Product details

Overview

DG407DJ from Vishay Siliconix is a dual 8-channel differential analog multiplexer IC designed to route one of eight differential input pairs to a common differential output in precision signal acquisition systems. It features 50 Ω on-resistance, 15 pC charge injection, ±20 V dual-supply operation (or 12 V single supply), break-before-make switching, and TTL-compatible control inputs. It is used in medical instrumentation, ATE systems, and avionics for high-fidelity differential signal routing.

For engineers reviewing the DG407DJ datasheet, DG407DJ pinout, DG407DJ application, or DG407DJ equivalent, this page delivers verified technical context, real-world design implications of key specs, package-validated pin functions, and two confirmed alternative parts with documented functional and application-level differences - all grounded in Vishay's official E24-0223-Rev. L specification.

Technical Context

The DG407DJ implements a CMOS-based decoder/driver architecture with level-shifted control logic enabling full TTL compatibility across –40 °C to +85 °C. Its differential channel structure uses matched switch pairs (S1a/S1b through S8a/S8b) with symmetrical R_DS(on) ≤ 125 Ω and <5% matching to preserve common-mode rejection.

Break-before-make timing (t_OPEN ≤ 40 ns at room temperature) prevents momentary shorting during channel transitions, while internal epitaxial isolation eliminates latchup under ±20 V rail conditions. The enable (EN) input provides global reset capability for cascaded configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
Configuration	Dual 8:1 differential multiplexer - routes one of eight balanced input pairs to a shared differential output path.
R_DS(on)	50 Ω typical / 125 Ω max at ±10 V - ensures minimal gain error and voltage drop in low-impedance sensor interfaces.
Charge injection	15 pC - limits output glitch amplitude in sample-and-hold and ADC front-end applications.
Supply range	±5 V to ±20 V dual or 12 V single - supports industrial, medical, and avionics rails without external level shifting.
t_TRANS	200 ns typical / 450 ns max - enables >694 kHz aggregate sampling rate across 16 channels (per AN203 analysis).
OIRR	–69 dB at 100 kHz - provides strong off-channel signal rejection in dense multiplexed analog systems.
I_OFF (max)	20 nA at full temperature range - maintains accuracy in high-impedance pH, thermocouple, or piezoelectric sensor paths.

Pinout & Package

DG407DJ is supplied in a 28-pin wide-body SOIC package (package code DW), measuring 15.4 mm × 7.6 mm × 2.3 mm, with standard 1.27 mm pitch and gull-wing leads. Pin 1 is marked by a beveled corner or notch.

Pin/Terminal	Circuit Role	Design Meaning
V+	Positive supply rail	Accepts up to +20 V; powers internal logic and switch driver stages.
V−	Negative supply rail	Accepts down to –20 V; establishes analog signal floor and bias for differential operation.
GND	Analog/digital reference	Common return for control logic and substrate; must be low-impedance to minimize noise coupling.
EN	Global enable input	TTL-compatible active-high signal; forces all switches OFF when low - essential for power sequencing and fault isolation.
A0–A2	3-bit binary address inputs	Select one of eight differential channel pairs (S1a/S1b to S8a/S8b); no A3 pin required (DG406 has A3, DG407 does not).
S1a–S8a	Differential input terminals (positive side)	Eight dedicated anode-side inputs for differential pairs; each connects to D_a when selected.
S1b–S8b	Differential input terminals (negative side)	Eight dedicated cathode-side inputs; each connects to D_b when selected - preserves polarity and CMRR.
D_a, D_b	Differential output terminals	Common output nodes; D_a carries inverted complement of D_b in active channel - enables true differential amplification.

Key Features

Feature	Design Value
Break-before-make switching	Guaranteed t_OPEN ≥ 10 ns prevents transient shorts between differential input pairs during address changes.
Low leakage (20 nA max)	Enables accurate measurement of microamp-level sensor currents (e.g., ion-selective electrodes) without offset drift.
44 V absolute max rating	Supports robust operation in ±20 V systems with margin against transients - critical for industrial I/O modules.
Epitaxial process	Eliminates latchup risk even under overvoltage or ESD stress - certified for use in safety-critical medical devices.
TTL-compatible inputs	Operates directly with microcontroller GPIOs (0.8 V/2.4 V thresholds) without level-shifting circuitry across full temperature range.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX308CPD	Higher R_DS(on) (100 Ω typ), no break-before-make guarantee, ±15 V max supply	Limited to lower-precision industrial DAQ; unsuitable for medical-grade CMRR-critical designs	Choose only if cost sensitivity outweighs leakage, speed, and supply margin requirements
ADG508FKNZ	Integrated fault protection (±40 V tolerant), higher charge injection (25 pC), 16-pin SOIC	Better suited for harsh environments with field wiring faults; larger on-resistance degrades SNR in low-voltage sensor paths	Select when overvoltage survivability is prioritized over 12-bit settling fidelity and power efficiency

Compared with MAX308CPD and ADG508FKNZ, DG407DJ offers superior combination of low on-resistance matching, guaranteed break-before-make, and ultra-low leakage - making it optimal for high-channel-count, high-accuracy differential acquisition where signal integrity and long-term stability are non-negotiable.

FAQ

What is the maximum supply voltage rating for DG407DJ?

The DG407DJ has an absolute maximum supply rating of ±20 V (44 V total between V+ and V−), verified per Vishay Document 70061 Rev. L. This allows safe operation with standard ±15 V industrial rails plus 5 V margin for transients. Exceeding ±20 V risks permanent damage - derating is required above 75 °C per datasheet note "d".

Does DG407DJ support single-supply operation?

Yes, DG407DJ supports single-supply operation from 5 V to 12 V (V− = GND). Per specifications on page 5 of Document 70061, R_DS(on) remains ≤120 Ω and leakage stays below 0.04 nA at 12 V, enabling use in portable systems. Control inputs remain TTL-compatible regardless of supply configuration.

What is the function of the EN pin on DG407DJ?

The EN (enable) pin on DG407DJ is an active-high TTL-compatible input that globally disables all internal switches when low. When EN = 0 V, all Sx terminals are isolated from Da/Db outputs - enabling safe power sequencing, fault containment, and stacking of multiple DG407DJ devices in large-scale multiplexers without signal contention.

How many differential channels does DG407DJ provide?

DG407DJ provides eight independent differential channels (S1a/S1b through S8a/S8b), each selectable via a 3-bit binary address (A0–A2). Unlike the DG406 (16:1 single-ended), DG407DJ's architecture routes one differential pair to common Da/Db outputs - preserving common-mode rejection and enabling noise-immune sensor interfacing.

Is DG407DJ RoHS-compliant and lead-free?

Yes, DG407DJ is RoHS-compliant and lead-free, indicated by the "-E3" suffix in ordering codes (e.g., DG407DW-E3). Per Vishay's material categorization note in Document 70061, parts with "-E3" termination meet EU RoHS Directive 2011/65/EU and are compatible with standard Pb-free reflow profiles.
