Vishay Siliconix DG213DJ

Overview

DG213DJ from Vishay Siliconix is a quad complementary CMOS analog switch with two normally closed (NC) and two normally open (NO) SPST switches, rated for ±22 V dual-supply operation, featuring 45 Ω typical on-resistance, 85 ns turn-on time, and 1 pC charge injection - used in precision sample-and-hold circuits and industrial instrumentation signal routing.

For engineers reviewing the DG213DJ datasheet, DG213DJ pinout, DG213DJ application, or DG213DJ equivalent, key selection criteria include bi-directional analog signal handling up to ±22 V, low leakage (<5 nA), TTL/CMOS-compatible control logic, and DIP-16 package compatibility with legacy test equipment designs.

Technical Context

The DG213DJ implements four independent analog switches arranged as two NC and two NO configurations, enabling flexible topologies including SPST, SPDT, T-switch, and DPDT. Its proprietary high-voltage silicon gate CMOS process delivers matched rDS(on) (≤2 Ω max mismatch) and latchup immunity via epitaxial isolation.

Switching is controlled by complementary logic inputs (IN1–IN4), where logic "0" disables SW1/SW4 and enables SW2/SW3, and logic "1" reverses state. Level-shifting circuitry allows VL = 5 V logic supply while operating across V+ = +15 V and V− = −15 V analog rails.

FAQ

What is the maximum analog signal voltage range supported by the DG213DJ?

The DG213DJ supports analog signals from V− to V+, with absolute maximum ratings of ±22 V across the V+ and V− pins. Under continuous operation, it handles ±3 V to ±22 V dual supplies, enabling rail-to-rail signal conduction without clipping - confirmed in the Absolute Maximum Ratings and Specifications tables of Vishay document 70662.

Does the DG213DJ require separate logic and analog ground connections?

Yes - the DG213DJ has dedicated GND (pin 10) for logic-level references and VL (pin 14) for logic supply, while V+ and V− serve analog rails. The datasheet specifies separation of digital and analog grounds to minimize noise coupling, especially critical in high-resolution measurement systems using the DG213DJ.

Can the DG213DJ operate from a single positive supply?

Yes - the DG213DJ supports unipolar operation from +3 V to +40 V (V− tied to GND), with verified specifications including 90 Ω typical rDS(on) and 125 ns tON at V+ = 12 V. This mode is explicitly covered in the "SPECIFICATIONS for Unipolar Supply" section of the DG213DJ datasheet (document 70662, page 4).

What is the purpose of the VL pin on the DG213DJ?

The VL pin (pin 14) supplies the internal level-shifting circuitry that translates 5 V TTL/CMOS logic inputs to the high-voltage analog domain. It decouples logic interface voltage from V+ and V−, allowing safe control of ±22 V analog paths using standard 5 V microcontrollers - a key feature documented in the Functional Block Diagram and Truth Table sections of the DG213DJ datasheet.

Is the DG213DJ RoHS compliant?

The DG213DJ is leaded (Pb-containing) and not RoHS compliant per Vishay documentation; however, the RoHS-compliant version DG213DJ-E3 is available as a direct-orderable alternative. Both share identical electrical and mechanical specifications except for termination finish - confirmed in the Ordering Information table on page 2 of document 70662.
