Product details
Overview
DG9233EDQ-T1-GE3 from Vishay Siliconix is a dual normally-open (NO) monolithic CMOS analog switch IC, designed for precision signal routing in low-voltage instrumentation and medical systems. It delivers 17 Ω typical on-resistance at 5 V, 1 pC charge injection, 100 pA max on-leakage at 25 °C, and operates from +2.7 V to +5.5 V - enabling high-fidelity switching in ADC front-ends and sample-and-hold circuits.
For engineers reviewing the DG9233EDQ-T1-GE3 datasheet, DG9233EDQ-T1-GE3 pinout, DG9233EDQ-T1-GE3 application, or DG9233EDQ-T1-GE3 equivalent, key selection criteria include guaranteed low leakage (<100 pA), sub-35 ns switching speed, MSOP-8 package compatibility, and break-before-make timing not applicable (as DG9233E is dual-NO with independent control).
Technical Context
The DG9233EDQ-T1-GE3 implements two independent single-pole single-throw (SPST) switches, both normally open - activated by logic-high control inputs (≥2.4 V). Each switch supports bidirectional analog/digital signal conduction with rail-to-rail voltage handling up to V+ and blocking capability to supply rails when off.
Its architecture minimizes signal distortion via low parasitic capacitance (3.8 pF off, 7.8 pF on), flat on-resistance vs. analog voltage (±3.5 Ω variation), and tightly matched RDS(on) (ΔRDS(on) ≤ 2 Ω), making it suitable for precision gain-setting and multiplexed sensor interfaces where channel-to-channel consistency is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(on)) | 17 Ω typ. at 5 V - ensures minimal signal attenuation and gain error in precision analog paths |
| Charge injection | 1 pC max - reduces sampling glitches in data acquisition and sample-and-hold applications |
| Switch leakage (on-state) | 100 pA max at 25 °C - preserves accuracy in high-impedance sensor and medical electrode interfaces |
| Switching time (tON/tOFF) | 32 ns / 10 ns typ. at 5 V - supports >10 MHz multiplexing without timing bottlenecks |
| Supply range | +2.7 V to +5.5 V - enables direct interface with 3.3 V and 5 V logic and mixed-supply systems |
| ESD tolerance | 8 kV HBM, 1 kV CDM - enhances robustness during board assembly and field operation |
| Off-isolation (OIRR) | −80 dB at 1 MHz - suppresses crosstalk between adjacent channels in dense analog routing |
Pinout & Package
Package: 8-lead MSOP (JEDEC MO-187, variation AA/BA), 3.00 mm × 4.90 mm footprint, 0.65 mm pitch, exposed pad optional per design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC1) | No-connect terminal | Internally unconnected; must be left floating or tied to GND per layout best practice |
| 2 (V+) | Positive supply rail | Accepts +2.7 V to +5.5 V; decoupling capacitor required within 1 cm for stable switching |
| 3 (COM1) | Common terminal of Switch-1 | Bidirectional path; connects to load or signal source depending on NO1/IN1 state |
| 4 (IN1) | Control input for Switch-1 | Logic-high (≥2.4 V) closes Switch-1; logic-low (≤0.8 V) opens it - NO configuration |
| 5 (IN2) | Control input for Switch-2 | Independent logic control identical to IN1; enables asynchronous dual-channel switching |
| 6 (COM2) | Common terminal of Switch-2 | Electrically isolated from COM1; supports separate signal paths without coupling |
| 7 (GND) | Ground reference | Return path for supply and logic; must share common ground plane with V+ decoupling |
| 8 (NC2) | No-connect terminal | Internally unconnected; no routing or soldering required |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent SPST switches, both normally open | Enables discrete control of two signal paths without interdependence or break-before-make delay |
| Guaranteed 100 pA max on-leakage at 25 °C | Maintains integrity of microamp-level biomedical signals and high-impedance transducer outputs |
| 1 pC max charge injection | Minimizes voltage step errors during sampling, critical for 16-bit+ ADC accuracy |
| 3.8 pF off-capacitance, 7.8 pF on-capacitance | Reduces capacitive loading on driving sources and preserves bandwidth in fast-switching paths |
| 8 kV HBM ESD rating | Eliminates need for external protection diodes in handheld and clinical-grade instrument designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Higher RDS(on) (35 Ω typ.), higher charge injection (2.5 pC), SOIC-8 only | Limited to less demanding industrial meters; lacks MSOP-8 option for space-constrained designs | Select when SOIC-8 footprint is mandatory and 17 Ω on-resistance is not required |
| ADG721BRMZ | Lower supply range (1.8–5.5 V), lower leakage (1 pA typ.), but slower tON (75 ns typ.) | Better for 1.8 V logic systems and ultra-low-leakage pH/ionic sensors; unsuitable for >5 MSPS sampling | Select when interfacing with 1.8 V MCUs or sub-pA leakage is prioritized over speed |
Compared with MAX4617EUA+ and ADG721BRMZ, DG9233EDQ-T1-GE3 uniquely balances 17 Ω on-resistance, 1 pC charge injection, and MSOP-8 packaging - making it optimal for space-constrained, high-accuracy portable instrumentation where both speed and precision are non-negotiable.

FAQ
What is the logic polarity of DG9233EDQ-T1-GE3 control inputs?
The DG9233EDQ-T1-GE3 uses positive logic: a logic-high input (≥2.4 V) turns the corresponding switch ON (closes the NO path), and a logic-low input (≤0.8 V) keeps it OFF. This behavior is confirmed in the truth table for DG9233E on page 2 of Vishay document 75165, and applies identically to DG9233EDQ-T1-GE3 as the MSOP-8 variant of the same silicon die.
Does DG9233EDQ-T1-GE3 support rail-to-rail analog signal switching?
Yes, DG9233EDQ-T1-GE3 supports analog signal voltages from 0 V to V+ (up to +5.5 V), as specified in the "Analog signal range" parameter (0 to V+ V) under both 3 V and 5 V supply conditions in the datasheet. Signals exceeding V+ are clamped by internal diodes, so operation must remain within absolute maximum ratings (−0.3 V to V+ + 0.3 V).
Is DG9233EDQ-T1-GE3 RoHS-compliant and lead-free?
Yes, DG9233EDQ-T1-GE3 is RoHS-compliant and lead-free, as indicated by the "-GE3" suffix in the part number and confirmed in Vishay's ordering information table (page 2, document 75165), which lists it under "lead (Pb)-free" configuration with D suffix (−40 °C to +85 °C).
What is the thermal derating behavior of DG9233EDQ-T1-GE3 above 70 °C?
DG9233EDQ-T1-GE3 requires power dissipation derating above 70 °C at 6.5 mW/°C, as stated in the "Notes" section of the Absolute Maximum Ratings table (page 2, document 75165). For the MSOP-8 package, this means total power must be reduced linearly beyond ambient temperatures of 70 °C to maintain reliability and avoid thermal shutdown.
Can DG9233EDQ-T1-GE3 replace DG9232EDQ-T1-GE3 or DG9234EDQ-T1-GE3 in existing designs?
No - DG9233EDQ-T1-GE3 cannot directly replace DG9232EDQ-T1-GE3 (dual-N.C.) or DG9234EDQ-T1-GE3 (break-before-make) due to fundamental differences in default switch state and timing behavior. Pinout and electrical specs are identical, but logic interpretation and channel interaction differ; PCB-level redesign or firmware rework is required for substitution.
