Product details
Overview
The MAX383CSE+ from Maxim Integrated is a precision single-pole double-throw (SPDT) analog switch with two normally open (NO) and two normally closed (NC) poles, operating from ±3V to ±8V dual supplies or +3V to +15V single supply. It delivers 20Ω typical on-resistance (35Ω max), <2Ω matched RON between channels, <5pC charge injection, and <2.5nA off-leakage at +85°C - enabling high-fidelity signal routing in battery-powered test equipment and military radios.
For engineers reviewing the MAX383CSE+ datasheet, MAX383CSE+ pinout, MAX383CSE+ application, or MAX383CSE+ equivalent, this page provides verified electrical specifications, truth-table-validated SPDT switching behavior, rail-to-rail analog signal handling up to ±4.5V, CMOS/TTL-compatible logic inputs, and confirmed pin compatibility with DG403 for drop-in replacement evaluation.
Technical Context
The MAX383CSE+ implements a monolithic silicon-gate CMOS architecture optimized for low-voltage precision switching. Its break-before-make timing (10–20ns) prevents signal shorting during pole transition, while guaranteed flat on-resistance (<4Ω variation over full analog range) ensures minimal gain error in instrumentation front-ends.
Charge injection (<5pC) and off-isolation (72dB at 1MHz) are design-guaranteed parameters critical for sample-and-hold accuracy and crosstalk-sensitive audio routing. The device maintains rail-to-rail analog signal capability across its full ±3V to ±8V dual-supply or +3V to +15V single-supply operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 20Ω typical (35Ω max) - enables low insertion loss in signal paths up to ±4.5V analog swing |
| On-resistance match | <2Ω between channels - ensures matched gain/attenuation in differential or multiplexed sensor interfaces |
| Charge injection | <5pC - minimizes voltage glitch in sample-and-hold circuits and ADC input buffers |
| Off-leakage current | <2.5nA at +85°C - preserves DC accuracy in high-impedance sensor conditioning stages |
| Switching speed | 175ns turn-on / 100ns turn-off - supports >1MHz multiplexing in automated test equipment |
| Analog signal range | V− to V+ - allows rail-to-rail signal handling without level-shifting in ±5V systems |

Pinout & Package
MAX383CSE+ is housed in a 16-pin narrow SO (small-outline) package with 0.300-inch body width, RoHS-compliant lead finish, and operating temperature range of 0°C to +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8 | COM₁–COM₄ | Common analog terminals - each connects to one NO/NC pair; COM₁/COM₃ controlled by IN₁, COM₂/COM₄ by IN₂ |
| 4, 5, 9, 16 | NO₁–NO₄ | Normally open analog outputs - conduct to respective COM when corresponding IN = high |
| - | NC₁–NC₄ | Normally closed analog outputs - conduct to respective COM when corresponding IN = low |
| 10, 15 | IN₁, IN₂ | Digital control inputs - active-high logic controls two independent SPDT switches per input |
| 11 | V+ | Positive analog/logic supply - accepts +3V to +15V (single) or ±3V to ±8V (dual) |
| 14 | V− | Negative analog supply - required for dual-supply operation; tied to GND for single-supply use |
| 13 | GND | Logic ground reference - establishes 0V reference for TTL/CMOS input thresholds |
| 2, 7, 12 | N.C. | No internal connection - must be left unconnected; no pull-up/down or bypass required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - eliminates need for external level shifters in ±5V systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX383ESE | Same die, -40°C to +85°C extended temperature grade; identical pinout and specs | Required for industrial outdoor test gear or avionics where ambient exceeds +70°C | Select MAX383ESE when operating temperature must exceed +70°C; otherwise MAX383CSE+ suffices for commercial-grade equipment. |
| ADG403BRZ | SPDT switch with 35Ω max RON, but higher 10pC charge injection and no guaranteed RON match | Suitable for non-critical audio routing but not precision sample-and-hold or metrology | Choose ADG403BRZ only if cost is primary constraint and <2Ω RON match or <5pC injection are not required. |
Compared with MAX383ESE, the MAX383CSE+ offers identical functionality at lower cost for 0°C to +70°C environments; versus ADG403BRZ, it delivers superior precision (half the charge injection, guaranteed matching) essential for measurement-grade signal paths.

FAQ
What is the maximum analog signal voltage range supported by the MAX383CSE+?
The MAX383CSE+ supports analog signals from V− to V+, enabling rail-to-rail operation. With ±5V dual supplies, it handles ±4.5V signals; with +5V single supply (V− = GND), it supports 0V to +4.5V. Absolute maximum ratings allow V+ to +17V and V− to −17V, but functional analog range remains bounded by supply rails. This capability is explicitly confirmed in the Electrical Characteristics tables for both dual- and single-supply configurations in the MAX383CSE+ datasheet.
Does the MAX383CSE+ require external protection diodes for overvoltage conditions?
No, the MAX383CSE+ includes internal protection diodes on all analog pins (COM, NO, NC, IN), clamping signals to V+ and V−. External diodes are only recommended if power-supply sequencing cannot be controlled - for example, when V+ and V− may be applied after logic inputs. Adding external diodes reduces the usable analog range by ~0.7V but preserves low RON and leakage performance. This guidance is detailed in the Applications Information section of the MAX383CSE+ datasheet.
How many independent switching channels does the MAX383CSE+ provide?
The MAX383CSE+ integrates two independent single-pole double-throw (SPDT) switches. Each SPDT consists of one common (COM) terminal, one normally open (NO), and one normally closed (NC) terminal. IN₁ controls COM₁/NO₁/NC₁ and COM₃/NO₃/NC₃; IN₂ controls COM₂/NO₂/NC₂ and COM₄/NO₄/NC₄. Thus, it provides four fully isolated analog paths with break-before-make timing, as shown in the Truth Tables and Pin Description sections of the MAX383CSE+ documentation.
Is the MAX383CSE+ pin-compatible with the DG403 analog switch?
Yes, the MAX383CSE+ is explicitly pin-compatible with the DG403, as stated in the Features section of its datasheet. Both devices share identical 16-pin SO packaging, pin assignments (including COM/NO/NC/IN/V+/V−/GND locations), and logic polarity. This allows direct replacement in existing DG403-based designs without PCB modification, provided supply voltages and signal ranges fall within MAX383CSE+ specifications - a key advantage for legacy system upgrades.
What is the guaranteed on-resistance flatness specification for the MAX383CSE+?
The MAX383CSE+ guarantees on-resistance flatness of ≤4Ω maximum variation across its specified analog signal range (V− to V+). This parameter - defined as the difference between maximum and minimum RON measured over the full voltage range - is tested and guaranteed for all temperature grades. It ensures minimal distortion and gain error in precision applications like sample-and-hold circuits and instrumentation amplifiers, as documented in the Electrical Characteristics table under "On-Resistance Flatness" for both dual- and single-supply conditions.
