DG444B, DG445B Datasheet

DG444B, DG445B
Vishay Siliconix
Improved Quad SPST CMOS Analog Switches
DESCRIPTION
FEATURES
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.
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.
The DG444B, DG445B are built using Vishay Siliconix’s
high-voltage silicon-gate process. An epitaxial layer prevents
latchup.
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.
