DG417L/DG418L/DG419L
General Description
The DG417L/DG418L/DG419L precision, CMOS analog switches feature low on-resistance (RON = 35Ω),
guaranteed R ON matching between switches (3Ω
max), and guaranteed RON flatness over the signal
range (4Ω max). These switches are +3V logic-compatible when powered from ±15V or ±12V supplies.
The switches conduct equally well in either direction,
and feature low charge injection and low power consumption. The DG417L/DG418L/DG419L also offer low
off-leakage current over temperature (less than 5nA at
+85°C).
The DG417L/DG418L are single-pole/single-throw
(SPST) switches. The DG417L is normally closed, and
the DG418L is normally open. The DG419L is singlepole/double-throw (SPDT) with one normally closed
switch and one normally open switch. Switching times
are less than 175ns for tON and less than 185ns for
tOFF. These devices operate with a single +9V to +36V
or bipolar ±4.5V to ±20V supplies.

Note 1: Signals on COM, NO, or NC exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current
ratings.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3: -40°C specifications are guaranteed by design.
Note 4: Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured at the
extremes of the specified analog range.
Note 5: Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at TA = +25°C.
Note 6: Guaranteed by design.
Note 7: Off-isolation = 20log10 [VCOM / (VNC or VNO)], VCOM = output, VNC or VNO = input to off switch.

Power-Supply
Sequencing-Free Operation
Most CMOS switches require specific power-supply
sequencing in order to prevent device latchup. The
older DG417/DG418/DG419 devices require a proper
power-supply sequence of V+, VL, then V-. Otherwise,
it is necessary to add signal diodes to the circuit in
order to prevent potential latchups. The new
DG417L/DG418L/DG419L devices eliminate the need
for a VL input and allow any power-up sequence. Do
not exceed the absolute maximum ratings because
stresses beyond the listed ratings may cause permanent damage to the devices.
