Product details
Overview
DG612DJ-E3 from Vishay Siliconix is a high-speed, low-glitch quad SPST analog switch IC with CMOS-compatible control logic, 12 ns turn-on time, 18 Ω on-resistance, and ±2 pC charge injection - deployed in fast sample-and-hold circuits and pixel-rate video switching.
For engineers reviewing the DG612DJ-E3 datasheet, DG612DJ-E3 pinout, DG612DJ-E3 application, or DG612DJ-E3 equivalent, key selection criteria include bipolar supply support (V+ = 5–21 V, V− = −10 to 0 V), 500 MHz bandwidth, low off-isolation (74 dB at 5 MHz), and DIP-16 package compatibility for legacy test and instrumentation designs.
Technical Context
The DG612DJ-E3 implements four independent bidirectional SPST switches built on Vishay's proprietary D/CMOS process, integrating n-channel DMOS FETs with low-power CMOS drivers and latchup-preventing epitaxial isolation. Each switch conducts equally in both directions when on and blocks up to 16 Vp-p when off.
It uses complementary logic control versus DG611 (logic "0" = ON, logic "1" = OFF), features 5 V CMOS-compatible input thresholds (VIL ≤ 1 V, VIH ≥ 4 V), and operates across −40 °C to +85 °C with single- or split-supply configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open, complementary to DG611 |
| Turn-On Time (tON) | 12 ns @ RL = 300 Ω, CL = 3 pF - enables sub-100 ns aperture uncertainty in sampling |
| On-Resistance (RDS(on)) | 18 Ω typical @ VS = 0 V - ensures minimal insertion loss in 50 Ω signal paths |
| Charge Injection | ±2 pC max - limits step error in precision sample-and-hold hold capacitors |
| Bandwidth | 500 MHz - supports full NTSC/PAL video and GaAs FET RF switching without roll-off |
| Supply Range | V+ = 5–21 V, V− = −10 to 0 V - allows flexible bipolar operation for analog front-ends |
| Off Isolation (OIRR) | 74 dB @ 5 MHz - suppresses crosstalk between adjacent video or RF channels |
Pinout & Package
Package: 16-pin plastic DIP (JEDEC MS-012), 0.300″ wide, RoHS-compliant with -E3 suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | CMOS-compatible logic; INx = LOW → corresponding switch ON (DG612 logic polarity) |
| 5, 6, 13, 14 (S1–S4) | Source terminals | Bidirectional analog current path; connect to signal source or load side |
| 7, 8, 11, 12 (D1–D4) | Drain terminals | Bidirectional analog current path; paired with Sx for SPST channel conduction |
| 9 (V−) | Negative supply rail | Supports split-supply operation down to −10 V; clamps analog signals below V− − 0.3 V |
| 10 (V+) | Positive supply rail | Accepts 5–21 V; defines upper analog signal limit (V+ − 5 V) and internal bias |
| 15 (GND) | Analog/digital reference ground | Common return for supplies and logic; must be low-impedance for low-glitch performance |
| 16 (VL) | Logic supply voltage | Separate 4–V+ rail for input buffers; decouples logic noise from analog path |
Key Features
| Feature | Design Value |
|---|---|
| Low-glitch architecture | Minimizes transient energy during switching via matched charge injection and fast tON/tOFF symmetry |
| Wide analog signal range | VANALOG = V− to (V+ − 5 V) - supports ±5 V, ±10 V, and unipolar 0–12 V systems |
| High off-isolation & low crosstalk | OIRR = 74 dB, XTalk = 87 dB @ 5 MHz - preserves signal integrity in multi-channel video routing |
| Low quiescent power | 1.2 nW typical - enables battery-powered portable test equipment and low-power instrumentation |
| Robust ESD protection | Exceeds 2 kV HBM - reduces field failure risk in handling and board assembly |
Applications
| Fast Sample-and-Hold Circuits | Pixel-Rate Video Switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPD+ | Single-supply only (2.7–12 V); 35 ns tON; 35 Ω RDS(on); no V− rail | Not suitable for bipolar analog signal ranges or −10 V head selection; limited to unipolar industrial I/O | Select when cost-sensitive, single-rail 5 V systems dominate and speed >12 ns is acceptable |
| ADG1412BRUZ | 4-channel, 1.5 Ω RDS(on), 17 ns tON, ±15 V analog range, but requires VDD/VSS rails and higher quiescent current (20 µA) | Superior on-resistance for precision instrumentation, but higher power and tighter layout constraints due to LFCSP package | Select when ultra-low RDS(on) and rail-to-rail analog swing outweigh DIP-16 footprint and nW power needs |
Compared with MAX4617CPD+ and ADG1412BRUZ, the DG612DJ-E3 uniquely balances nanosecond switching, bipolar supply flexibility, DIP-16 through-hole compatibility, and sub-nW quiescent power - making it optimal for legacy test gear, video infrastructure, and mixed-signal systems where layout stability and supply versatility are critical.

FAQ
What is the logic polarity of DG612DJ-E3 compared to DG611DJ-E3?
The DG612DJ-E3 uses inverted logic control: a logic LOW (≤1 V) turns each switch ON, while a logic HIGH (≥4 V) turns it OFF. This is the exact opposite of DG611DJ-E3, which activates switches on HIGH. Both share identical analog performance, pinout, and supply requirements - enabling direct substitution in existing layouts when logic inversion is accommodated in firmware or upstream logic.
Can DG612DJ-E3 operate from a single 5 V supply?
Yes, DG612DJ-E3 supports single-supply operation: configure V+ = 5 V, V− = GND (pin 9 tied to pin 15), and VL = 5 V. In this mode, the analog signal range is 0 V to 2 V (V+ − 3 V minimum headroom), and RDS(on) increases to ~25 Ω. Full 500 MHz bandwidth and low charge injection remain valid, making it viable for 3.3 V/5 V digital systems interfacing to baseband analog paths.
What is the maximum allowable analog signal voltage swing for DG612DJ-E3?
The DG612DJ-E3 supports analog signals from V− to (V+ − 5 V). With V+ = 15 V and V− = −3 V, the usable range is −3 V to +10 V (13 Vp-p). Exceeding these limits forward-biases internal clamping diodes - limiting absolute analog voltage to (V− − 0.3 V) ≤ VS/VD ≤ (V+ + 0.3 V), with current restricted to 20 mA per terminal to avoid damage.
Does DG612DJ-E3 require external bypass capacitors?
Yes - stable operation requires 0.1 µF ceramic capacitors between V+ and GND, V− and GND, and VL and GND, placed within 5 mm of the respective pins. These suppress supply transients induced by fast switching (12 ns edges), preventing logic upset and reducing charge injection-induced glitches. Omitting them degrades off-isolation by up to 20 dB and increases tON variation across temperature.
Is DG612DJ-E3 pin-compatible with other DG61x variants in DIP-16 package?
Yes - DG611DJ-E3, DG612DJ-E3, and DG613DJ-E3 share identical DIP-16 pinouts and footprints. The DG613 adds internal SPDT configuration capability but retains the same terminal mapping for S/D/IN/V+/V−/GND/VL pins. No PCB redesign is needed when upgrading from DG612DJ-E3 to DG613DJ-E3, though logic sequencing and truth table interpretation differ per device function.
