Product details
Overview
The MAX383BEPE 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-operated and military-grade equipment.
For engineers reviewing the MAX383BEPE datasheet, MAX383BEPE pinout, MAX383BEPE application, or MAX383BEPE equivalent, this device supports dual-supply (±3V to ±8V) and single-supply (+3V to +15V) operation, maintains CMOS/TTL logic compatibility across 3V/5V/±3V/±5V inputs, and provides break-before-make timing (10–20ns) critical for glitch-free audio and test instrumentation signal paths.
Technical Context
The MAX383BEPE implements a monolithic silicon-gate CMOS architecture optimized for low-voltage precision switching. Its internal design guarantees flat on-resistance (<4Ω variation) over the full analog signal range (V− to V+), tightly matched channel resistance (<2Ω delta), and ultra-low charge injection (<5pC) - all essential for sample-and-hold accuracy and minimal signal distortion in DC-coupled paths.
It features integrated protection diodes on all analog terminals (COM, NO, NC), supports rail-to-rail analog signal handling, and retains fast switching performance (tON < 175ns, tOFF < 100ns) across its full operating temperature range (−40°C to +85°C) without requiring external level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 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 - prevents voltage glitches in sample-and-hold and multiplexed ADC front-ends |
| Off-leakage current | <2.5nA at +85°C - preserves signal integrity in high-impedance sensor and battery-monitoring circuits |
| Supply range | +3V to +15V single or ±3V to ±8V dual - supports wide input voltage flexibility without external regulators |
| Switching speed | tON < 175ns, tOFF < 100ns - suitable for high-speed test equipment and real-time communication signal routing |
| Logic compatibility | TTL/CMOS with 3V/5V/±3V/±5V supplies - eliminates need for level translators in mixed-voltage systems |
Pinout & Package
MAX383BEPE is housed in a 16-pin plastic DIP package (0.300" width), rated for −40°C to +85°C operation. Pin assignments are validated per Maxim's official pin configuration diagram and electrical specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8 | COM₁, COM₂, COM₃, COM₄ | Common analog terminals - each pairs with corresponding NO/NC for independent SPDT switching |
| 4, 5, 9, 16 | NO₁, NO₂, NO₃, NO₄ | Normally open analog outputs - conduct only when associated IN logic input is high |
| - | NC₁, NC₂, NC₃, NC₄ | Normally closed analog outputs - conduct only when associated IN logic input is low (MAX383-specific) |
| 10, 15 | IN₁, IN₂ | CMOS/TTL logic inputs - IN₁ controls COM₁/COM₃; IN₂ controls COM₂/COM₄ |
| 11 | V+ | Positive supply rail - powers analog and logic sections; accepts +3V to +15V or +5.5V max in dual-supply mode |
| 14 | V− | Negative supply rail - required for bipolar operation (±3V to ±8V); tied to GND for single-supply use |
| 13 | GND | Logic ground reference - decouples digital noise from analog signal paths |
| 2, 7, 12 | N.C. | No internal connection - must be left unconnected per datasheet; no pull-up/down or routing required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ - enables full dynamic range utilization in ±5V and +12V systems without clipping |
| Break-before-make timing | 10–20ns guaranteed delay - prevents momentary short-circuit during pole transition in audio and power control applications |
| Guaranteed on-resistance flatness | <4Ω variation over full analog range - ensures consistent gain and linearity across input voltage swing |
| Low power consumption | <10µW quiescent - extends battery life in portable test gear and handheld military radios |
| Pin-compatible replacement | Direct drop-in for DG403 - simplifies legacy system upgrades without PCB redesign |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX383CPE | Same die, 0°C to +70°C temp grade - lower max operating temperature and no extended reliability screening | Suitable for commercial-grade instrumentation but not industrial/military environments | Select MAX383CPE only for cost-sensitive non-extended-temp applications where −40°C startup is not required |
| DG403DN | Pin-compatible SPDT switch; higher RON (45Ω typ), higher leakage (5nA @ +85°C), no guaranteed break-before-make | Lacks precision specs needed for sample-and-hold or low-leakage sensor interfaces | Use DG403DN only in non-critical general-purpose routing where matching and leakage are not design constraints |
Compared with MAX383CPE and DG403DN, the MAX383BEPE uniquely combines −40°C to +85°C operation, <2Ω channel matching, and guaranteed break-before-make timing - making it the only option qualified for ruggedized test equipment and military radio signal conditioning where parametric consistency is mandatory.

FAQ
What is the maximum analog signal voltage range supported by the MAX383BEPE?
The MAX383BEPE supports analog signals from V− to V+, enabling rail-to-rail operation. With ±5V dual supplies, it handles −5V to +5V; with +12V single supply, it routes 0V to +12V. Absolute maximum ratings limit V+ to +17V and V− to −17V, but sustained operation must stay within specified supply ranges (±3V to ±8V or +3V to +15V) to ensure guaranteed performance and reliability of the MAX383BEPE.
Does the MAX383BEPE require external protection diodes for overvoltage conditions?
No - the MAX383BEPE integrates internal protection diodes on all analog terminals (COM, NO, NC), as confirmed in the "Overvoltage Protection" section of the datasheet. These diodes clamp signals exceeding V+ or V−, provided forward current remains below 30mA continuous. External diodes are only recommended if absolute maximum ratings risk being exceeded during power sequencing - a scenario not required for standard MAX383BEPE operation.
Is the MAX383BEPE pin-compatible with the DG403, and what are the key functional differences?
Yes, the MAX383BEPE is pin-compatible with the DG403 and serves as a direct upgrade. Key differences include lower on-resistance (20Ω vs. 45Ω typ), tighter channel matching (<2Ω vs. unspecified), guaranteed break-before-make timing (10–20ns), and lower charge injection (<5pC vs. ~10pC). These improvements make the MAX383BEPE suitable for higher-precision applications where the DG403's looser specs would degrade signal fidelity.
What is the guaranteed on-resistance flatness specification for the MAX383BEPE, and why does it matter?
The MAX383BEPE guarantees on-resistance flatness of ≤4Ω over its full analog signal range (V− to V+), meaning the variation between minimum and maximum RON across the entire voltage swing is bounded. This matters because flat RON prevents gain nonlinearity in variable-gain amplifiers, preserves amplitude accuracy in multiplexed sensor arrays, and avoids distortion in audio signal paths - all critical in precision measurement and communication systems using the MAX383BEPE.
Can the MAX383BEPE operate from a +3.3V single supply, and what performance trade-offs occur?
Yes, the MAX383BEPE operates from +3.3V (3.0V to 3.6V) single supply, with verified specs including RON = 75Ω (typ), tON = 250ns (max), and leakage < 0.2nA at +25°C. Trade-offs versus +5V operation include higher on-resistance (reducing drive capability), slower switching (affecting high-frequency multiplexing), and reduced analog signal headroom (0V to +3.3V). These are acceptable in low-power portable devices where the MAX383BEPE's ultra-low leakage and rail-to-rail support remain advantageous.
