Product details

Overview

DG408DY-T1-E3 from Vishay Siliconix is an 8-channel single-ended CMOS analog multiplexer with TTL-compatible control logic, designed to route one of eight analog inputs to a common output under 3-bit binary address (A0–A2) and enable (EN) control. It delivers 100 Ω on-resistance, 20 pC charge injection, and 160 ns transition time, supporting ±5 V to ±20 V dual supplies or +5 V to +36 V single supply - ideal for high-speed data acquisition and battery-powered instrumentation.

For engineers reviewing the DG408DY-T1-E3 datasheet, DG408DY-T1-E3 pinout, DG408DY-T1-E3 application, or DG408DY-T1-E3 equivalent, this page provides 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.

Technical Context

The DG408DY-T1-E3 implements break-before-make switching to prevent crosstalk during channel transitions, with all channels blocking voltages up to the supply rails in the off state and conducting bidirectionally when on. Its silicon-gate CMOS process enables 44 V absolute maximum supply rating and latchup immunity via epitaxial layer protection.

Control inputs (A0, A1, A2, EN) are TTL-compatible across –40 °C to +85 °C, with logic "0" ≤ 0.8 V and logic "1" ≥ 2.4 V. The device supports stacking via EN-driven global disable, allowing multiple units to share a common output bus without contention.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance	100 Ω max - ensures minimal signal attenuation and gain error in precision analog paths
Charge injection	20 pC typ - limits voltage glitch at output during channel switching, critical for sample-and-hold stability
Transition time	160 ns typ - enables >5 MHz multiplexed signal throughput in data acquisition systems
Supply range	+5 V to +36 V single or ±5 V to ±20 V dual - supports wide industrial and medical rail configurations
Off leakage current	±5 nA max at full temperature range - preserves signal integrity in high-impedance sensor interfaces
Enable timing	ton(EN) = 150 ns max, toff(EN) = 150 ns max - allows tight synchronization in multi-device mux trees
Off isolation	–75 dB min at 1 MHz - suppresses crosstalk between inactive channels in dense routing applications

Pinout & Package

DG408DY-T1-E3 is supplied in a 16-pin narrow SOIC (SO-16) package per JEDEC MS-012, with 1.27 mm pitch, body dimensions 9.9 mm × 3.9 mm × 1.45 mm, and lead finish RoHS-compliant matte tin (–E3 suffix).

Pin	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 8	Analog inputs S1–S8	Eight bidirectional analog signal terminals; each connects to common output D when selected
9	Ground (GND)	Reference node for digital logic and internal level shifters; must be tied to system ground
10	V−	Negative supply rail; sets lower bound of analog signal range and powers internal circuitry
11	V+	Positive supply rail; sets upper bound of analog signal range and powers internal circuitry
12	EN	Active-high enable input; forces all switches open when low, enabling multi-device stacking
13	A0	LSB address bit; selects channel index modulo 2 in conjunction with A1 and A2
14	A1	Mid-bit address input; determines channel pair selection with A0 and A2
15	A2	MSB address bit; selects one of two groups of four channels
16	D	Common analog output/summing node; carries selected Sx signal bidirectionally

Key Features

Feature	Design Value
Break-before-make switching	Guarantees no momentary short between adjacent channels, eliminating transient crosstalk in audio and sensor routing
Single-supply operation	Operates from +5 V to +36 V - eliminates need for dual-rail supplies in portable and industrial systems
44 V absolute max rating	Withstands transient overvoltage events up to 44 V differential without damage, enhancing field reliability
TTL-compatible inputs	Accepts standard 0.8 V / 2.4 V logic thresholds across full –40 °C to +85 °C range - simplifies interface to microcontrollers and FPGAs
Low power consumption	10 μA typical supply current - extends battery life in remote data loggers and handheld test equipment

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4051ACPE+	8:1 single-ended mux; 125 Ω R_DS(on) max, 25 pC charge injection, ±15 V max dual supply	Higher on-resistance and charge injection limit use in <16-bit precision or >100 kSPS DAQ systems	Prefer DG408DY-T1-E3 where <100 Ω R_DS(on) and <20 pC Q are required for metrology-grade accuracy
ADG1408BRUZ	8:1 mux with 4.7 Ω R_DS(on), but requires ≥ ±4.5 V dual supply or ≥ 9 V single supply; 100 mA continuous current rating	Optimized for low-R_DS(on) power switching, not low-leakage precision sensing; higher supply demand	Choose DG408DY-T1-E3 for battery operation, wide supply range, or sub-5 nA leakage-critical designs

Compared with MAX4051ACPE+ and ADG1408BRUZ, DG408DY-T1-E3 uniquely balances ultra-low leakage (±5 nA), wide supply flexibility (+5 V to +36 V), and moderate on-resistance (100 Ω) - making it optimal for portable, multi-range, and high-isolation analog routing where power, voltage headroom, and crosstalk matter more than sub-10 Ω conduction.

FAQ

What is the maximum supply voltage rating for DG408DY-T1-E3?

DG408DY-T1-E3 has an absolute maximum supply voltage rating of 44 V across V+ and V− terminals. This rating applies to both single-supply (e.g., V+ = 44 V, V− = GND) and dual-supply (e.g., V+ = +22 V, V− = –22 V) configurations. Operation beyond this limit risks permanent damage, even if within recommended operating ranges.

Does DG408DY-T1-E3 support single-supply operation?

Yes, DG408DY-T1-E3 supports true single-supply operation from +5 V to +36 V, with V− connected to GND. In this mode, the analog signal range extends from 0 V to V+, and all specifications - including R_DS(on), charge injection, and leakage - remain valid per the datasheet's single-supply test conditions.

What is the function of the EN pin on DG408DY-T1-E3?

The EN (enable) pin on DG408DY-T1-E3 is an active-high control that globally disables all eight analog switches when driven low. When EN = 0 V, no channel connects to D regardless of A0–A2 state - enabling safe stacking of multiple DG408DY-T1-E3 devices on a shared output bus without signal contention.

How does DG408DY-T1-E3 handle overvoltage conditions on analog inputs?

DG408DY-T1-E3 clamps analog inputs exceeding V+ or V− via internal diodes. To avoid forward conduction, external series current limiting (≤20 mA) is required. For robust overvoltage protection, Vishay recommends adding 1N4148 diodes in series with V+ and V− rails - extending survivability while preserving low R_DS(on) and leakage performance.

Is DG408DY-T1-E3 RoHS-compliant and lead-free?

Yes, the –E3 suffix in DG408DY-T1-E3 explicitly denotes lead-free, RoHS-compliant construction with matte tin lead finish. This part meets EU RoHS Directive 2011/65/EU and is categorized under Vishay's material compliance framework per doc#99912.
