Product details
Overview
DG442DYZ-T 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 on single (5–34V) or split supplies (±5V to ±22V), enabling use 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 DG442DYZ-T datasheet, DG442DYZ-T pinout, DG442DYZ-T application, or DG442DYZ-T equivalent, this device serves as a drop-in upgrade for DG202-series switches-offering faster switching, lower ON resistance, latch-up immunity, and Pb-free SOIC packaging suitable for reflow assembly.
Technical Context
The DG442DYZ-T implements four independent bilateral SPST analog switches using a high-voltage silicon-gate CMOS process with epitaxial isolation to prevent latch-up. Its logic polarity is inverted relative to DG441: INx = 0V enables conduction (ON), while INx ≥ 2.4V disables (OFF).
It supports rail-to-rail analog signal handling up to ±20V with matched ON-resistance flatness across ±5V input range, and features integrated voltage reference for stable logic thresholds across supply variations from ±5V to ±22V or +5V to +34V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance (max) | 85Ω at +25°C - ensures minimal signal attenuation and gain error in precision gain-setting or multiplexing paths |
| Turn-On Time (max) | 250ns - enables high-speed channel switching in data acquisition and ATE systems |
| Charge Injection (typ) | ±1pC - reduces hold-mode settling error and simplifies anti-aliasing filter design in sample-and-hold stages |
| Analog Signal Range | ±20V - supports full-range bipolar signal routing without external level-shifting circuitry |
| Supply Voltage Range | Single: +5V to +34V; Dual: ±5V to ±22V - accommodates industrial, battery-powered, and legacy instrumentation rails |
| OFF Isolation (typ) | 60dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-channel signal conditioning |
| Input Logic Thresholds | VIL ≤ 0.8V, VIH ≥ 2.4V - ensures robust compatibility with both TTL and CMOS logic families |
Pinout & Package
Package: 16-lead SOIC (Pb-free, RoHS-compliant), body dimensions 9.80 × 3.80 × 1.75 mm (M16.15). Tape-and-reel packaging (DG442DYZ-T) supports automated SMT placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-low logic control inputs - low voltage (≤0.8V) turns corresponding switch ON |
| 2, 7, 10, 15 | D1–D4 | Drain (output) terminals - bidirectional signal path; connected to load or downstream node |
| 3, 6, 11, 14 | S1–S4 | Source (input) terminals - bidirectional signal path; connected to source or upstream node |
| 4 | V− | Negative power supply terminal - sets lower analog rail; must be ≤ −25V relative to GND |
| 5 | GND | Logic common reference - used for digital input referencing and substrate bias |
| 12 | NC | No internal connection - must remain unconnected; no pull-up/down required |
| 13 | V+ | Positive power supply / substrate terminal - sets upper analog rail; must be ≤ +34V relative to GND |
Key Features
| Feature | Design Value |
|---|---|
| Inverted logic control | DG442-specific truth table: low INx = ON state - simplifies interface with active-low enable logic or microcontroller GPIO |
| Bilateral analog switching | Identical rDS(ON) and capacitance performance in either direction - enables flexible signal routing in AC-coupled or bidirectional systems |
| Latch-up immunity | Epitaxial layer prevents SCR triggering - eliminates risk of destructive latch-up under overvoltage or ESD stress |
| Pb-free SOIC packaging | 100% matte tin termination, MSL-3 compliant - supports lead-free reflow soldering and meets RoHS Directive 2011/65/EU |
| Low power consumption | <1.6mW typical quiescent power - extends battery life in portable instrumentation and handheld test gear |

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 offers fault protection and ±36V signal range | Better suited for harsh industrial environments requiring overvoltage survivability | Select when fault tolerance and extended voltage margin outweigh speed/resistance requirements |

FAQ
What is the logic polarity of DG442DYZ-T compared to DG441?
The DG442DYZ-T uses inverted logic control: a logic low (≤0.8V) on INx turns the corresponding switch ON, whereas DG441 requires a logic high (≥2.4V) for ON state. This difference is fundamental to the DG442DYZ-T design and must be accounted for in firmware or logic-level translation. The DG442DYZ-T truth table confirms this behavior across all four channels.
Can DG442DYZ-T operate with a single 12V supply?
Yes, DG442DYZ-T supports single-supply operation from +5V to +34V. At +12V, its analog signal range is 0V to +12V, ON resistance rises to 160Ω max, and tON increases to 450ns max. These values are fully specified in the datasheet's single-supply electrical characteristics table, confirming robust functionality in battery-powered or 12V-rail systems.
Is DG442DYZ-T pin-compatible with DG202-series devices?
Yes, DG442DYZ-T is a drop-in replacement for DG202-series switches, sharing identical 16-pin SOIC pinout, logic interface, and functional block diagram. No PCB changes are required - only verify that supply rails and signal levels fall within DG442DYZ-T's extended specifications (e.g., ±22V dual supply vs. DG202's ±18V limit).
What is the maximum allowable voltage difference between V+ and V− for DG442DYZ-T?
The absolute maximum voltage difference between V+ and V− is 44V. This limit applies regardless of whether operating in single-ended (+34V to GND), symmetrical (±22V), or asymmetrical configurations - provided V+ does not exceed +34V and V− does not go below −25V relative to GND. Exceeding 44V risks permanent damage per Absolute Maximum Ratings.
Does DG442DYZ-T require external charge pump or level-shifter circuitry?
No, DG442DYZ-T integrates an internal voltage reference for logic threshold generation and operates natively across its full supply range (±5V to ±22V or +5V to +34V) without external support components. Its TTL/CMOS-compatible inputs accept standard logic levels directly, eliminating need for level shifters in most microcontroller or FPGA interfaces.
