DG9421, DG9422
Vishay Siliconix
Precision Low-Voltage, Low-Glitch CMOS Analog Switches
DESCRIPTION
Using BiCMOS wafer fabrication technology allows the
DG9421, DG9422 to operate on single and dual supplies.
Designed for optimal performance at single 5 V and dual
± 5 V, the DG9421, DG9422 combine low and flat
on-resistance (3 Ω), fast speed (tON = 38 ns) and is well
suited for applications where signal switching accuracy, low
noise and low distortion is critical.
The DG9421 and DG9422 respond to opposite control logic
as shown in the Truth Table.
FEATURES
• 2.7- thru 12 V single supply or
± 2.7- thru ± 6-dual supply
• Low on-resistance - RDS(on): 2.0 Ω at 12 V
• Fast switching - tON: 28 ns
•
- tOFF: 22 ns
• TTL and low voltage logic
• Low leakage: 10 pA (typ.)
• > 2000 V ESD protection
BENEFITS
• High accuracy
• High speed, low glitch
• Single and dual supply capability
• Low RON in small TSOP package
• Low leakage
• Low power consumption
APPLICATIONS
• Automatic test equipment
• Data acquisition
• XDSL and DSLAM
• PBX systems
• Reed relay replacement
• Audio and video signal routing
