Product details
Overview
The MAX4622EPE from Maxim Integrated is a precision dual SPDT analog switch with two normally closed (NC) and two normally open (NO) poles, 5Ω max on-resistance, guaranteed 0.5Ω max RON match between channels, and break-before-make operation - designed for low-distortion signal routing in test equipment and communication systems.
For engineers reviewing the MAX4622EPE datasheet, MAX4622EPE pinout, MAX4622EPE application, or MAX4622EPE equivalent, key selection criteria include its ±4.5V to ±18V / +4.5V to +36V supply flexibility, rail-to-rail analog signal handling, <200ns turn-off time, and -40°C to +85°C industrial temperature rating.
Technical Context
The MAX4622EPE implements dual independent SPDT switches with guaranteed break-before-make timing to prevent signal shorting during state transitions. Each switch supports rail-to-rail analog signals from V− to V+, with on-resistance flatness ≤5Ω over the full signal range.
It accepts TTL/CMOS-compatible logic inputs (VINL ≤ 0.8V, VINH ≥ 2.4V) and operates from either bipolar supplies (±4.5V to ±18V) or single positive supplies (+4.5V to +36V), with separate logic supply pin (VL) enabling level-shifting capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 5Ω max - ensures minimal signal attenuation and voltage drop at 10mA load current |
| RON Match | 0.5Ω max - enables precise channel-to-channel signal gain matching in differential or multiplexed paths |
| Turn-Off Time | <200ns - supports high-speed switching in automated test and data-acquisition systems |
| Off-Leakage (85°C) | <5nA - preserves signal integrity in high-impedance sensor or precision measurement circuits |
| Supply Range | ±4.5V to ±18V or +4.5V to +36V - allows direct integration into legacy bipolar and modern single-supply systems |
| Rail-to-Rail Signal | VCOM, VNO, VNC = V− to V+ - eliminates clipping when switching full-range analog waveforms |
| Logic Compatibility | TTL/CMOS - simplifies interface with microcontrollers, FPGAs, and standard logic without level shifters |
Pinout & Package
MAX4622EPE uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch, compatible with standard PCB layouts and socketing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | Digital Logic Input (IN1, IN2) | Active-high control lines determining switch state of each SPDT section |
| 2, 7 | Switch Common Terminal (COM1, COM2) | Analog signal path input/output shared between NC and NO paths per switch |
| 3, 6 | Negative Supply Voltage (V−) | Bipolar negative rail connection; required for dual-supply operation |
| 4, 5, 9, 16 | Normally Open Terminal (NO1–NO4) | Open-circuit by default; connects to COM only when corresponding IN = high |
| 10, 15 | Normally Closed Terminal (NC1, NC2) | Default closed path to COM; disconnects when IN = high (break-before-make) |
| 11 | No Connect (N.C.) | Internally unconnected; must be left floating or tied to GND per layout best practice |
| 12 | Positive Supply Voltage (V+) | Main analog supply rail; supports up to +36V in single-supply mode |
| 13 | Logic Supply (VL) | Independent logic-level reference enabling CMOS/TTL compatibility across supply configurations |
| 14 | GND | Analog ground reference; must be low-impedance and separated from digital ground if noise-sensitive |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed Break-Before-Make | Prevents momentary shorting between NC and NO paths during switching - critical for protecting downstream circuitry |
| 0.5Ω RON Match | Ensures matched gain/attenuation across dual channels in instrumentation or balanced signal paths |
| Rail-to-Rail Analog Handling | Supports full-swing AC/DC signals from V− to V+ without distortion or clipping |
| <5nA Off-Leakage (85°C) | Maintains accuracy in high-Z sensor interfaces and precision integrator applications over full temperature range |
| Pin-Compatible DG403 Replacement | Direct upgrade path for legacy designs using DG403, delivering lower RON, faster switching, and wider supply range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4622CPE | 0°C to +70°C operating range; identical electrical specs and pinout | Suitable only for commercial-temperature applications; not rated for industrial environments | Select MAX4622CPE only if ambient temperature remains within 0°C–70°C and cost sensitivity outweighs thermal margin needs |
| ADG408BRZ | 8-channel single-pole analog switch; 45Ω typical RON; no break-before-make guarantee | Higher channel count but higher on-resistance and no B-B-M timing control | Choose ADG408BRZ only when expanding to 8:1 multiplexing is required and 5Ω RON is not critical |
Compared with MAX4622CPE, the MAX4622EPE adds industrial temperature support without changing footprint or functionality; versus ADG408BRZ, it trades channel count for lower RON, guaranteed B-B-M, and superior leakage performance - making it optimal for dual-path precision routing.

FAQ
What is the maximum supply voltage rating for the MAX4622EPE?
The MAX4622EPE supports bipolar supplies up to ±18V and single positive supplies up to +36V. Absolute maximum ratings specify V+ to GND ≤ +44V and V− to GND ≥ −44V, but sustained operation beyond ±18V or +36V is not recommended. The device maintains guaranteed performance across its specified supply ranges, including RON, leakage, and switching times.
Does the MAX4622EPE require external pull-up or pull-down resistors on its logic inputs?
No, the MAX4622EPE does not require external pull-up or pull-down resistors on IN1 or IN2. Its TTL/CMOS-compatible inputs have defined thresholds (VINL ≤ 0.8V, VINH ≥ 2.4V) and low input current (<0.5µA), allowing direct connection to microcontroller GPIOs or FPGA outputs. However, unused logic inputs should be tied to VL or GND to prevent floating states.
Is break-before-make timing guaranteed for both switch sections in the MAX4622EPE?
Yes, break-before-make operation is guaranteed for both SPDT sections of the MAX4622EPE. The datasheet specifies a maximum break-before-make delay (tD) of 200ns under typical conditions, ensuring that the NC path opens before the NO path closes - preventing transient short circuits in sensitive analog signal paths.
Can the MAX4622EPE switch signals beyond its supply rails?
No, the MAX4622EPE cannot safely switch signals beyond its supply rails. Its analog signal range is strictly limited to V− to V+, as confirmed by absolute maximum ratings and rail-to-rail specification. Applying signals outside this range risks forward-biasing internal protection diodes and exceeding safe current limits, potentially damaging the device or degrading performance.
What is the thermal performance difference between the MAX4622EPE and MAX4622CPE packages?
The MAX4622EPE and MAX4622CPE share identical 16-pin plastic DIP packaging and thermal resistance characteristics. Their primary difference lies in temperature grading: MAX4622EPE is rated for −40°C to +85°C operation, while MAX4622CPE is limited to 0°C to +70°C. Both exhibit the same 842mW maximum power dissipation at +70°C with identical derating slopes (10.53mW/°C above +70°C).
