DG444B, DG445B  
Vishay Siliconix  
Improved Quad SPST CMOS Analog Switches  
FEATURES  
DESCRIPTION  
Halogen-free according to IEC 61249-2-21  
Definition  
The DG444B, DG445B are monolithic quad analog switches  
designed to provide high speed, low error switching of analog  
and audio signals. The DG444B, DG445B are upgrades to  
the original DG444, DG445.  
Low On-Resistance: 45 W  
Low Power Consumption: 1 mW  
Fast Switching Action - tON: 120 ns  
Low Charge Injection  
TTL/CMOS-Compatible Logic  
Compliant to RoHS Directive 2002/95/EC  
Combing low on-resistance (45 , typ.) with high speed  
(tON 120 ns, typ.), the DG444B, DG445B are ideally suited  
for Data Acquisition, Communication Systems, Automatic  
Test Equipment, or Medical Instrumentation. Charge  
injection has been minimized on the drain for use in  
sample-and-hold circuits.  
BENEFITS  
Low Signal Errors and Distortion  
Reduced Power Supply Consumption  
Faster Throughput  
Reduced Pedestal Errors  
Simple Interfacing  
The DG444B, DG445B are built using Vishay Siliconix’s  
high-voltage silicon-gate process. An epitaxial layer prevents  
latchup.  
APPLICATIONS  
When on, each switch conducts equally well in both  
directions and blocks input voltages to the supply levels  
when off.

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

Dimensioning and tolerancing conform to ASME Y14.5M-1994.  
All dimensions are in millimeters. All angels are in degrees.  
N is the total number of terminals.  
The terminal #1 identifier and terminal numbering convention shall conform to JESD 95-1 SPP-012. Details of terminal #1 identifier are optional, but must  
be located within the zone indicated. The terminal #1 identifier may be either a molded or marked feature. The X and Y dimension will vary according to  
lead counts.

Dimension b applies to metallized terminal and is measured between 0.25 mm and 0.30 mm from the terminal tip.  
ND and NE refer to the number of terminals on the D and E side respectively.  
Depopulation is possible in a symmetrical fashion.  
Variation HHD is shown for illustration only.  
Coplanarity applies to the exposed heat sink slug as well as the terminals.
