Product details
Overview
DG442DVZ from Intersil is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 85Ω max ON resistance, 250ns max tON, and ±20V analog signal range. It operates from single (5–34V) or split (±5V to ±22V) supplies and is used in precision sample-and-hold circuits, audio routing, and automated test equipment where low charge injection (±1pC) and high OFF isolation (60dB) are critical.
For engineers reviewing the DG442DVZ datasheet, DG442DVZ pinout, DG442DVZ application, or DG442DVZ equivalent, this page delivers verified specifications, TSSOP-16 package details, logic polarity distinction vs. DG441, real-world switching performance under dual/supply conditions, and validated alternatives for signal-path redesign.
Technical Context
The DG442DVZ implements four independent bilateral SPST switches using a high-voltage silicon-gate CMOS process with epitaxial latch-up protection. Its logic polarity is inverted relative to DG441: INx = 0V enables the switch (ON), while INx = 2.4V disables it (OFF).
It supports rail-to-rail analog signals up to ±20V with matched ON-resistance flatness across ±5V input range, and features low leakage (<0.5nA at +25°C) and minimal capacitive feedthrough (CS(OFF)/CD(OFF) = 4pF each).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (max) | 85Ω at +25°C, V± = ±15V - ensures <0.1% gain error in 10kΩ precision resistor networks |
| Turn-On Time (max) | 250ns with RL = 1kΩ, CL = 35pF - supports >1MHz multiplexed data acquisition |
| Analog Signal Range | ±20V (dual supply) or 0–12V (single supply) - accommodates industrial sensor outputs and audio line-level signals |
| Charge Injection | ±1pC - enables sub-12-bit accuracy in sample-and-hold without external correction |
| OFF Isolation | 60dB at 1MHz - suppresses crosstalk between adjacent channels in multi-channel ATE systems |
| Supply Voltage Range | V+ to V− ≤ 44V; V+ ≤ +34V, V− ≥ −25V - allows flexible biasing for ±15V op-amp interfaces |
| Logic Thresholds | VIL ≤ 0.8V, VIH ≥ 2.4V - ensures robust noise margin with 3.3V/5V microcontroller GPIO |
Pinout & Package
Package: 16-lead TSSOP (Moisture Sensitivity Level 1, Pb-free, RoHS compliant, JEDEC MO-153-AB compliant, body size 4.9mm × 3.9mm × 1.05mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-low logic control inputs: 0V = switch ON, 2.4V = switch OFF (DG442-specific inversion) |
| 2, 15, 10, 7 | D1–D4 | Drain (output) terminals - bidirectional, symmetric with source pins for AC-coupled signals |
| 3, 14, 11, 6 | S1–S4 | Source (input) terminals - electrically identical to drains; interchangeable in layout |
| 4 | V− | Negative supply rail - must be connected even in single-supply operation (0V reference) |
| 5 | GND | Logic common ground - separate from analog signal return; requires star grounding for low-noise apps |
| 12 | NC | No internal connection - must remain unconnected; no pull-up/down required |
| 13 | V+ | Positive supply and substrate tie - connects to die substrate; must be at highest potential in system |
Key Features

| 44V max supply differential | Supports wide dynamic range analog front-ends, including ±22V op-amp rails and 40VP-P signal switching |
| Pb-free TSSOP package | RoHS-compliant, MSL-1 reflow compatible, footprint matches industry-standard 16-pin TSSOP layouts (M16.173) |
Applications
| Audio Switching | Sample and Hold Circuits |
|---|---|
Use Scenario: Routing line-level stereo signals between multiple DAC outputs and amplifier inputs in pro-audio mixers. IC Role / Device Role / Timing Role: Quad SPST analog switch providing channel-selectable signal path with <4pF OFF capacitance to preserve high-frequency bandwidth. Use Value: 60dB OFF isolation prevents audible crosstalk between left/right channels at 20kHz; low rDS(ON) variation avoids level mismatch across volume settings. |

IC Role / Device Role / Timing Role: Precision switch isolating hold capacitor during acquisition phase, controlled by FPGA timing engine with <250ns edge alignment. Use Value: ±1pC charge injection limits hold-step error to <1LSB in 16-bit systems; matched ON resistance ensures consistent settling across all four channels. |
| Data Acquisition Systems | Automatic Test Equipment |

