Product details

Overview

DG452EQ-T1-E3 from Vishay Siliconix is a high-voltage quad SPST analog switch with normally open (NO) configuration, designed for bidirectional signal routing in precision analog systems. It delivers 4 Ω typical on-resistance, ±15 V analog signal range, and 100 mA continuous current handling across dual ±15 V or single 12 V supplies - enabling low-distortion audio switching and relay replacement in industrial test equipment.

For engineers reviewing the DG452EQ-T1-E3 datasheet, DG452EQ-T1-E3 pinout, DG452EQ-T1-E3 application, or DG452EQ-T1-E3 equivalent, key selection criteria include on-resistance flatness (0.2 Ω typical), fast switching (80 ns t_ON/60 ns t_OFF), TTL/CMOS compatibility, and TSSOP-16 packaging for high-density PCB layouts.

Technical Context

The DG452EQ-T1-E3 implements four independent CMOS transmission gates with inverted digital control logic relative to DG451 (NO vs NC). Each switch conducts equally in both directions and supports rail-to-rail analog signals up to ±15 V or 0–12 V, with internal clamping diodes limiting input excursions beyond V+ or V−.

It operates with ultra-low power dissipation (18 µW typical) and features guaranteed 2 kV HBM ESD protection. All digital inputs meet standard TTL/CMOS thresholds (0.8 V low / 2.4 V high), ensuring interoperability with microcontroller GPIOs and logic families without level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance	4 Ω typical at ±15 V supply - enables minimal insertion loss in audio/video paths and precision data acquisition channels
On-resistance flatness	0.2 Ω typical - ensures consistent THD (<0.04%) across full analog voltage swing for high-fidelity signal routing
Analog signal range	±15 V - supports full-rail operation with dual supplies, eliminating need for external biasing in bipolar signal chains
Switching speed	t_ON = 80 ns, t_OFF = 60 ns - suitable for video-rate multiplexing and fast automatic test equipment sequencing
Continuous current	100 mA per channel - allows direct driving of moderate-load sensors, transducers, or relay coils without buffering
ESD rating	2 kV HBM - provides robust handling during board assembly and field service without additional protection circuitry
Supply voltage max	44 V (V+ to V−) - accommodates wide-range industrial power rails and transient-tolerant designs

5, 6, 13, 14 (S1–S4)	Source terminals	Analog inputs/outputs; bidirectional conduction when enabled; rated for ±15 V or 0–12 V signals
7, 8, 11, 12 (D1–D4)	Drain terminals	Analog inputs/outputs; electrically identical to sources; matched R_ON and capacitance
9 (V−)	Negative supply rail	Reference for negative analog swing; must be connected even in unipolar operation
10 (GND)	Ground reference	Logic ground and substrate reference; separate from analog signal return paths
15 (V+)	Positive supply rail	Supports up to +16.5 V; defines upper analog voltage limit and internal bias generation
16 (VL)	Logic supply	Independent 2.7–5.5 V supply for digital interface; decoupling required for noise immunity

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4522ESE+	Higher on-resistance (100 Ω typical), lower supply voltage (±5 V max), SOIC-16 only	Better suited for low-voltage portable instrumentation; not viable for ±15 V or 12 V systems	Select when cost sensitivity outweighs performance; avoid where rail-to-rail analog range is required
ADG1412BRUZ	Lower on-resistance (1.3 Ω), higher bandwidth (170 MHz), but requires ≥±4.5 V supplies and has no 12 V unipolar support	Ideal for high-speed data acquisition with FPGA interfaces; lacks DG452EQ-T1-E3's 12 V single-supply flexibility	Prefer for >10 MSPS sampling systems; verify compatibility with existing ±15 V infrastructure before substitution

Compared with MAX4522ESE+ and ADG1412BRUZ, the DG452EQ-T1-E3 uniquely balances 4 Ω on-resistance, ±15 V/12 V dual-mode operation, and TSSOP-16 compactness - making it optimal for space-constrained industrial test gear requiring wide analog range and low distortion.

FAQ

What is the maximum analog signal voltage range supported by the DG452EQ-T1-E3?

The DG452EQ-T1-E3 supports an analog signal range of ±15 V when operated with dual ±15 V supplies, and 0–12 V with a single 12 V supply. Signals exceeding V+ or V− are clamped by internal diodes; forward current must be limited to rated values. This range is confirmed in the Absolute Maximum Ratings and Dual Supply Specifications tables of Vishay Document 74470.

Is the DG452EQ-T1-E3 pin-compatible with older Vishay analog switches?

Yes, the DG452EQ-T1-E3 is pin-compatible with the DG412 and DG451 series, as explicitly stated in the datasheet's Features and Functional Block Diagram sections. This allows direct replacement in existing SOIC-16 or TSSOP-16 layouts without PCB modification, provided supply and logic voltage conditions match.

What is the typical on-resistance flatness of the DG452EQ-T1-E3, and why does it matter?

The DG452EQ-T1-E3 has a typical on-resistance flatness of 0.2 Ω across the full analog signal range. This parameter quantifies variation in R_ON versus input voltage - critical for minimizing harmonic distortion in audio and precision measurement applications. Low flatness directly enables <0.04% THD performance as verified in the datasheet's Dynamic Characteristics table.

Can the DG452EQ-T1-E3 operate from a single 5 V supply?

No - the DG452EQ-T1-E3 requires either dual supplies (e.g., ±5 V, ±15 V) or a single 12 V supply. The datasheet specifies no operational characterization for 5 V unipolar use. Attempting 5 V single-supply operation would violate the minimum V+–V− differential (4 V typical) and compromise analog range, on-resistance, and switching speed.

What package type is used for the DG452EQ-T1-E3, and what are its key mechanical dimensions?

The DG452EQ-T1-E3 uses a 16-pin TSSOP package (JEDEC MS-012), with body dimensions of 5.0 mm × 4.4 mm and maximum height of 1.2 mm. Lead pitch is 0.65 mm, and recommended pad dimensions are provided in Vishay Document 63550. This compact footprint supports high-density PCB layouts while maintaining thermal derating capability up to +85 °C ambient.
