DESCRIPTION
The DG417L/418L/419L are low voltage pin-for-pin compat-
ible companion devices to the industry standard DG417/418/
419 with improved performance.
Using BiCMOS wafer fabrication technology allows the
DG417L/418L/419L to operate on single and dual supplies.
Single supply voltage ranges from 3 to 12 V while dual sup-
ply operation is recommended with ± 3 to ± 6 V.
Combining high speed (tON: 28 ns), flat rON over the analog
signal range (6 Ω), minimal insertion lose (up to 100 MHz),
and excellent crosstalk and off-isolation performance (- 70 dB
at 1 MHz), the DG417L/418L/419L are ideally suited for audio
and video signal switching.
The DG417L and DG418L respond to opposite control logic
as shown in the Truth Table. The DG419L has an SPDT con-
figuration.

Notes:
a. Leakage parameters are guaranteed by worst case test condition and not subject to production test.
b. Room = 25 °C, Full = as determined by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
e. Guaranteed by design, not subject to production test.
f. VIN = input voltage to perform proper function.
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.
