Product details
Overview
DG212DY+ from Maxim Integrated is a quad SPST normally open CMOS analog switch rated for ±4.5V to ±18V dual-supply operation, featuring 175Ω typical RDS(ON), <5nA OFF-leakage, and guaranteed break-before-make switching. It serves as a signal routing element in precision analog front-ends, supporting bidirectional current flow without signal offset in programmable gain amplifiers and automatic test equipment.
For engineers reviewing the DG212DY+ datasheet, DG212DY+ pinout, DG212DY+ application, or DG212DY+ equivalent, key selection criteria include its -40°C to +85°C operating range, SO-16 package, absence of VL logic supply requirement, and compatibility with TTL/CMOS control logic under wide analog signal swing conditions.
Technical Context
The DG212DY+ implements four independent SPST switches using monolithic CMOS process technology, with inverted logic inputs relative to DG201/DG211. Each switch guarantees break-before-make timing to prevent momentary shorting during state transitions.
It operates without a separate VL logic supply-unlike legacy equivalents-while maintaining full compatibility with ±15V analog rails and TTL/CMOS input thresholds. The device remains nonlatching even when power supplies are disconnected while analog signals remain present at S/D terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail signal switching across industrial and test equipment voltage ranges |
| RDS(ON) | 175Ω max - ensures low insertion loss and minimal gain error in precision amplifier paths |
| OFF-Leakage Current | ±5nA max - preserves accuracy in high-impedance sample/hold and sensor interface circuits |
| Switching Time (tON/tOFF) | 460ns / 450ns - enables reliable multiplexing at >1MHz update rates in ATE systems |
| Power Supply Range | ±4.5V to ±18V - allows flexible biasing in mixed-signal systems with varying rail constraints |
| Logic Compatibility | CMOS/TTL - eliminates level-shifting needs when interfacing with microcontrollers or FPGAs |
| OFF-Isolation | 70dB - suppresses crosstalk between channels in multi-channel analog routing applications |
Pinout & Package
Package: 16-pin SOIC (SO), JEDEC MS-012 compliant, body width 3.9mm, lead pitch 1.27mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Inverted logic control inputs - low = switch ON, compatible with standard digital drivers |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - bidirectional analog node connection points, no polarity restriction |
| 3, 6, 11, 14 | S1–S4 | Source terminals - bidirectional analog node connection points, symmetric with D pins |
| 4 | V− | Negative supply rail - must be connected to system −VSS; internal substrate reference |
| 5 | GND | Digital ground reference - separate from analog return but tied to system common |
| 12 | N.C. | No internal connection - left unconnected per design; not usable as thermal pad or auxiliary terminal |
| 13 | V+ | Positive supply rail - connected to internal substrate; requires stable +VDD source |
Key Features
| Feature | Design Value |
|---|---|
| No VL logic supply required | Eliminates third power rail dependency, simplifying PCB layout and reducing BOM count versus legacy DG212 variants |
| Guaranteed break-before-make | Prevents transient short-circuits during channel switching-critical for fault-tolerant analog multiplexers |
| Nonlatching behavior | Remains functional after power-down with live analog inputs-enables hot-swap and safe power sequencing |
| Constant RDS(ON) over signal range | Minimizes THD and gain variation across ±15V analog swing-essential for audio and instrumentation |
| Bidirectional conduction | Supports signal routing in either direction without polarity constraints-ideal for differential and AC-coupled paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single SPST, 4.5Ω RDS(ON), +3V to +36V single-supply only | Limited to unipolar rail systems; lacks ±15V analog swing capability | Select when low on-resistance and single-supply operation outweigh need for bipolar signal handling |
| ADG1412BRUZ | Quad SPST, 1.8Ω RDS(ON), ±15V rating, but requires VL supply and has higher leakage (±20nA) | Higher precision routing possible, but VL dependency increases layout complexity | Choose for ultra-low RDS(ON) where leakage and supply count are secondary concerns |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG212DY+ uniquely balances wide bipolar supply support, no-VL simplicity, and sub-5nA leakage-making it optimal for industrial ATE and programmable analog signal conditioning where reliability and rail flexibility are prioritized over minimum on-resistance.

FAQ
What is the operating temperature range for DG212DY+?
The DG212DY+ is specified for −40°C to +85°C operation, matching the DG212D/E grade. This extended industrial temperature range ensures reliable performance in automated test equipment, industrial PLCs, and outdoor communications hardware where ambient conditions vary significantly. The SO-16 package maintains thermal stability across this full range without derating penalties beyond datasheet limits.
Does DG212DY+ require a VL logic supply voltage?
No, DG212DY+ does not require a VL logic supply. Unlike earlier DG212 variants from other manufacturers, Maxim's implementation integrates logic-level translation internally, allowing direct TTL/CMOS control from 0V/3.3V/5V logic while operating from ±4.5V to ±18V analog supplies. This eliminates an external rail and associated decoupling, simplifying power architecture in portable and space-constrained designs.
What is the maximum analog signal voltage supported by DG212DY+?
The DG212DY+ supports analog signals from V− to V+, with absolute maximum ratings allowing ±15V operation under standard conditions. Its analog signal range is specified as ±15V, meaning it reliably passes signals spanning the full rail-to-rail difference when powered from ±15V supplies. Exceeding ±15V risks violating the ±18V continuous supply limit and may trigger internal clamping or damage.
How does DG212DY+ handle power-down with live analog inputs?
DG212DY+ is explicitly designed to remain nonlatching when power supplies are removed while analog signals remain present at S or D terminals. This behavior is guaranteed per Maxim's datasheet and enables safe hot-swap operation and graceful degradation in systems where analog sensors stay active during controller reset or power cycling. No external protection diodes are required for basic fault tolerance.
Is DG212DY+ pin-compatible with DG202DY+?
No, DG212DY+ is not pin-compatible with DG202DY+. Although both are quad SPST analog switches in SO-16 packages, DG212DY+ uses inverted logic inputs (low = ON), whereas DG202DY+ uses non-inverted logic (high = ON). Their pin functions differ at IN1–IN4: identical pin numbers carry opposite logic polarity, making direct substitution impossible without board-level logic inversion or firmware modification.
