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 or +10V to +30V supplies, delivering <35Ω on-resistance (typ. 22Ω), <2Ω channel-to-channel match, and <15pC charge injection - enabling high-accuracy signal routing in test equipment and military radios.
For engineers reviewing the MAX301CPE datasheet, MAX301CPE pinout, MAX301CPE application, or MAX301CPE equivalent, this device is selected for rail-to-rail analog switching, low-leakage sample-and-hold circuits, and systems requiring guaranteed on-resistance flatness (Δ3Ω max) across temperature and signal range.
Technical Context
The MAX301CPE implements two independent normally-open (NO) analog switches fabricated using Maxim's silicon-gate process, supporting bipolar (±4.5V to ±20V) or single-supply (+10V to +30V) operation while maintaining TTL/CMOS logic compatibility via dedicated VL pin. Its architecture ensures matched RON between channels and minimal ΔRON over full analog swing (VANA = V− to V+).
Charge injection is tightly controlled at ≤15pC (guaranteed), and off-leakage remains below 6nA at +85°C - critical for precision sampling and battery-operated systems. The device achieves turn-on/turn-off times of <150ns/<100ns with 44V breakdown tolerance, enabling robust rail-to-rail signal handling without external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | ≤35Ω max at +25°C; enables low insertion loss in signal paths up to ±15V analog swing |
| RON Match Between Channels | ≤2Ω max; ensures matched gain/attenuation in differential or dual-path circuits |
| On-Resistance Flatness (ΔRON) | ≤3Ω max over full analog range; preserves linearity in precision instrumentation |
| Charge Injection | ≤15pC guaranteed; minimizes sampling error in ADC front-ends and sample-and-hold stages |
| Off-Leakage Current | ≤6nA at +85°C; maintains accuracy in high-impedance sensor interfaces and long-hold applications |
| Switching Speed | tON < 150ns, tOFF < 100ns; supports >5MHz multiplexing in automated test equipment |
| Analog Signal Range | VANA = V− to V+; allows true rail-to-rail signal switching without level-shifting |
Pinout & Package
MAX301CPE uses a 16-pin plastic DIP (P16-1) package with 0°C to +70°C operating temperature range. Pin functions are validated per Maxim's official pin description table and top-view schematic.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | COM1, COM2 | Common analog terminals - bidirectional signal path endpoints for each SPST switch |
| 9, 16 | NO1, NO2 | Normally-open analog switch outputs - connect to signal source only when enabled |
| 10, 15 | IN1, IN2 | Digital control inputs - TTL/CMOS-compatible; active-high logic enables respective switch |
| 11 | V+ | Positive supply input - also substrate connection; must be powered first in sequencing |
| 12 | VL | Logic supply input - set to +5V for TTL compatibility; ties to V+ for CMOS-level operation |
| 13 | GND | Negative supply reference - used as ground return for bipolar operation |
| 14 | V− | Negative supply input - defines lower bound of analog signal range |
| 2–7 | N.C. | No internal connection - electrically isolated; no routing or termination required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports VANA = V− to V+ (up to ±20V or +30V), eliminating need for external level shifters |
| Guaranteed RON matching | ≤2Ω max mismatch between channels - essential for balanced signal paths and differential switching |
| Low charge injection | ≤15pC (guaranteed) - reduces hold-step error in precision sample-and-hold circuits |
| Bipolar or single-supply operation | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-signal systems |
| TTL/CMOS logic compatibility | Configurable via VL pin: +5V for TTL, tied to V+ for CMOS - avoids external logic translators |

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 |
|---|---|---|---|
| ADG201AKNZ | Higher RON (60Ω typ), wider temp range (−40°C to +85°C), no VL pin - requires external logic level translation | Preferred where extended temperature operation is mandatory but charge injection ≤25pC is acceptable | Select ADG201AKNZ only if system requires −40°C rating and can tolerate higher on-resistance and leakage |
| TS5A23157DCKR | Lower voltage rating (5.5V max), CMOS-only logic, smaller SC70-6 package - not pin-compatible or voltage-compatible | Suitable for low-voltage portable electronics, not for ±15V industrial/military signal routing | Choose TS5A23157DCKR only for 3.3V/5V systems where size and cost outweigh high-voltage performance needs |
Compared with MAX301CPE, ADG201AKNZ trades lower leakage at cold temperatures for higher RON and no VL flexibility, while TS5A23157DCKR offers miniaturization at the expense of voltage range and precision - neither is pin-compatible, and both require redesign for MAX301CPE replacement.

FAQ
What is the maximum analog signal voltage range supported by the MAX301CPE?
The MAX301CPE supports analog signals from V− to V+, with absolute maximum ratings of ±4.5V to ±20V for bipolar supplies or +10V to +30V for single supply. Its 44V breakdown voltage enables true rail-to-rail switching - for example, ±15V supplies allow ±15V analog signals without clipping or distortion. This specification is guaranteed across the 0°C to +70°C operating range of the MAX301CPE.
Does the MAX301CPE require a separate logic supply voltage (VL), and what happens if it's unconnected?
Yes, the MAX301CPE requires VL to be actively driven: +5V for TTL compatibility or tied to V+ for CMOS-level operation. If VL is left floating, input thresholds become undefined and switching behavior is unreliable. The MAX301CPE datasheet specifies that VL must be connected - it is not internally generated. Leaving VL unconnected risks incorrect channel activation or increased input current in the MAX301CPE.
Can the MAX301CPE be used in sample-and-hold circuits, and what parameter most affects hold-step accuracy?
Yes, the MAX301CPE is explicitly designed for sample-and-hold applications due to its guaranteed ≤15pC charge injection - the dominant factor affecting hold-step error. Low on-resistance (<35Ω) and matched channels further reduce settling errors. These parameters are tested and specified across temperature for the MAX301CPE, making it suitable for precision data acquisition systems where hold-mode fidelity is critical.
What is the guaranteed on-resistance match between the two switches in the MAX301CPE, and why does it matter?
The MAX301CPE guarantees ≤2Ω maximum on-resistance match between its two SPST switches at +25°C, and ≤3Ω across the full operating temperature range. This tight matching ensures identical gain/loss in dual-path systems - such as differential signal routing or balanced test fixtures - preventing amplitude imbalance that would degrade common-mode rejection or measurement accuracy in the MAX301CPE application.
Is the MAX301CPE pin-compatible with other variants like MAX301EPE or MAX301CSE?
No, the MAX301CPE is not pin-compatible with MAX301EPE (same package but extended −40°C to +85°C rating) or MAX301CSE (16-pin narrow SO package). While all share identical pin functions, the MAX301CPE uses a 16-pin plastic DIP (P16-1) footprint distinct from SOIC or CERDIP packages. PCB layout must match P16-1 mechanical dimensions - substitution requires physical board revision, even though electrical behavior is consistent across the MAX301 family.
