Product details

Overview

DG453EQ-T1-E3 from Vishay Siliconix is a high-voltage quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, 4 Ω typical on-resistance, ±15 V analog signal range, and 44 V supply rating-designed for precision audio/video switching and relay replacement in industrial test equipment.

For engineers reviewing the DG453EQ-T1-E3 datasheet, DG453EQ-T1-E3 pinout, DG453EQ-T1-E3 application, or DG453EQ-T1-E3 equivalent, key selection criteria include break-before-make timing (70 ns at +12 V), on-resistance flatness (0.25 Ω typical), charge injection (1 pC at +12 V), and TSSOP-16 RoHS-compliant packaging for space-constrained PCB layouts.

Technical Context

The DG453EQ-T1-E3 implements a CMOS-based dual-supply (±5 V to ±15 V) or single-supply (up to 12 V) analog switch architecture with independent digital control inputs per channel pair. Its internal structure supports bidirectional conduction, rail-to-rail analog signal handling, and TTL/CMOS-compatible logic thresholds (0.8 V low, 2.4 V high).

Unlike the DG451 (all-NC) and DG452 (all-NO), the DG453EQ-T1-E3 integrates two NO and two NC switches in one die-enabling simultaneous make/break sequencing critical for signal path redundancy and fault-tolerant routing in data acquisition systems.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance	5.5 Ω typical at +12 V supply - ensures minimal insertion loss in 50 Ω video/audio paths
On-resistance flatness	0.94 Ω typical across 0–10 V signal swing - preserves THD < 0.04 % in precision audio
Break-before-make delay	70 ns at +12 V - prevents momentary shorting during channel switching in multiplexer designs
Charge injection	1 pC at +12 V - limits voltage glitch to < 1 mV in 1 nF sample-hold nodes
Analog signal range	0 to +12 V (unipolar) or ±15 V (dual) - supports full-rail operation in instrumentation front-ends
Switching speed	t_ON = 132 ns / t_OFF = 61 ns at +12 V - enables >5 MHz video bandwidth with < −60 dB off-isolation
ESD protection	2 kV HBM - meets IEC 61000-4-2 Level 2 for board-level robustness

Pinout & Package

TSSOP-16 package (JEDEC MS-012), 4.4 mm × 5.0 mm × 1.2 mm body, 0.65 mm pitch, RoHS-compliant matte tin lead finish.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4 (IN1–IN4)	Digital control inputs	Active-high logic controls SW1–SW4; IN1/IN2 drive NC switches, IN3/IN4 drive NO switches
5, 6, 13, 14 (S1–S4)	Source terminals	Common analog input nodes; S1/S2 tied to NC outputs, S3/S4 to NO outputs
7, 8, 11, 12 (D1–D4)	Drain terminals	Switched analog outputs; D1/D2 are NC outputs, D3/D4 are NO outputs
9 (V−)	Negative supply rail	Accepts −15 V max; required for dual-supply operation and rail-to-rail signal swing
10 (GND)	Ground reference	Logic ground return; isolated from analog signal path to minimize coupling noise
15 (V+)	Positive supply rail	Accepts +44 V max; supplies internal switch bias and defines upper analog rail
16 (VL)	Logic supply	Separate 5 V rail powers input buffers-decouples logic noise from analog performance

Key Features

Feature	Design Value
Two-NO/two-NC configuration	Enables fail-safe signal routing: e.g., default path via NC switches, active path via NO switches
Break-before-make timing	Guaranteed 70 ns delay prevents cross-conduction in redundant signal path switching
Rail-to-rail analog operation	Supports ±15 V or 0–12 V signals without clipping-critical for ±10 V data acquisition front-ends
Ultra-low power dissipation	18 µW typical - allows battery-powered portable test gear with negligible thermal impact
Pin compatibility with DG411/412/413	Enables drop-in upgrade from legacy Vishay switches without PCB redesign

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX4532ESE+	Higher on-resistance (12 Ω typ), no break-before-make guarantee, SOIC-16 only	Limited to lower-precision audio; unsuitable for fault-tolerant NO/NC sequencing	Select when cost sensitivity outweighs flatness and timing control requirements
ADG1434BRUZ	Lower on-resistance (3.8 Ω typ), but only all-NO configuration, higher supply current (20 µA vs. 0.001 µA)	Cannot replicate DG453EQ-T1-E3's mixed NO/NC topology for safety-critical path redundancy	Prefer for ultra-low R_ON in high-speed data acquisition where topology flexibility is secondary

Compared with MAX4532ESE+ and ADG1434BRUZ, the DG453EQ-T1-E3 uniquely delivers verified break-before-make timing, mixed NO/NC topology, and sub-1 pC charge injection-making it the only choice for fault-aware analog multiplexing in medical instrumentation and avionics signal conditioning.

FAQ

What is the maximum supply voltage rating for DG453EQ-T1-E3?

The DG453EQ-T1-E3 has an absolute maximum V+ to V− rating of 44 V. It operates fully specified at dual supplies of ±5 V, ±15 V, or single supply of 12 V. Exceeding these limits risks permanent damage per Absolute Maximum Ratings table in Document 74470.

Does DG453EQ-T1-E3 support rail-to-rail analog signal switching?

Yes, DG453EQ-T1-E3 supports rail-to-rail analog operation: ±15 V with dual supplies or 0 to +12 V with single supply. Internal clamping diodes limit signal excursions beyond rails, but forward current must stay within 30 mA per Absolute Maximum Ratings.

How does the two-NO/two-NC configuration of DG453EQ-T1-E3 differ from DG451EQ-T1-E3?

DG453EQ-T1-E3 integrates two normally closed (S1/D1, S2/D2) and two normally open (S3/D3, S4/D4) switches. In contrast, DG451EQ-T1-E3 contains four NC switches only. This mixed topology enables fail-safe default paths and active redundancy-unavailable in DG451EQ-T1-E3.

What is the guaranteed break-before-make delay for DG453EQ-T1-E3?

The DG453EQ-T1-E3 guarantees a 70 ns break-before-make time delay at +12 V supply (T_A = 25 °C), measured per Figure 2 in Document 74470. This parameter ensures no overlap between NC and NO channel conduction during logic transitions.

Is DG453EQ-T1-E3 pin-compatible with older Vishay analog switches?

Yes, DG453EQ-T1-E3 is pin-compatible with DG411, DG412, and DG413 per datasheet Document 74470. This allows direct replacement in existing SOIC-16 or TSSOP-16 layouts without PCB modification-retaining identical pin functions and footprint.
