| 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 ), 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 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 Pb-free Available RoHS* COMPLIANT 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 FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION TSOP-6 V+ COM V1 2 3 Top View Device Marking: DG9421DV = 4Exxx 6 5 4 IN NC GND TRUTH TABLE Logic 0 1 DG9421 ON OFF DG9422 OFF ON Logic "0" 0.8 V Logic "1" 2.4 V Switches Shown for Logic "0" Input TSOP-6 V+ COM V1 2 3 Top View Device Marking: DG9422DV = 4Fxxx 6 5 4 IN NO GND ORDERING INFORMATION Temp.

Refer to PROCESS OPTION FLOWCHART. 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. g. Leakage parameters are guaranteed by worst case test conditions and not subject to test. 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. Document Number: 70679 S-82265-Rev.
