Product details
Overview
The MAX301CPE+ from Maxim Integrated is a precision dual SPST analog switch in 16-pin plastic DIP packaging, operating from ±4.5V to ±20V bipolar or +10V to +30V single supply, delivering <35Ω on-resistance, <2Ω channel-to-channel match, and <15pC charge injection for high-accuracy signal routing in test equipment and military radios.
For engineers reviewing the MAX301CPE+ datasheet, MAX301CPE+ pinout, MAX301CPE+ application, or MAX301CPE+ equivalent, key selection criteria include rail-to-rail analog signal handling (V− to V+), guaranteed flat on-resistance over full signal range (ΔRON ≤ 5Ω), low +85°C off-leakage (<6nA), and TTL/CMOS-compatible logic inputs with VL = +5V.
Technical Context
The MAX301CPE+ implements two independent normally-open (NO) analog switches fabricated using Maxim's silicon-gate process, enabling precise matching and low distortion across temperature. Its architecture supports rail-to-rail analog signal switching without level-shifting, with COM pins acting as drains and NO pins as sources.
Logic control is provided via IN1 and IN2 pins referenced to VL = +5V, maintaining compatibility across supply ranges. Charge injection is minimized to 15pC (typ), ensuring minimal voltage glitch during switching-critical for sample-and-hold and multiplexed data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | <35Ω max at +25°C; ensures minimal signal attenuation and gain error in precision instrumentation paths |
| On-Resistance Match | <2Ω max between channels; enables accurate differential signal routing and matched gain paths |
| Charge Injection | <15pC max; limits voltage transient on hold capacitors in sample-and-hold circuits |
| Off-Leakage Current | <6nA at +85°C; preserves signal integrity in high-impedance sensor interfaces and battery-operated systems |
| Switching Speed | Turn-on <150ns, turn-off <100ns; supports high-throughput multiplexing up to ~5MHz |
| Analog Signal Range | V− to V+ (e.g., −15V to +15V); allows unclamped DC-coupled signal routing across full supply rails |
| Supply Range | ±4.5V to ±20V bipolar or +10V to +30V single; simplifies power architecture in mixed-signal test benches |
Pinout & Package
MAX301CPE+ uses a 16-pin plastic DIP (P16-1) package with 0.3-inch body width and through-hole mounting. Pin 1 is top-left corner when notch faces up; pin numbering follows standard DIP convention (counter-clockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | COM1, COM2 | Drain terminals-common connection points for analog signals; routed to load or downstream circuitry |
| 9, 16 | NO1, NO2 | Source terminals-normally open analog outputs; connect to signal source only when corresponding IN is high |
| 10, 15 | IN2, IN1 | Digital control inputs-TTL/CMOS-compatible; active-high logic controls switch state (0 = OFF, 1 = ON) |
| 11 | V+ | Positive supply input-connects to substrate; must be ≥ |V−| + 0.3V and ≤ 44V above V− |
| 12 | VL | Logic supply reference-must be +5V for TTL compatibility; ties logic threshold to stable 5V rail |
| 13 | GND | Negative supply return-serves as reference for VL and digital interface; not analog ground |
| 14 | V− | Negative supply input-sets lower analog rail; clamps signals below V− −2V via internal diodes |
| 2–7 | N.C. | No internal connection-unbonded pads; no electrical function or thermal path |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous analog signals from V− to V+, eliminating need for external level shifters in ±15V systems |
| Guaranteed on-resistance flatness | ΔRON ≤ 5Ω over full analog range and temperature; maintains linearity in precision gain blocks and attenuators |
| Low +85°C off-leakage | <6nA ensures stable biasing in high-Z sensor front-ends and long-hold sample-and-hold applications |
| Single +5V logic supply (VL) | Enables direct interfacing with microcontroller GPIO or FPGA I/O banks without level translators |
| 44V breakdown rating | Allows safe operation with up to ±20V supplies while preserving margin against transients and ESD events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Higher supply range (±15V only), lower RON (1.3Ω typ), but higher charge injection (17pC typ) and no single-supply operation | Preferred in low-RON audio routing; unsuitable for +10V to +30V single-supply designs | Select ADG1419BRUZ only when ultra-low on-resistance is critical and supply is strictly bipolar ±15V |
| TS5A23157DCKR | Lower voltage rating (5.5V max), CMOS-only logic, smaller SC70-6 package, but higher leakage (>100nA at +85°C) | Suitable for portable consumer devices; cannot replace MAX301CPE+ in industrial/military voltage or temp ranges | Choose TS5A23157DCKR for cost-sensitive, low-voltage, space-constrained designs-not for precision or wide-temp use |
Compared with ADG1419BRUZ and TS5A23157DCKR, the MAX301CPE+ uniquely supports both wide bipolar (±4.5V to ±20V) and high single-supply (up to +30V) operation while guaranteeing <2Ω channel match and <15pC charge injection-making it irreplaceable in calibrated test gear and ruggedized comms hardware.

FAQ
What is the maximum allowable supply voltage for MAX301CPE+?
The MAX301CPE+ has an absolute maximum V+ to V− rating of 44V. It operates safely within ±4.5V to ±20V bipolar supplies or +10V to +30V single supply. Exceeding 44V differential risks permanent damage due to internal junction breakdown, per Absolute Maximum Ratings table.
Does MAX301CPE+ support single-supply operation with V− tied to ground?
Yes, MAX301CPE+ supports single-supply operation with V− = 0V and V+ = +10V to +30V. In this configuration, analog signals can swing from 0V to V+, and the device retains its specified on-resistance flatness and leakage performance-confirmed in Typical Operating Characteristics Figure MAX301-4.
What is the logic voltage requirement for controlling MAX301CPE+?
MAX301CPE+ requires VL = +5V for TTL-compatible operation. With VL = +5V, logic inputs (IN1/IN2) accept 0V–0.8V as low and 2.4V–5V as high. If VL is tied to V+, CMOS-level thresholds apply-but VL must remain within (GND − 0.3V) to (V+ + 0.3V) per Absolute Maximum Ratings.
Can MAX301CPE+ be used in sample-and-hold circuits requiring low charge injection?
Yes, MAX301CPE+ is explicitly characterized for sample-and-hold use with guaranteed charge injection ≤15pC (typ). This value ensures minimal hold-step error in 12-bit+ systems when paired with typical 10–100pF hold capacitors, as validated in Figure MAX301-7 and Electrical Characteristics table.
Is the MAX301CPE+ pinout compatible with other MAX30x variants like MAX303CPE+?
No, MAX301CPE+ is not pin-compatible with MAX303CPE+ or MAX305CPE+. While all share the same 16-pin DIP footprint, pin functions differ: MAX301CPE+ has two NO/COM pairs; MAX303CPE+ adds NC/COM for SPDT; MAX305CPE+ provides four NO/COM sets. Refer to respective Pin Configurations diagrams for exact mapping.
