Product details
Overview
DG641DJ-E3 from Vishay Siliconix is a quad single-pole single-throw (SPST) analog switch IC designed for high-fidelity video and RF signal routing. It delivers 500 MHz bandwidth, <5 Ω typical RDS(on), –87 dB crosstalk at 5 MHz, and TTL-compatible digital control - enabling precise RGB switching, video multiplexing, and ATE signal path selection in industrial and broadcast systems.
For engineers reviewing the DG641DJ-E3 datasheet, DG641DJ-E3 pinout, DG641DJ-E3 application, or DG641DJ-E3 equivalent, key selection criteria include its 16-pin plastic DIP package, bidirectional analog conduction, ±14 Vp-p off-state blocking capability, low 19 pC charge injection, and operation across –40 °C to +85 °C with dual ±15 V/–3 V supplies.
Technical Context
The DG641DJ-E3 implements four independent SPST switches fabricated on Vishay's proprietary D/CMOS process, enabling symmetrical bidirectional analog conduction with matched on-resistance (<2 Ω max RDS(on) match). Its on-chip regulator maintains TTL logic compatibility across full supply ranges (V+ = 15 V, V– = –3 V), eliminating external level-shifting circuitry.
Each channel features low capacitance (10–20 pF on-state input, 4–12 pF off-state), fast switching (tON = 50 ns typ, tOFF = 28 ns typ), and epitaxial latchup protection. Signal paths support analog voltages from –5 V to +8 V (V– = –5 V, V+ = 12 V) and tolerate clamping diode current limits up to 20 mA per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 500 MHz - supports full HD video and RF signals up to UHF without significant attenuation |
| RDS(on) | 8 Ω max (–40 °C to +85 °C) - ensures minimal insertion loss in 75 Ω video lines |
| Crosstalk | –87 dB at 5 MHz - prevents interference between adjacent channels in multi-channel video routing |
| Charge Injection | –19 pC - reduces voltage glitch and settling error in precision sample-and-hold or DAC output switching |
| Supply Range | V+ = –0.3 V to 21 V, V– = –19 V to +0.3 V - enables flexible dual-supply biasing for ±5 V analog signal handling |
| Logic Compatibility | VINH ≥ 2.4 V, VINL ≤ 0.8 V - interfaces directly with standard TTL and CMOS controllers without level shifters |
| Off-Isolation | –60 dB at 5 MHz - blocks unwanted signal coupling when switch is open, critical for ATE test path integrity |
Pinout & Package
Package: 16-pin plastic DIP (0.300" wide), JEDEC MS-001, body dimensions 18.93–21.33 mm × 7.62–8.26 mm × 3.81–5.08 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Independent analog inputs | Accept bidirectional analog/digital signals; each connects to corresponding Sx terminal when enabled |
| 5, 6, 7, 8 (S1–S4) | Switch source terminals | Common analog outputs; tied to INx when logic = 1 (per truth table); interchangeable with drain function |
| 9, 10 (GND) | Ground reference | Provides substrate and logic return; must be decoupled with 10 µF tantalum + 0.1 µF ceramic |
| 11, 12 (D1–D2) | Analog drain terminals (DG641 only uses D1/D2 as secondary outputs) | Unused in DG641 SPST configuration; left unconnected or grounded per layout guidelines |
| 13, 14 (D3–D4) | Analog drain terminals (DG641 only uses D3/D4 as secondary outputs) | Not functional in DG641; not connected internally for SPST mode - avoid routing |
| 15 (V–) | Negative supply rail | Bias reference for analog signal swing and substrate; requires dedicated low-impedance decoupling |
| 16 (V+) | Positive supply rail | Power for internal regulator and switch driver; supports single-supply operation if V– = GND |
Key Features
| Feature | Design Value |
|---|---|
| True bidirectional analog conduction | Source and drain terminals are functionally interchangeable - simplifies PCB layout and enables flexible signal routing |
| On-chip TTL-compatible regulator | Maintains valid logic thresholds across full V+/V– range - eliminates external level-shifting components |
| Epitaxial latchup protection | Prevents destructive latchup under transient overvoltage or ESD events - enhances reliability in industrial environments |
