Product details
Overview
The MAX383CPE+ from Maxim Integrated is a precision single-pole double-throw (SPDT) analog switch with two normally open (NO) and two normally closed (NC) poles, designed for rail-to-rail signal routing in low-voltage systems. It delivers 20Ω typical on-resistance (≤35Ω max), <2Ω matched on-resistance between channels, <5pC charge injection, and <2.5nA off-leakage at +85°C - enabling high-fidelity signal switching in battery-powered test equipment and military radios.
For engineers reviewing the MAX383CPE+ datasheet, MAX383CPE+ pinout, MAX383CPE+ application, or MAX383CPE+ equivalent, key selection criteria include guaranteed on-resistance flatness (<4Ω over full analog range), dual-supply operation (±3V to ±8V), CMOS/TTL logic compatibility, and SPDT break-before-make timing (10–20ns delay).
Technical Context
The MAX383CPE+ implements a monolithic silicon-gate CMOS architecture optimized for low-voltage precision switching. Its internal topology supports true rail-to-rail analog signal handling (VCOM, VNO, VNC = V− to V+) across single (+3V to +15V) or split (±3V to ±8V) supplies while maintaining sub-2Ω channel matching and <4Ω on-resistance variation over the full signal range.
It features guaranteed break-before-make timing (10–20ns), low charge injection (<5pC), and ultra-low leakage (<250pA at +25°C, <2.5nA at +85°C), making it suitable for sample-and-hold circuits and high-impedance audio routing where signal integrity and minimal transient error are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 20Ω typical (≤35Ω max) - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Match | <2Ω between channels - enables accurate differential or ratiometric signal routing without gain mismatch |
| Charge Injection | <5pC - reduces sampling error and settling time in sample-and-hold and data acquisition systems |
| Off-Leakage Current | <2.5nA at +85°C - preserves DC accuracy in high-impedance sensor interfaces and battery-monitoring circuits |
| Switching Speed | tON <175ns, tOFF <100ns - supports fast multiplexing in automated test equipment and communication signal routing |
| Analog Signal Range | Rail-to-rail (V− to V+) - allows full utilization of supply headroom in both single- and dual-supply configurations |
| Logic Compatibility | TTL/CMOS with 3V/5V/±3V/±5V supplies - simplifies interface to microcontrollers, FPGAs, and legacy logic families |
Pinout & Package
MAX383CPE+ uses a 16-pin plastic DIP package (0°C to +70°C operating range), with 0.3-inch body width and standard through-hole footprint. Pin 13 is GND; pins 11 and 14 are V+ and V− respectively; pins 1/3/6/8 are COM terminals; pins 4/5/9/16 are NO/NC terminals; pins 10/15 are logic inputs IN1 and IN2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8 | COM1–COM4 | Common analog terminals - each connects to one NO and one NC path under independent logic control |
| 4, 5, 9, 16 | NO1/NC1, NO2/NC2, NO3/NC3, NO4/NC4 | Normally open/normally closed analog terminals - define SPDT switching states per pole |
| 10, 15 | IN1, IN2 | CMOS/TTL logic inputs - IN1 controls COM1/COM3; IN2 controls COM2/COM4; active-high logic sense |
| 11 | V+ | Positive analog and logic supply - accepts +3V to +15V (single) or ±3V to ±8V (dual) |
| 14 | V− | Negative analog supply - required for dual-supply operation; floats to GND in single-supply mode |
| 13 | GND | Logic ground reference - provides return path for logic inputs and defines 0V reference for digital interface |
| 2, 7, 12 | N.C. | Not internally connected - no electrical function; must remain unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports VCOM/VNO/VNC from V− to V+ - eliminates clipping in wide-dynamic-range audio and sensor front-ends |
| Guaranteed break-before-make timing | 10–20ns delay - prevents momentary short-circuit during state transitions in power-sensitive or fault-tolerant systems |
| Low on-resistance flatness | <4Ω variation over full analog range - maintains consistent gain and linearity across input signal swing |
| Ultra-low charge injection | <5pC - minimizes voltage glitch and settling burden in precision sampling and DAC output buffering |
| Pin-compatible replacement | Direct drop-in for DG403 - enables legacy system upgrades without layout changes or firmware modification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX383EPE | Same die, extended −40°C to +85°C temp range; higher leakage spec (≤2.5nA at +85°C same) | Required for industrial outdoor deployment or automotive cabin environments | Select MAX383EPE when operation beyond 0°C ambient is needed; identical pinout and drive requirements |
| DG403DN | Pin-compatible but higher on-resistance (45Ω typ), no guaranteed break-before-make, no charge injection spec | Suitable only for non-critical AC coupling or low-frequency multiplexing | Choose DG403DN only if cost sensitivity outweighs precision requirements; verify leakage and RON flatness in final design |
Compared with MAX383CPE+, MAX383EPE extends thermal capability without altering electrical behavior, while DG403DN trades precision for legacy compatibility - making MAX383CPE+ optimal for commercial-grade, high-fidelity signal routing where leakage, charge injection, and timing control are design-critical.

FAQ
What is the maximum supply voltage rating for MAX383CPE+?
The MAX383CPE+ supports absolute maximum ratings of V+ = −0.3V to +17V and V− = +0.3V to −17V, with V+ to V− differential up to +17V. For reliable operation, use within recommended ranges: +3V to +15V single supply or ±3V to ±8V dual supply. Exceeding these may cause permanent damage, as confirmed in the Absolute Maximum Ratings table.
Does MAX383CPE+ support rail-to-rail analog signal switching?
Yes, MAX383CPE+ supports rail-to-rail analog signal handling: VCOM, VNO, and VNC can swing from V− to V+ under all specified supply conditions. This is explicitly guaranteed in the Electrical Characteristics tables for both single- and dual-supply modes, enabling full dynamic range utilization in precision signal paths.
What is the guaranteed on-resistance match between channels for MAX383CPE+?
The MAX383CPE+ guarantees on-resistance match (∆RON) of less than 2Ω between any two channels, measured under specified voltage and temperature conditions. This parameter is 100% tested and documented in the Dual Supplies Electrical Characteristics table, ensuring predictable channel tracking in differential or multi-path routing.
Is MAX383CPE+ pin-compatible with industry-standard analog switches?
Yes, MAX383CPE+ is pin-compatible with the DG403 series, including DG403DN. The pin configuration, terminal functions, and package outline match exactly - allowing direct replacement in existing layouts without PCB revision, as stated in the Features section and verified in the Pin Description table.
What is the break-before-make timing specification for MAX383CPE+?
The MAX383CPE+ guarantees a break-before-make time delay (tD) of 10ns minimum to 20ns maximum, applicable only to its SPDT configuration. This parameter is tested and specified in the Dual Supplies Electrical Characteristics table and ensures safe channel isolation during logic-controlled transitions.
