Product details

Overview

DG611DJ from Vishay Siliconix is a high-speed, low-glitch quad SPST analog switch IC designed for precision signal routing in fast-switching systems. It features 12 ns turn-on time, 18 Ω on-resistance, ±2 pC charge injection, 500 MHz bandwidth, and operates from dual supplies (V+ = 5–21 V, V− = −10 to 0 V). It is used in pixel-rate video switching and DAC deglitching where minimal transient error and wide analog bandwidth are critical.

For engineers reviewing the DG611DJ datasheet, DG611DJ pinout, DG611DJ application, or DG611DJ equivalent, key selection criteria include guaranteed 12 ns t_ON, low R_DS(on) matching across channels, logic-level compatibility with 5 V CMOS, and validated performance under −40 °C to +85 °C industrial temperature range.

Technical Context

The DG611DJ implements four independent SPST switches built on Vishay's proprietary D/CMOS process, integrating n-channel DMOS FETs with low-power CMOS control logic and on-chip level translators. Each switch conducts bidirectionally when enabled and blocks up to 16 V_p-p when off.

Its architecture minimizes parasitic capacitance (C_S(on) = 10 pF, C_D(off) = 2 pF) and charge injection (±2 pC typical), enabling clean switching transients essential for fast sample-and-hold and synchronous demodulator circuits operating at multi-MHz rates.

Key Specifications

Parameter	Value and Actual Design Meaning
t_ON	12 ns - Enables sub-83 MHz switching cycles without aperture uncertainty in sampling systems.
R_DS(on)	18 Ω typical - Ensures low insertion loss and minimal signal attenuation in 50 Ω video or RF paths.
Charge injection	±2 pC - Limits step-induced offset errors in precision sample-and-hold and switched-capacitor filters.
Bandwidth	500 MHz - Supports full-spectrum integrity for composite video, GaAs driver control, and pixel-rate signals.
Analog range	V− to (V+ − 5) V - Allows rail-to-rail analog signal handling with 15 V/−3 V supplies (e.g., −3 V to +10 V).
Logic threshold	V_IL ≤ 1 V, V_IH ≥ 4 V - Directly interfaces with standard 5 V CMOS without level-shifting circuitry.
Off isolation	74 dB at 5 MHz - Suppresses crosstalk between active and inactive channels in multi-source video switching.

Pinout & Package

DG611DJ is housed in a 16-pin plastic DIP package (JEDEC MS-012), 10.0 mm × 4.0 mm footprint, 3.81 mm height, with 2.54 mm lead pitch. Pin 1 is top-left corner (notch side), pin 16 bottom-right.

Pin/Terminal	Circuit Role	Design Meaning
IN1–IN4	Digital control inputs	Active-high logic enables corresponding SPST switch; compatible with 5 V CMOS levels (0 V/5 V).
S1–S4	Switch source terminals	Analog input nodes; bidirectional conduction path when associated INx = high.
D1–D4	Switch drain terminals	Analog output nodes; symmetric with Sx-no channel directionality required.
V+	Positive analog supply	Bias for DMOS FETs; supports up to +21 V; sets upper analog signal limit.
V−	Negative analog supply	Bias for DMOS FETs; supports down to −10 V; sets lower analog signal limit.
VL	Logic supply reference	Defines logic threshold; must be ≥4 V and ≤V+; decouples digital control from analog rails.
GND	Ground reference	Common return for logic and substrate; separate from analog ground in mixed-signal layouts.

Key Features

Feature	Design Value
Four independent SPST switches	Enables discrete routing of four analog signals without shared control or signal path interference.
Low glitch energy	Minimizes transient voltage spikes during switching-critical for DAC output stabilization and video overlay timing.
Epitaxial latchup prevention	Ensures robust operation in high-noise industrial environments with rapid supply transients or ESD events.
Low quiescent power	1.2 nW typical - Reduces system standby current and thermal load in battery-backed or dense PCB layouts.
Single-supply operable	Supports unipolar analog operation (e.g., V+ = 15 V, V− = 0 V) while maintaining full 0–7 V analog range.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4617ESE+	Single 2-channel SPDT; 100 Ω R_DS(on); 300 MHz bandwidth; 3.3 V logic only.	Not suitable for quad SPST or 5 V logic interface; limited to low-voltage, low-bandwidth routing.	Select only if board space is constrained and 100 Ω on-resistance is acceptable.
ADG1419BRUZ	Quad SPST; 1.3 Ω R_DS(on); 170 MHz bandwidth; 15 V max supply; 3 V logic compatible.	Superior on-resistance but lower bandwidth; not rated for −10 V V−; requires external level shifters for 5 V logic.	Prefer for ultra-low-loss audio or precision instrumentation; avoid for >200 MHz video or GaAs gate drive.

Compared with MAX4617ESE+ and ADG1419BRUZ, DG611DJ uniquely balances 12 ns speed, 500 MHz bandwidth, 5 V logic compatibility, and quad SPST topology-making it optimal for pixel-rate video, DAC deglitching, and high-frequency GaAs driver applications where timing fidelity and signal integrity are non-negotiable.

FAQ

What is the maximum analog signal voltage range supported by DG611DJ?

DG611DJ supports an analog signal range from V− to (V+ − 5) V. With recommended operating conditions of V+ = 15 V and V− = −3 V, the usable analog range is −3 V to +10 V. Absolute maximum ratings allow V+ to V− up to 21 V, but the functional analog swing remains bounded by the (V+ − 5) upper limit to ensure proper switch operation and prevent internal clamp diode conduction.

Does DG611DJ require separate logic and analog ground connections?

No-DG611DJ uses a single GND pin for both logic and substrate reference. However, best practice for high-fidelity analog switching is to maintain separate analog and digital ground planes joined at a single point near the DG611DJ GND pin to minimize noise coupling. The VL pin provides logic-level referencing independent of analog supplies, reducing sensitivity to V+ or V− ripple.

Can DG611DJ operate from a single 15 V supply?

Yes-DG611DJ supports unipolar operation: set V− = 0 V, V+ = 15 V, VL = 5 V. In this configuration, the analog signal range becomes 0 V to +10 V (since VANALOG = V− to (V+ − 5)). All dynamic specifications-including 12 ns t_ON, 18 Ω R_DS(on), and 500 MHz bandwidth-remain valid per the unipolar supply test conditions documented in the datasheet.

How does DG611DJ differ from DG612DJ and DG613DJ?

DG611DJ has active-high logic control (INx = high → switch ON); DG612DJ is identical except with active-low logic (INx = low → switch ON). DG613DJ integrates two normally open and two normally closed switches, enabling configurable SPST/SPDT/DPDT topologies-unlike the fixed quad SPST architecture of DG611DJ. Pinouts and truth tables differ across all three variants.

Is DG611DJ RoHS compliant?

DG611DJ-E3 is the RoHS-compliant version with lead-free terminations. Standard DG611DJ carries Pb-containing terminations and is not RoHS compliant unless explicitly ordered with the "-E3" suffix. Both versions share identical electrical and thermal specifications; only the finish and compliance status differ.
