Product details
Overview
MAX301CSE+T from Maxim Integrated is a precision dual SPST analog switch optimized for rail-to-rail signal routing in high-accuracy instrumentation and test systems. It features 35Ω max on-resistance, <2Ω channel-to-channel RON match, 15pC charge injection, 100ns max turn-off time, and operates from ±4.5V to ±20V or +10V to +30V supplies - enabling low-distortion switching of ±15V signals in sample-and-hold and military radio front-ends.
For engineers reviewing the MAX301CSE+T datasheet, MAX301CSE+T pinout, MAX301CSE+T application, or MAX301CSE+T equivalent, this page delivers verified specifications, SO-16 package details, real-world use cases in PBX line cards and battery-operated guidance systems, and two validated alternative parts with documented functional and parametric differences.
Technical Context
The MAX301CSE+T implements two independent normally-open (NO) analog switches fabricated in Maxim's silicon-gate process, delivering matched on-resistance (≤2Ω) and flat RON (≤5Ω Δ) across the full analog range (V- to V+). Its CMOS/TTL-compatible logic inputs accept VL = +5V while supporting bipolar or single-supply operation.
Charge injection is tightly controlled at ≤15pC, and off-leakage remains below 6nA at +85°C - critical for maintaining accuracy in high-impedance sample-and-hold circuits. The device achieves 150ns max turn-on and 100ns max turn-off with 44V breakdown voltage, enabling robust rail-to-rail analog signal handling without external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 35Ω - ensures minimal signal attenuation and gain error in precision gain-setting or signal multiplexing paths |
| RON Match (max) | 2Ω - guarantees matched channel gain/phase in differential or dual-path signal conditioning |
| Charge Injection (max) | 15pC - limits voltage glitch on hold capacitors, preserving DC accuracy in sample-and-hold stages |
| Turn-Off Time (max) | 100ns - enables fast channel isolation in time-division multiplexed test equipment |
| Supply Range | ±4.5V to ±20V or +10V to +30V - supports direct interfacing with ±15V op-amps and industrial sensor signal chains |
| Off-Leakage (max @ +85°C) | 6nA - prevents measurable drift in high-Z integrators or battery-monitoring inputs |
| Analog Signal Range | V- to V+ - allows full-rail switching without level-shifting circuitry in ±15V systems |
Pinout & Package
MAX301CSE+T is supplied in a 16-pin narrow SOIC (S16-2) package, 7.5mm × 5.3mm body, 1.27mm pitch, RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | COM1, COM2 | Analog common drain terminals - connect to signal path requiring switching; must remain within V- to V+ range |
| 9, 16 | NO1, NO2 | Normally-open analog source terminals - conduct only when corresponding INx = logic high |
| 10, 15 | IN2, IN1 | CMOS/TTL-compatible digital control inputs - referenced to VL; drive with +5V logic for guaranteed switching |
| 11 | V+ | Positive supply input - connects to substrate; must be powered before VL and V- to avoid latch-up |
| 12 | VL | Logic supply input - fixed at +5V for TTL compatibility; ties to V+ only if CMOS-level logic is used |
| 13 | GND | Negative supply reference - serves as return path for V-; not earth ground unless system is single-supply referenced |
| 14 | V- | Negative supply input - establishes lower analog rail; must be sequenced after V+ and VL |
| 2–7 | N.C. | No internal connection - left unconnected; no thermal or EMI impact when floating |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports continuous switching from V- to V+ (up to ±20V), eliminating need for external level shifters in ±15V systems |
| Guaranteed RON flatness (Δ5Ω max) | Maintains consistent gain and THD across full input voltage swing - essential for audio and precision ADC driver applications |
| Low 15pC charge injection | Reduces hold-step error to <1mV on 10nF capacitors, meeting requirements for 14-bit+ sample-and-hold accuracy |
| 44V breakdown rating | Prevents catastrophic failure during transient overvoltage events in military radios and industrial I/O modules |
| 35µW typical power consumption | Enables integration into battery-powered guidance systems with multi-year operational life between charges |

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 RON (1.3Ω typ), wider supply (±15V only), 12pC charge injection, LFCSP-16 package | Better performance in low-voltage (<±12V) precision data acquisition; unsuitable for ±20V or +30V single-supply systems | Select ADG1419BRUZ when operating at ±15V with sub-1Ω RON priority and PCB space is constrained. |
| TS5A23157DCUR | Lower voltage rating (5.5V max), 0.9Ω RON, 12pC charge injection, smaller SOT-23-6 package (single-channel) | Designed for low-voltage consumer electronics; cannot replace MAX301CSE+T in ±15V industrial or military signal paths | Choose TS5A23157DCUR only for cost-sensitive, battery-powered 3.3V systems where rail-to-rail ±15V capability is unnecessary. |
Compared with ADG1419BRUZ and TS5A23157DCUR, the MAX301CSE+T uniquely supports ±20V/30V operation with guaranteed RON matching and 44V breakdown - making it irreplaceable in high-voltage test fixtures, military comms, and industrial analog I/O where supply headroom and channel tracking are non-negotiable.

FAQ
What is the maximum allowable supply voltage for MAX301CSE+T?
The MAX301CSE+T has an absolute maximum rating of 44V across V+ and V−. It operates reliably over ±4.5V to ±20V bipolar supplies or +10V to +30V single supply. Exceeding ±20V or +30V risks permanent damage, even if the 44V differential limit is not breached - always observe both differential and individual rail limits specified in the Absolute Maximum Ratings table.
Does MAX301CSE+T support TTL-level logic inputs?
Yes, the MAX301CSE+T supports TTL-level logic inputs when VL is tied to +5V. With VL = +5V, the device accepts VINH ≥ +2.4V and VINL ≤ +0.8V - fully compatible with standard TTL outputs. If VL is connected to V+, CMOS-level thresholds apply (VIH ≈ 0.7×V+, VIL ≈ 0.3×V+), requiring level translation for TTL sources.
Can MAX301CSE+T switch signals beyond the supply rails?
No. The MAX301CSE+T can only switch analog signals within the range V− to V+. Signals exceeding these rails forward-bias internal protection diodes and may cause excessive current flow or latch-up. For overvoltage-tolerant switching, external clamping or dedicated fault-protected switches are required - the MAX301CSE+T provides no inherent rail-exceeding capability.
What is the thermal resistance (θJA) of the MAX301CSE+T in SO-16 package?
The MAX301CSE+T in narrow SOIC (S16-2) package has a junction-to-ambient thermal resistance (θJA) of 115°C/W, derived from its 696mW maximum power dissipation at +70°C ambient and 8.70mW/°C derating rate. This value assumes standard JEDEC 2-layer board conditions; actual θJA improves with copper pour and thermal vias.
Is MAX301CSE+T pin-compatible with other MAX30x variants in SO-16?
Yes, the MAX301CSE+T shares identical pinout and footprint with MAX303CSE and MAX305CSE in SO-16 packages. However, internal switch configuration differs: MAX301 is dual SPST (NO), MAX303 is dual SPDT (NO/NC), and MAX305 is quad SPST (NO). Swapping requires logic and signal routing changes - electrical pin compatibility does not imply functional interchangeability.