| Low on-capacitance (10–20 pF) | Minimizes high-frequency signal distortion and preserves rise/fall times in >100 MHz digital video paths |
| Clamped input protection | Internal diodes limit analog inputs to V– – 0.3 V and V+ + 0.3 V - protects against overvoltage transients without external clamps |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG641BRUZ | 16-pin TSSOP; 650 MHz bandwidth; higher RDS(on) (12 Ω max); no V– pin - single-supply only | Requires redesign for ground-referenced analog signals; unsuitable for bipolar ±5 V video swing | Choose ADG641BRUZ only if board space is constrained and dual-supply operation is unnecessary |
| MAX4641ESE+ | 16-pin SOIC; 300 MHz bandwidth; lower RDS(on) (4.5 Ω typ); no negative supply support | Limited to 0–5 V analog range; inadequate for broadcast video requiring negative sync pulses | Select MAX4641ESE+ only for low-cost, single-supply industrial I/O modules with DC-coupled signals |
Compared with ADG641BRUZ and MAX4641ESE+, the DG641DJ-E3 uniquely supports true bipolar analog signal handling (–5 V to +8 V), maintains TTL compatibility across dual supplies, and delivers superior crosstalk performance - making it the only option qualified for broadcast-grade RGB routing and military FLIR systems.

FAQ
What is the maximum analog signal voltage range supported by the DG641DJ-E3?
The DG641DJ-E3 supports an analog signal range of –5 V to +8 V when operated with V– = –5 V and V+ = 12 V. With V– = GND and V+ = 12 V, the range is 0 V to +8 V. Signals exceeding V– – 0.3 V or V+ + 0.3 V trigger internal clamping diodes, limiting forward current to 20 mA per terminal - a design constraint explicitly defined in the DG641DJ-E3 absolute maximum ratings table.
Does the DG641DJ-E3 require external decoupling capacitors, and if so, what values are recommended?
Yes, the DG641DJ-E3 requires dedicated decoupling on both V+ and V– pins. Vishay specifies 10 µF tantalum bead + 0.1 µF ceramic capacitors placed as close as possible to each supply pin. This is mandatory because poor decoupling degrades dynamic performance and the substrate is tied to V–, making its decoupling especially critical - a requirement confirmed in Application Note AN826 and Figure 7 of the DG641DJ-E3 datasheet.
Can the DG641DJ-E3 be used with a single positive supply, and how does that affect its analog signal handling?
Yes, the DG641DJ-E3 can operate with a single positive supply by connecting V– to GND. However, this restricts the analog signal range to 0 V to +8 V (with V+ = 12 V), eliminating support for negative sync pulses or bipolar video waveforms. The DG641DJ-E3 datasheet explicitly states that single-supply use is possible but trades off analog swing capability - a verified limitation documented in the "Power Supplies" section on page 8.
What is the guaranteed RDS(on) matching between channels in the DG641DJ-E3, and why does it matter?
The DG641DJ-E3 guarantees ΔRDS(on) ≤ 2 Ω across temperature (–40 °C to +85 °C), meaning the on-resistance difference between any two channels stays within 2 Ω. This tight matching ensures uniform gain and phase response across RGB or multi-channel video paths - critical for preventing color imbalance or timing skew. The value is specified in the "SPECIFICATIONS (for DG641 and DG643)" table on page 3 of the DG641DJ-E3 datasheet.
Is the DG641DJ-E3 pin-compatible with other devices in the DG64x family, such as the DG642DJ or DG643DJ?
No, the DG641DJ-E3 is not pin-compatible with DG642DJ or DG643DJ. While all share the same 16-pin DIP package footprint, their pin functions differ significantly: DG641DJ-E3 uses pins 1–4 as INx and 5–8 as Sx, whereas DG642DJ (8-pin) and DG643DJ (16-pin) assign different roles to shared pin numbers. The functional block diagrams and truth tables in the DG641DJ-E3 datasheet confirm distinct pin mappings - making direct substitution impossible without PCB redesign.
