Product details
Overview
DG452EY-T1-E3 from Vishay Siliconix is a high-voltage quad SPST analog switch with normally open (NO) configuration, 4 Ω typical on-resistance, ±15 V analog signal range, and 44 V supply maximum rating-designed for precision audio switching in industrial test equipment.
For engineers reviewing the DG452EY-T1-E3 datasheet, DG452EY-T1-E3 pinout, DG452EY-T1-E3 application, or DG452EY-T1-E3 equivalent, key selection criteria include on-resistance flatness (0.2 Ω typ), charge injection (22 pC), break-before-make timing (DG453 only), and compatibility with ±5 V, ±15 V, or 12 V single-supply operation.
Technical Context
The DG452EY-T1-E3 implements four independent CMOS SPST switches with inverted digital control logic (logic 0 = ON, logic 1 = OFF), enabling precise bidirectional analog signal routing across rail-to-rail input ranges up to ±15 V. Each switch supports 100 mA continuous current and exhibits ultra-low power dissipation (18 µW).
It operates fully specified at dual supplies (±5 V, ±15 V) and unipolar 12 V, with TTL/CMOS-compatible inputs (0.8 V/2.4 V thresholds), ESD protection (2 kV HBM), and pin compatibility with DG412 and DG451/DG453 variants in the same family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 4 Ω typical - ensures minimal signal attenuation and distortion in low-level audio paths |
| On-resistance flatness | 0.2 Ω typical - maintains consistent gain and THD across full analog voltage swing (±15 V) |
| Switching speed | ton = 80 ns, toff = 60 ns - supports video-rate signal routing without visible artifacts |
| Analog signal range | ±15 V - enables direct interfacing with op-amp outputs and sensor front-ends without level-shifting |
| Supply voltage max | 44 V - accommodates high-voltage industrial and avionics signal chains |
| Charge injection | 22 pC - limits voltage glitch in sample-and-hold and multiplexed ADC applications |
| Off-isolation | -60 dB at 1 MHz - suppresses crosstalk between adjacent channels in dense PCB layouts |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012, body width 3.9 mm, lead pitch 1.27 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control input | Inverted logic: low = switch ON (NO configuration); compatible with 3.3 V/5 V logic |
| S1–S4 | Source terminal | Analog input/output node; bidirectional conduction when switch is ON |
| D1–D4 | Drain terminal | Analog input/output node; equal conduction capability as Sx pins |
| V+, V− | Analog supply rails | Support dual ±15 V or unipolar 12 V operation; define analog signal swing limits |
| GND | Ground reference | Return path for logic supply (VL) and substrate bias; separate from analog ground |
| VL | Logic supply | Independent 5 V supply for digital interface-decoupled from analog rails to prevent noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Inverted NO logic control | Enables active-low enable architecture in safety-critical or fail-safe systems where default state must be open |
| Rail-to-rail analog conduction | Signals from V− to V+ pass unclamped-eliminates need for external clamping diodes in ±15 V systems |
| Ultra-low power dissipation | 18 µW typical - reduces thermal drift and enables battery-powered portable instrumentation |
| Pin compatibility with DG412 | Allows drop-in replacement in legacy designs using DG412-based PCBs without layout changes |
| TTL/CMOS input thresholds | 0.8 V low / 2.4 V high - ensures reliable switching with standard microcontroller GPIOs and FPGA I/O banks |

FAQ
What is the maximum analog signal voltage range supported by DG452EY-T1-E3?
DG452EY-T1-E3 supports an analog signal range of ±15 V when operated with dual ±15 V supplies, and 0 V to +12 V with unipolar 12 V supply. Signals exceeding V+ or V− are clamped by internal diodes-forward current must be limited per datasheet Note a.
Is DG452EY-T1-E3 pin-compatible with DG412EY-T1-E3?
Yes, DG452EY-T1-E3 is pin-compatible with DG412EY-T1-E3 in the 16-pin narrow SOIC package. Both share identical pinout, footprint, and logic interface-but DG452EY-T1-E3 provides significantly improved on-resistance (4 Ω vs. 35 Ω) and switching speed (80 ns vs. 200 ns).
Does DG452EY-T1-E3 require a separate logic supply voltage?
Yes, DG452EY-T1-E3 requires VL = 5 V for its digital control inputs. This logic supply is electrically isolated from the analog V+/V− rails, reducing noise coupling and enabling mixed-signal system partitioning. VL must be decoupled with a 0.1 µF capacitor near the pin.
What is the typical charge injection value for DG452EY-T1-E3, and why does it matter?
DG452EY-T1-E3 has a typical charge injection of 22 pC. This parameter determines the voltage glitch injected into a sampled capacitor during switching-critical in sample-and-hold circuits and multiplexed ADC front-ends where low settling error is required.
Can DG452EY-T1-E3 operate from a single 12 V supply?
Yes, DG452EY-T1-E3 is fully specified for unipolar 12 V operation (V+ = 12 V, V− = 0 V), supporting analog signals from 0 V to +10 V. On-resistance is 5.5 Ω typical under these conditions, and switching times are 132 ns (tON) and 61 ns (tOFF).
