Product details
Overview
The MAX301CSE from Maxim Integrated is a precision dual SPST analog switch optimized for high-accuracy signal routing in bipolar or single-supply systems. It features 35Ω max on-resistance, <2Ω channel-to-channel match, <15pC charge injection, <6nA off-leakage at +85°C, and rail-to-rail analog signal handling (V− to V+) with ±4.5V to ±20V or +10V to +30V supply operation. It is used in test equipment, military radios, and PBX systems where low distortion and timing integrity are critical.
For engineers reviewing the MAX301CSE datasheet, MAX301CSE pinout, MAX301CSE application, or MAX301CSE equivalent, this page delivers verified electrical specifications, package-specific terminal mapping, real-world use scenarios, and validated alternative parts - all grounded in Maxim's official 19-0159 Rev 1 datasheet and SO-16 package documentation.
Technical Context
The MAX301CSE implements two independent normally-open (NO) analog switches fabricated using Maxim's improved silicon-gate process. Each switch supports bidirectional signal flow with guaranteed flat on-resistance (ΔRON ≤ 5Ω over full analog range) and matched RON ≤ 2Ω between channels at +25°C.
It operates with TTL/CMOS-compatible logic inputs (VL = +5V), accepts split supplies (±4.5V to ±20V) or single positive supplies (+10V to +30V), and maintains 44V breakdown tolerance. Charge injection is tightly controlled at ≤15pC, enabling precision sample-and-hold and multiplexing without significant settling error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 35Ω - Ensures minimal signal attenuation and voltage drop across switched paths at full temperature range. |
| On-Resistance Match | ≤2Ω - Enables precise differential signal routing and matched gain paths in instrumentation front-ends. |
| Charge Injection | ≤15pC - Limits voltage glitch on hold capacitors, critical for sub-12-bit accuracy in sample-and-hold circuits. |
| Off-Leakage Current | <6nA at +85°C - Preserves long-term voltage integrity on high-impedance nodes (e.g., sensor interfaces). |
| Switching Speed | tON <150ns, tOFF <100ns - Supports multiplexing of signals up to ~3MHz without significant duty-cycle distortion. |
| Analog Signal Range | V− to V+ - Allows true rail-to-rail AC/DC signal switching without clamping or headroom loss. |
| Supply Voltage Range | ±4.5V to ±20V or +10V to +30V - Provides design flexibility across industrial, military, and telecom power architectures. |
Pinout & Package
MAX301CSE is housed in a 16-pin narrow SOIC (S16-2) package per Maxim's ordering table. Pin functions are identical to the MAX301 family's SO/DIP configuration.
| 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 outputs - connect to COM only when corresponding IN is high. |
| 10, 15 | IN2, IN1 | CMOS/TTL logic inputs - control switch state; active-high, referenced to VL. |
| 11 | V+ | Positive supply - connects to substrate; must be ≥ |V−| + 0.5V for proper biasing. |
| 12 | VL | Logic supply - fixed at +5V for TTL compatibility; ties to V+ if CMOS logic levels are used. |
| 13 | GND | Ground reference - serves as negative supply return in single-supply mode. |
| 14 | V− | Negative supply - sets lower analog rail; required for bipolar operation. |
| 2–7 | N.C. | No internal connection - floating pins; no PCB trace or thermal pad required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports input signals from V− to V+ without clipping - essential for full-scale sensor or DAC output routing. |
| Guaranteed RON flatness | ΔRON ≤ 5Ω over full analog range - eliminates gain nonlinearity in precision attenuator or calibration paths. |
| Low charge injection (≤15pC) | Minimizes sampling error in high-resolution data acquisition - enables 12-bit+ effective resolution in S/H stages. |
| TTL/CMOS logic compatibility | Accepts standard logic thresholds with VL = +5V - simplifies interface to microcontrollers and FPGAs without level-shifting. |
| 44V breakdown rating | Prevents latch-up or damage during transient overvoltage events - improves robustness in noisy military or industrial environments. |
Applications
| Test Equipment Signal Routing | Military Radio Front-End Switching |

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 | Single-supply only (±5V to ±22V not supported); 0.7Ω typical RON; higher 25pC charge injection. | Optimized for low-RON precision instrumentation, not bipolar supply environments. | Select when lowest on-resistance is prioritized over supply flexibility and charge injection. |
| TS5A23157DRCR | Lower voltage rating (5.5V max); 0.9Ω typical RON; 12pC charge injection; no guaranteed RON match spec. | Suitable for 3.3V/5V consumer electronics, not industrial/military analog signal chains. | Choose for cost-sensitive, low-voltage portable designs where ±15V operation is unnecessary. |
Compared with ADG1419BRUZ and TS5A23157DRCR, the MAX301CSE uniquely supports both bipolar and wide-range single supplies while guaranteeing RON matching and ultra-low charge injection - making it irreplaceable in high-accuracy, wide-dynamic-range analog multiplexing where supply architecture and signal fidelity are co-constrained.

FAQ
What is the maximum supply voltage rating for MAX301CSE?
The MAX301CSE has an absolute maximum V+ to V− rating of 44V. It operates safely with bipolar supplies from ±4.5V to ±20V or single positive supplies from +10V to +30V. Exceeding these ranges risks permanent damage, as confirmed in the Absolute Maximum Ratings table of Maxim's 19-0159 datasheet.
Does MAX301CSE support rail-to-rail analog signal switching?
Yes, the MAX301CSE supports true rail-to-rail analog signal handling from V− to V+. This capability is enabled by its 44V breakdown rating and internal architecture, allowing signals equal to the supply rails to pass without clipping - a key feature verified in the Electrical Characteristics table under "Analog-Signal Range".
What is the guaranteed on-resistance match between channels for MAX301CSE?
The MAX301CSE guarantees ≤2Ω on-resistance match between its two SPST channels at +25°C, and ≤3Ω over the full operating temperature range (0°C to +70°C). This specification is explicitly listed in the Electrical Characteristics table under "On-Resistance Match Between Channels".
Can MAX301CSE operate with TTL-level logic inputs?
Yes, the MAX301CSE accepts TTL-compatible logic inputs when VL is tied to +5V. Its input thresholds are specified as VINH = +2.4V (min) and VINL = +0.8V (max), satisfying standard TTL logic levels. This behavior is documented in the "INPUT" section of the Electrical Characteristics table.
What is the charge injection specification for MAX301CSE?
The MAX301CSE guarantees ≤15pC charge injection, measured under conditions of RGEN = 0Ω, CL = 10nF, and TA = +25°C. This value is critical for sample-and-hold accuracy and is explicitly stated in the Dynamic Characteristics table under "Charge Injection".
