Product details
Overview
DG442DVZ-T from Intersil is a monolithic quad SPST CMOS analog switch with TTL/CMOS-compatible digital inputs, 85Ω max ON resistance, <250ns turn-on time, ±20V analog signal range, and operation on single (5–34V) or split (±5V to ±22V) supplies - used in precision sample-and-hold circuits, audio routing, and automated test equipment.
For engineers reviewing the DG442DVZ-T datasheet, DG442DVZ-T pinout, DG442DVZ-T application, or DG442DVZ-T equivalent, this page delivers verified electrical specs, TSSOP-16 terminal mapping, logic polarity distinction vs DG441, and two validated drop-in alternatives for analog switching design validation.
Technical Context
The DG442DVZ-T implements four independent bilateral SPST switches fabricated in a high-voltage silicon-gate CMOS process with epitaxial isolation to prevent latch-up. Its logic control is inverted relative to DG441: INx = 0V closes the switch (ON), while INx ≥2.4V opens it (OFF).
It supports rail-to-rail analog signals up to ±20V with low charge injection (±1pC typ), low OFF capacitance (4pF), and high OFF isolation (60dB at 1MHz). Supply voltage range is limited by V+–V− ≤44V, with V+ ≤+34V and V− ≥–25V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (max) | 85Ω at +25°C, ±15V supplies - ensures minimal signal attenuation and gain error in precision resistor networks. |
| Turn-On Time (max) | 250ns at RL=1kΩ, CL=35pF - enables fast channel selection in multiplexed data acquisition systems. |
| Analog Signal Range | ±20V (max) - supports full-swing AC-coupled audio and industrial sensor signals without clipping. |
| Charge Injection | ±1pC (typ) - reduces hold-step error and settling time in sample-and-hold amplifiers. |
| Supply Voltage Range | V+ to V− ≤44V; V+ ≤+34V, V− ≥–25V - allows flexible single-ended (5–34V) or symmetrical (±5V to ±22V) biasing. |
| Logic Thresholds | VIH ≥2.4V, VIL ≤0.8V - ensures robust interfacing with 3.3V/5V microcontrollers and FPGA I/O banks. |
| OFF Isolation | 60dB at 1MHz - suppresses crosstalk between inactive channels in multi-channel instrumentation. |
Pinout & Package
Package: 16-lead TSSOP (Pb-free, RoHS-compliant), 4.9mm × 3.9mm footprint, 0.65mm pitch, 1.1mm max height - optimized for space-constrained PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; logic LOW (≤0.8V) turns corresponding switch ON (DG442-specific inverted logic). |
| 2, 7, 10, 15 | D1–D4 | Drain (output) terminals - bidirectional; connect to load or downstream signal path. |
| 3, 6, 11, 14 | S1–S4 | Source (input) terminals - bidirectional; connect to source signal or sensor output. |
| 4 | V− | Negative power supply rail - must be ≤–25V referenced to GND; sets lower analog voltage limit. |
| 5 | GND | Logic ground reference - common return for digital inputs and substrate bias; not analog ground. |
| 12 | NC | No internal connection - must remain unconnected; no pull-up/down or routing required. |
| 13 | V+ | Positive power supply / substrate terminal - must be ≤+34V referenced to GND; sets upper analog limit. |
Key Features
| Feature | Design Value |
|---|---|
| Inverted logic control | DG442-specific: low-level enable simplifies direct interface with active-low microcontroller GPIO or FPGA outputs. |
| Bilateral analog switching | Identical rDS(ON) and leakage performance in either direction - supports AC-coupled audio and bidirectional bus isolation. |
| Low charge injection (±1pC) | Minimizes voltage step on hold capacitors - critical for <12-bit accuracy in sample-and-hold and ADC front-end designs. |
| Pb-free TSSOP package | RoHS-compliant, MSL-1 rated, compatible with SnPb and Pb-free reflow profiles - meets industrial and medical manufacturing requirements. |
| 44V max supply differential | Enables use with ±15V op-amps, ±12V DACs, and 24V industrial I/O - avoids need for level-shifting or auxiliary supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single-supply only (2.7–12V); 60Ω max rDS(ON); 100ns tON; no dual-supply support. | Not suitable for ±15V op-amp interfaces or rail-to-rail AC signals beyond 12Vpp. | Select when cost-sensitive, low-voltage, single-rail systems dominate and dual-supply operation is unnecessary. |
| ADG1412BRUZ | 44V max supply; 1.8Ω max rDS(ON); 125ns tON; CMOS-compatible but non-inverted logic (like DG441). | Requires logic inversion for drop-in replacement; superior ON resistance but higher quiescent current (250µA vs 15µA). | Choose for ultra-low distortion audio or high-precision instrumentation where ON resistance and speed outweigh logic compatibility. |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG442DVZ-T uniquely balances wide supply flexibility (±22V), inverted logic for direct MCU control, and ultra-low leakage (<0.5nA at +25°C), making it optimal for mixed-signal industrial and test systems requiring reliability over raw speed.

FAQ
What is the logic polarity of DG442DVZ-T compared to DG441?
The DG442DVZ-T uses inverted logic: a logic LOW (≤0.8V) on INx turns the corresponding switch ON, whereas DG441 requires a HIGH (≥2.4V) to activate. This difference is hardwired and cannot be configured. The DG442DVZ-T datasheet truth table explicitly confirms ON state at VIN ≤0.8V, making it ideal for direct connection to active-low microcontroller outputs without external inverters.
Can DG442DVZ-T operate from a single 5V supply?
Yes, DG442DVZ-T supports single-supply operation from +5V to +34V with V− tied to ground. At +5V, its analog signal range is 0V to +5V (full-scale), rDS(ON) is ≤200Ω (max), and tON is ≤450ns. These values are specified in the "Electrical Specifications (Single Supply)" section of the FN3281 datasheet, confirming functional operation - though performance (e.g., ON resistance, speed) improves with higher supply voltages.
What is the maximum analog signal voltage supported by DG442DVZ-T?
The DG442DVZ-T supports analog signals from V− to V+, with a maximum differential of ±20V (i.e., 40VPP) under standard conditions. This is confirmed in the "Operating Conditions" table (Page 4) and Figure 8–11 of the FN3281 datasheet. Exceeding ±20V risks exceeding absolute maximum ratings and may cause increased leakage or permanent damage.
Does DG442DVZ-T require external pull-up or pull-down resistors on its INx pins?
No, DG442DVZ-T has TTL/CMOS-compatible inputs with guaranteed switching thresholds (VIH ≥2.4V, VIL ≤0.8V) and sub-microamp input current (±0.5µA max). It drives directly from microcontroller GPIO, FPGA outputs, or logic gates without external biasing. The "Digital Input Characteristics" table (Page 4) specifies IIL and IIH ≤±0.5µA across temperature, eliminating need for pull resistors in standard interfacing.
Is DG442DVZ-T pin-compatible with DG442DY-T or DG442DJZ?
Yes - DG442DVZ-T shares identical pinout and electrical specifications with DG442DY-T (SOIC-16) and DG442DJZ (PDIP-16), differing only in package type (TSSOP vs SOIC vs PDIP) and RoHS compliance. All three use the same 16-pin layout shown in the "Pin Descriptions" table (Page 3) and "Pinout" diagram (Page 1), enabling direct PCB footprint substitution when thermal and space constraints allow.
