Product details
Overview
MAX313LCPE+ from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) analog switch IC designed for precision signal routing in ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply systems. It delivers 10Ω max on-resistance, 1.5Ω max on-resistance matching between channels, and +3V logic-compatible inputs (VIH = 2.0V, VIL = 0.8V), enabling direct interface with low-voltage microcontrollers in test equipment and audio routing applications.
For engineers reviewing the MAX313LCPE+ datasheet, MAX313LCPE+ pinout, MAX313LCPE+ application, or MAX313LCPE+ equivalent, key selection considerations include rail-to-rail analog signal handling, guaranteed RON flatness (≤2Ω over signal range), crosstalk >96dB at 20kHz, and compatibility with legacy DG412 footprints in 16-pin plastic DIP packaging.
Technical Context
The MAX313LCPE+ implements a CMOS-based SPST switch architecture with four independent NO channels, each featuring symmetrical conduction and integrated ESD protection. Its logic inputs accept +3V-compatible thresholds independent of supply voltage, eliminating level-shifting requirements across its full ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operating range.
Each channel guarantees ≤10Ω on-resistance with ≤1.5Ω matching and ≤2Ω flatness over the full analog signal range, while leakage remains ≤2.5nA at +85°C. The device supports rail-to-rail analog signals and exhibits <275ns turn-on/turn-off times under 300Ω/35pF load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) - enables signal path only when logic input is high |
| On-Resistance (RON) | 10Ω max - ensures minimal insertion loss and voltage drop in precision analog paths |
| RON Matching | 1.5Ω max between channels - critical for matched gain/attenuation in multi-channel instrumentation |
| Analog Signal Range | Rail-to-rail (V− to V+) - supports full dynamic range without clipping in bipolar or unipolar systems |
| Logic Compatibility | +3V compatible (VIH = 2.0V, VIL = 0.8V) - interfaces directly with 3.3V microcontrollers and FPGAs |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - accommodates industrial, test, and telecom power architectures |
| Crosstalk | >96dB at 20kHz - prevents audible interference in audio routing and cross-channel coupling in data acquisition |
Pinout & Package
MAX313LCPE+ is housed in a 16-pin plastic DIP package (P16-2), through-hole mountable with 0.300" wide body and standard 0.1" pin pitch. Pin 1 is top-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic Control Inputs | Active-high digital inputs controlling respective NO switches; VIH = 2.0V, VIL = 0.8V |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog Common Terminals | Signal source or sink nodes - bidirectional, rail-to-rail capable |
| NO1–NO4 (Pins 3, 6, 11, 14) | Analog Normally Open Terminals | Open-circuit when IN = low; connected to COM when IN = high |
| V+ (Pin 13) | Positive Analog Supply | Accepts +4.5V to +36V (single) or +4.5V to +20V (dual); powers internal circuitry and defines upper analog rail |
| V− (Pin 4) | Negative Analog Supply | Accepts −4.5V to −20V (dual); connect to GND for single-supply operation |
| GND (Pin 5) | Ground Reference | Logic and substrate reference; must be low-impedance for noise-sensitive analog routing |
| N.C. (Pin 12) | No Connection | Not internally bonded - leave unconnected; no electrical function |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX313LEPE+ | Extended temperature range (−40°C to +85°C) vs. MAX313LCPE+ (0°C to +70°C); otherwise identical electrical specs and pinout | Suitable for industrial or automotive environments requiring wider thermal operation | Select MAX313LEPE+ when ambient operating temperature exceeds +70°C or storage below 0°C is required |
| DG412DN+ | Higher typical RON (35Ω vs. 10Ω max), higher leakage (>10nA), no guaranteed RON matching, same 16-pin DIP footprint | Legacy design reuse where ultra-low RON and matching are not critical | Choose DG412DN+ only for cost-sensitive, non-precision applications where MAX313LCPE+ is unavailable |
Compared with MAX313LEPE+, the MAX313LCPE+ offers lower cost and sufficient performance for commercial-grade test and audio equipment, while DG412DN+ provides footprint compatibility at the expense of precision analog metrics essential for modern data acquisition and low-distortion routing.

FAQ
What is the maximum analog signal voltage range supported by the MAX313LCPE+?
The MAX313LCPE+ supports rail-to-rail analog signals from V− to V+. In dual-supply mode (±4.5V to ±20V), this yields a full −20V to +20V range. In single-supply mode (+4.5V to +36V), it supports 0V to V+. This capability allows the MAX313LCPE+ to handle both bipolar sensor outputs and unipolar industrial signals without external clamping or level shifting.
Is the MAX313LCPE+ pin-compatible with the older MAX313 or DG412 devices?
Yes, the MAX313LCPE+ is explicitly pin-compatible with both the legacy MAX313 and DG412 families in 16-pin DIP packages. Pin functions-including INx, COMx, NOx, V+, V−, GND, and N.C.-match exactly. This allows direct replacement in existing designs without PCB modification, provided the improved electrical specifications of the MAX313LCPE+ (e.g., lower RON, tighter matching) are acceptable.
What is the guaranteed on-resistance matching between channels for the MAX313LCPE+?
The MAX313LCPE+ guarantees ≤1.5Ω on-resistance matching (ΔRON) between any two channels when measured at ICOM = 10mA and VNO = ±10V across the full operating temperature range. This specification is 100% tested and ensures predictable gain consistency in multi-channel instrumentation, calibration systems, and balanced signal paths where channel-to-channel tracking is critical.
Can the MAX313LCPE+ operate from a single +12V supply?
Yes, the MAX313LCPE+ fully supports single-supply operation from +4.5V to +36V. When using +12V, connect V− to GND and configure all analog signals within the 0V to +12V range. Electrical characteristics-including RON (35Ω max), leakage (<2.5nA), and switching speed (tON/tOFF < 425ns)-are specified and guaranteed under these conditions, making the MAX313LCPE+ suitable for battery-powered or compact industrial systems.
What is the maximum operating temperature range for the MAX313LCPE+?
The MAX313LCPE+ is rated for operation from 0°C to +70°C ambient temperature. This commercial-grade temperature range is validated across all electrical parameters in the datasheet, including leakage current, on-resistance, and switching timing. For extended-range applications (−40°C to +85°C), the MAX313LEPE+ variant is available with identical functionality and pinout.
