor VCC Connection. Connect an inductor between LVCC1 and VCC to
improve noise performance; otherwise, connect LVCC1 to VCC.
51
LE
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.
52
CLR
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.
55
COM1
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.
56
—
HV1
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.
—
EP
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.
