Analog Devices Inc./Maxim Integrated MAX4614EGE

Overview

MAX4614EGE from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open CMOS analog switch designed for low-voltage signal routing in precision analog and mixed-signal systems. It operates from +2V to +5.5V, delivers 10Ω max on-resistance at +5V, 12ns turn-on time, <6nA off-leakage at +85°C, and supports rail-to-rail analog signals from GND to V+. It is used in battery-powered audio routing and low-voltage data-acquisition front-ends.

For engineers reviewing the MAX4614EGE datasheet, MAX4614EGE pinout, MAX4614EGE application, or MAX4614EGE equivalent, key selection criteria include guaranteed on-resistance matching (≤1Ω), flatness over signal range (≤1Ω), TTL/CMOS logic compatibility at +5V, and TSSOP-14 packaging with verified thermal performance across -40°C to +85°C.

Technical Context

The MAX4614EGE implements four independent SPST NO switches using matched CMOS transmission-gate topology, enabling simultaneous control of discrete analog paths without crosstalk-induced distortion. Its logic inputs accept 0.8V/2.4V thresholds, ensuring reliable switching under +5V TTL/CMOS drive while maintaining sub-10ns propagation delay asymmetry.

Each channel handles bidirectional analog signals from GND to V+ with ≤1Ω on-resistance variation across the full 0–V+ range and ≤1Ω match between channels - critical for multiplexed instrumentation where gain/offset tracking matters. Off-isolation exceeds -85dB at 100kHz, and charge injection is limited to 6.5pC, supporting precision sample-and-hold accuracy.

Key Specifications

Pinout & Package

MAX4614EGE is housed in a 14-pin TSSOP package (4.4mm × 5mm, 0.65mm pitch), optimized for thermal dissipation and board-space efficiency in portable designs. The exposed pad variant (EGE suffix) enhances thermal performance for sustained operation at elevated ambient temperatures.

FAQ

What is the maximum supply voltage rating for MAX4614EGE?

The absolute maximum supply voltage for MAX4614EGE is +6V. Operation above this level risks permanent damage. The device is specified for reliable operation from +2V to +5.5V, with on-resistance and switching times characterized across that full range. At +5.5V, on-resistance remains ≤10Ω and off-leakage stays below 6nA at +85°C - confirming robustness within its rated window. Always observe proper power sequencing: apply V+ before analog or logic signals.

Does MAX4614EGE support rail-to-rail analog signal handling?

Yes, MAX4614EGE supports true rail-to-rail analog signal handling from GND to V+. Its CMOS transmission-gate architecture allows bidirectional signal passage across the entire supply range without clamping or distortion. This is confirmed in the datasheet's "Analog Signal Range" parameter (0V to V+), and validated by typical operating curves showing flat on-resistance from 0V to V+ at multiple supply voltages. No external biasing is needed for full-range signal integrity.

What is the logic threshold compatibility of MAX4614EGE at +5V supply?

At +5V supply, MAX4614EGE features TTL/CMOS-compatible logic thresholds: VIN_L = 0.8V (max) and VIN_H = 2.4V (min). This ensures direct interfacing with standard 5V microcontrollers, FPGAs, and logic families without level shifters. Input current remains below ±10nA across temperature, minimizing loading on driving sources. These thresholds are guaranteed over the full -40°C to +85°C operating range, not just at +25°C.

How does MAX4614EGE perform in terms of channel-to-channel on-resistance matching?

MAX4614EGE guarantees ≤1Ω maximum difference in on-resistance between any two channels (ΔRON), measured under identical conditions (e.g., V+ = +5V, ICOM = 10mA). This matching is process-trimmed and tested - not just typical - and holds across temperature (-40°C to +85°C) and signal voltage (0V to V+). It directly enables ratiometric accuracy in multi-channel sensor systems where relative gain error must stay below 0.1%.

Is MAX4614EGE pin-compatible with industry-standard analog switches?

Yes, MAX4614EGE is pin-compatible with the industry-standard 74HC4066 and MAX4610 analog switches. Its 14-pin TSSOP footprint, pin numbering, and functional assignment (e.g., COM/NO/IN layout) match those legacy parts exactly - allowing drop-in replacement in existing designs. This compatibility extends to electrical behavior: similar on-resistance, leakage, and timing specs ensure no PCB or firmware changes are needed when upgrading from 74HC4066 to MAX4614EGE.
