Product details
Overview
MAX4615EGE from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally closed (NC) CMOS analog switch operating from a single +2V to +5.5V supply. It delivers 10Ω max on-resistance at +5V, 1Ω max channel-to-channel on-resistance match, and rail-to-rail signal handling from V+ to GND. Its 10ns turn-off time and <6nA off-leakage at +85°C support precision low-voltage signal routing in battery-powered instrumentation.
For engineers reviewing the MAX4615EGE datasheet, MAX4615EGE pinout, MAX4615EGE application, or MAX4615EGE equivalent, key selection criteria include guaranteed on-resistance flatness (1Ω max), TTL/CMOS logic compatibility at +5V, and NC switching behavior across all four channels - critical for fail-safe signal path control in portable medical sensors and audio multiplexers.
Technical Context
The MAX4615EGE implements four independent bidirectional NC analog switches controlled by active-low digital inputs. Each switch features matched on-resistance (≤1Ω variation between channels) and flat on-resistance (≤1Ω variation over full signal range), enabling accurate gain/offset matching in multi-channel data acquisition front-ends.
It operates with guaranteed logic thresholds of +0.8V (VIL) and +2.4V (VIH) at +5V supply, ensuring interoperability with standard TTL and CMOS drivers without level-shifting. Signal routing supports rail-to-rail analog voltages (0V to V+) with ≤6nA off-leakage at +85°C and 12ns tON/10ns tOFF switching performance.

Pinout & Package
MAX4615EGE is housed in a 14-pin TSSOP package (4.4mm × 5mm, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 14 is V+, pin 7 is GND, and pins 1–4 and 11–13 serve as analog and control terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pin 14) | Positive supply rail | Must be applied before analog signals to prevent latch-up; supports 2V–5.5V operation |
| GND (Pin 7) | Reference ground | Common return for analog signals, logic inputs, and power supply |
| IN1–IN4 (Pins 5,6,12,13) | Digital control inputs | Active-low: logic LOW closes NC switch; logic HIGH opens it |
| NC1–NC4 (Pins 1,3,8,10) | Normally closed analog terminals | Connected to COMx when INx = LOW; open when INx = HIGH |
| COM1–COM4 (Pins 2,4,9,11) | Common analog terminals | Bidirectional signal path shared with corresponding NCx terminal |
Key Features

FAQ
What is the maximum allowable supply voltage for MAX4615EGE?
The absolute maximum supply voltage for MAX4615EGE is +6V. Operation above +5.5V violates the recommended operating conditions and risks permanent damage. The device is specified for reliable operation from +2V to +5.5V, with on-resistance and leakage parameters guaranteed across this range. Exceeding +6V may trigger internal diode conduction and degrade long-term reliability, even if functional temporarily.
Does MAX4615EGE support rail-to-rail analog signals?
Yes, MAX4615EGE supports rail-to-rail analog signal handling from GND to V+. This means analog voltages spanning the full supply range (e.g., 0V to +5V when V+ = +5V) can pass through the NC switches without clipping or distortion. The specification is verified across temperature and supply voltage, enabling full utilization of ADC input ranges and preserving signal fidelity in low-voltage systems.
How does the NC (normally closed) configuration of MAX4615EGE behave during power-up?
During power-up, MAX4615EGE defaults to its NC state: all four switches remain closed until a valid logic HIGH is applied to their respective INx pins. This fail-safe behavior ensures signal continuity in case of controller reset or initialization delay. The device draws only 1µA quiescent current in this state, making it ideal for systems requiring uninterrupted analog paths during boot sequences.
Can MAX4615EGE replace a 74HC4066 in an existing design?
Yes, MAX4615EGE is explicitly pin-compatible with the 74HC4066 and MAX4610, sharing identical pinout, logic polarity, and package footprint. However, MAX4615EGE improves upon the 74HC4066 with lower on-resistance (10Ω vs. typical 105Ω), tighter matching (1Ω vs. unspecified), and guaranteed rail-to-rail operation - requiring no PCB changes but delivering measurable performance gains in precision analog paths.
What is the guaranteed on-resistance match between channels for MAX4615EGE?
The guaranteed on-resistance match for MAX4615EGE is 1Ω maximum across all four channels at +5V supply. This parameter (∆RON = RON(max) − RON(min)) is tested and specified over temperature and signal range, ensuring consistent gain scaling in multi-channel instrumentation amplifiers and differential signal routing where channel imbalance must be minimized.
