DESCRIPTION
FEATURES
The DG9424, DG9425, DG9426 are low voltage precision
monolithic quaꢀ single-pole-single-throw analog switches.
•
•
•
2.7 V thru 12 V single supply or 3 thru 6 ꢀual supply
On-resistance - RDS(on): 1.7 Ω
Fast switching - tON: 42 ns
- tOFF: 28 ns
Using BiCMOS wafer fabrication technology allows the
DG9424, DG9425, DG9426 to operate on single anꢀ ꢀual
supplies. Single supply voltage ranges from 3 to 12 V while
ꢀual supply operation is recommenꢀeꢀ with 3 to 6 V.
•
•
•
TTL, CMOS compatible
Low leakage: 0.2 nA
2000 V ESD protection
Combining high speeꢀ (tON: 42 ns), flat RDS(on) over the
analog signal range (Ω), minimal insertion lose (- 3 ꢀB at
190 MHz), anꢀ excellent crosstalk anꢀ off-isolation
performance, the DG9424, DG9425, DG9426 are iꢀeally
suiteꢀ for auꢀio anꢀ viꢀeo signal switching.
BENEFITS
•
•
•
•
Wiꢀest ꢀynamic range
Low signal errors anꢀ ꢀistortion
Break-before-make switching action
Simple interfacing
The DG9424 anꢀ DG9425 responꢀ to opposite control logic
as shown in the Truth Table. The DG9426 has two normally
open anꢀ two normally closeꢀ switches.
APPLICATIONS

Notes:
a. Leakage parameters are guaranteeꢀ by worst case test conꢀitions anꢀ not subject to proꢀuction test.
b. Room = 25 °C, Full = as ꢀetermineꢀ by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteeꢀ nor subject to proꢀuction testing.
ꢀ. The algebraic convention whereby the most negative value is a minimum anꢀ the most positive a maximum, is useꢀ in this ꢀata sheet.
e. Guaranteeꢀ by ꢀesign, not subject to proꢀuction 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.