IC Role / Device Role / Timing Role: One DG442DVZ per 4-channel group, providing low-leakage (<0.5nA) analog switching with rail-to-rail ±10V support. Use Value: Sub-nA OFF leakage prevents thermocouple cold-junction drift; 85Ω rDS(ON) tolerance maintains calibration integrity over temperature. |
Use Scenario: Configurable signal routing matrix in boundary-scan test platforms switching between DUT pins, reference sources, and measurement instruments. IC Role / Device Role / Timing Role: Reconfigurable analog path element enabling programmable stimulus/response paths with <210ns tOFF for rapid test sequencing. Use Value: 100dB crosstalk suppression prevents false fault detection during parallel pin testing; 44V supply range accommodates mixed-voltage DUTs. |
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 |
|---|---|---|---|
| MAX4618ESE+ | Higher ON resistance (100Ω typ), slower tON (300ns), but lower charge injection (0.5pC); requires dual supply only | Better suited for ultra-low-distortion audio where charge injection dominates, less ideal for high-speed DAQ | Select MAX4618ESE+ when sub-0.5pC injection is mandatory and speed <3MHz is acceptable |
| ADG1412BRUZ | Lower rDS(ON) (1.8Ω typ), higher supply voltage limit (+36V/−20V), but larger SOIC-16 package and higher cost | Preferred for high-current analog muxing (e.g., 100mA sensor excitation) where ON-resistance loss must be minimized | Choose ADG1412BRUZ when <2Ω ON resistance is required and board space allows SOIC footprint |
Compared with MAX4618ESE+ and ADG1412BRUZ, DG442DVZ offers the optimal balance of speed (250ns), precision (±1pC), and supply flexibility (single/dual) in the smallest TSSOP-16 package-making it ideal for space-constrained, medium-speed instrumentation where cost and layout density matter.

FAQ
What is the logic polarity difference between DG442DVZ and DG441DVZ?
The DG442DVZ uses active-low logic control: applying 0V to INx turns the corresponding switch ON, while 2.4V turns it OFF. In contrast, DG441DVZ uses active-high logic (2.4V = ON). This inversion is hardwired in the die design and cannot be changed externally. Both share identical analog performance, pinout, and package - only the logic sense differs. Always verify control signal polarity before substituting DG442DVZ in a DG441-based design.
Can DG442DVZ operate from a single 5V supply?
Yes, DG442DVZ supports single-supply operation from +5V to +34V. At V+ = 5V and V− = 0V, its analog signal range is 0–5V, rDS(ON) rises to ≤200Ω (max), and tON extends to 450ns (max). Input thresholds remain valid (VIL ≤ 0.8V, VIH ≥ 2.4V), ensuring compatibility with standard 5V TTL/CMOS logic. For best performance, use V+ ≥ 12V in single-supply mode.
What is the maximum allowable analog signal voltage when using ±15V supplies?
With V+ = +15V and V− = −15V, DG442DVZ supports analog signals from −15V to +15V (±15V), as confirmed by the Electrical Specifications table on page 4 of FN3281 Rev 10.00. The absolute maximum rating is ±20V, but guaranteed performance (e.g., rDS(ON), leakage) is specified only up to ±15V under those supply conditions. Exceeding ±15V may increase distortion or leakage without violating absolute ratings.
Is the NC pin (Pin 12) required to be grounded or left floating?
Pin 12 (NC) has no internal connection and must be left unconnected - neither grounded nor tied to any voltage. Connecting it may cause unpredictable behavior or damage. The datasheet explicitly states "No Internal Connection" in the Pin Descriptions table (page 3), and the die layout diagram confirms no bond wire or circuit node is attached to this pad. PCB layout should omit any trace or copper pour at Pin 12.
How does DG442DVZ handle bidirectional analog signals?
DG442DVZ is fully bilateral: its S and D terminals are functionally identical, with matched rDS(ON), capacitance, and leakage in either direction. This allows seamless AC coupling, audio signal routing, or current-sense path reversal without performance penalty. The schematic diagram (page 3) shows symmetrical S/D structure, and the Applications section explicitly cites "bidirectional signals" as a key capability - confirming that signal flow direction imposes no design constraints on DG442DVZ.
