Product details
Overview
MAX4617EGE from Maxim Integrated is an 8-channel CMOS analog multiplexer operating from a single +2V to +5.5V supply, delivering 15ns turn-on time, 10ns turn-off time, and ≤10Ω on-resistance at +5V. It supports rail-to-rail analog signal routing with 1nA off-leakage at +25°C and TTL/CMOS-compatible logic thresholds-ideal for low-voltage data-acquisition systems and battery-powered audio signal switching.
For engineers reviewing the MAX4617EGE datasheet, MAX4617EGE pinout, MAX4617EGE application, or MAX4617EGE equivalent, key selection criteria include guaranteed on-resistance matching (≤1Ω), low crosstalk (−96dB), high off-isolation (−93dB), fast switching performance across 2.5–5.5V supplies, and compatibility with 74HC4051 pinout for drop-in replacement in legacy designs.
Technical Context
The MAX4617EGE implements a single 8:1 analog multiplexer architecture with three address inputs (A, B, C) and an active-low ENABLE control. Its BiCMOS process enables rail-to-rail analog signal handling while maintaining low charge injection (3pC) and flat on-resistance over input voltage range.
Digital interface uses 0.8V/2.4V logic thresholds at +5V supply, scaling proportionally with VCC down to +2.5V. All analog terminals feature internal ESD diodes to VCC and GND, requiring proper power sequencing but enabling robust operation in mixed-signal environments without external protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V single supply - enables direct integration into 3.3V and 5V systems without level shifting |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and gain error in precision sensor or audio paths |
| On-Resistance Match | ≤1Ω between channels at +5V - critical for matched-gain applications like differential signal routing or calibration circuits |
| Switching Times | tON = 15ns, tOFF = 10ns - supports high-speed multiplexing up to ~30MHz in 50Ω systems |
| Off-Leakage Current | 1nA at +25°C - preserves accuracy in high-impedance measurement front-ends (e.g., pH sensors, thermocouples) |
| Crosstalk / Off-Isolation | −96dB crosstalk, −93dB off-isolation - suppresses channel coupling in multi-channel data acquisition |
| Analog Signal Range | Rail-to-rail - passes full VCC–GND voltage swing without clipping, essential for ±2.5V-referenced signals |
Pinout & Package
MAX4617EGE is supplied in a 16-pin TSSOP package (U16+2 outline, 21-0066), RoHS-compliant and lead-free, with 0.65mm pitch and exposed pad not internally connected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | X0 | Analog input channel 0 - one of eight bidirectional analog terminals routed to common output X |
| 2 | X1 | Analog input channel 1 - identical electrical role to X0; interchangeable in layout |
| 3 | X2 | Analog input channel 2 - supports full 8-channel selection when used with A/B/C address lines |
| 4 | X3 | Analog input channel 3 - all X0–X7 pins are functionally symmetric and pin-compatible with 74HC4051 |
| 5 | X4 | Analog input channel 4 - no internal polarity or directionality; signals pass bidirectionally |
| 6 | X5 | Analog input channel 5 - shares same leakage, on-resistance, and bandwidth specs as X0–X3 |
| 7 | X6 | Analog input channel 6 - validated for ≤10nA leakage at +85°C per datasheet test conditions |
| 8 | X7 | Analog input channel 7 - final channel in 8:1 mux; selected when A/B/C = 111 |
| 9 | C | MSB address input - controls bit 2 of 3-bit channel select code (CBA) |
| 10 | B | Address input - controls bit 1 of channel select code; TTL/CMOS compatible at +5V |
| 11 | A | LSB address input - controls bit 0; threshold scales with VCC (e.g., 2.0V min at +3V supply) |
| 12 | ENABLE | Active-low enable - drives all switches open when high; required for power-down mode |
| 13 | X | Common analog output - bidirectional terminal connecting to selected X0–X7 channel |
| 14 | VCC | Positive supply - powers internal logic and switch elements; must be sequenced before analog signals |
| 15 | N.C. | No connection - internally unconnected; must be left floating or tied to GND per layout best practice |
| 16 | GND | Ground reference - return path for supply current and ESD diode clamping |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4051 | Direct mechanical and functional replacement in existing PCB layouts using standard 16-pin DIP/SO/TSSOP footprints |
| Guaranteed on-resistance match | ≤1Ω max difference between any two channels at +5V - eliminates gain mismatch in multi-channel instrumentation |
| Low charge injection | 3pC typical - minimizes voltage glitch on high-impedance nodes during switching, critical for sample-and-hold stability |
| Rail-to-rail analog operation | Supports signals from GND to VCC without distortion - enables use with unipolar sensors and DAC outputs |
| High-frequency isolation | −93dB off-isolation at DC, maintained >−50dB up to 10MHz - suppresses interference in RF-adjacent signal chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4581ESE+ | Same 8:1 architecture, but higher on-resistance (15Ω max at +5V) and slower switching (tON = 25ns) | Suitable for lower-speed, cost-sensitive industrial I/O where 10Ω RON is not required | Select MAX4581ESE+ only if budget constraints outweigh need for <15ns switching and ≤10Ω RON |
| 74HC4051D | Pin-compatible but higher on-resistance (80Ω typ at +4.5V), no guaranteed RON match, and no −96dB crosstalk spec | Acceptable for non-precision digital I/O or LED matrix control, not for sensor-grade analog routing | Choose 74HC4051D only for non-critical signal paths where leakage, distortion, and matching are not design-critical |

FAQ
What is the maximum supply voltage rating for MAX4617EGE?
The MAX4617EGE has an absolute maximum supply voltage of +6V referenced to GND, but its specified operational range is +2V to +5.5V. Operation above +5.5V risks permanent damage and violates the guaranteed electrical characteristics. The device is characterized and tested across the full +2V to +5.5V range, with optimal on-resistance and switching performance achieved at +5V.
Does MAX4617EGE support bidirectional analog signal flow?
Yes, MAX4617EGE supports fully bidirectional analog signal flow. All analog terminals-including X0–X7 inputs and the common X output-are electrically identical and interchangeable. Signals pass with equal performance in either direction, and the datasheet explicitly states "input and output pins are identical and interchangeable." This enables flexible routing in both source-to-load and load-to-source configurations.
What is the guaranteed on-resistance match specification for MAX4617EGE?
The MAX4617EGE guarantees ≤1Ω on-resistance match (ΔRON) between any two channels when operated at +5V supply and +25°C. This parameter is defined as RON(MAX) − RON(MIN) across all eight channels and is 100% production tested per the datasheet. At +3V supply, the match degrades to ≤2Ω, and no match guarantee is provided below +2.5V.
How does the logic threshold of MAX4617EGE scale with supply voltage?
The logic thresholds of MAX4617EGE scale linearly with VCC: at +5V supply, VIH is guaranteed ≥2.4V and VIL ≤0.8V; at +3V supply, VIH drops to ≥2.0V and VIL to ≤0.5V. This scaling maintains TTL/CMOS compatibility across the full +2.5V to +5.5V operating range and is verified by design-not just typical behavior-as noted in the datasheet's Note 6.
Is MAX4617EGE pin-compatible with the 74HC4051 family?
Yes, MAX4617EGE is fully pin-compatible with the industry-standard 74HC4051 in 16-pin DIP, SO, and TSSOP packages. The pin nomenclature, address logic (A/B/C), ENABLE polarity, and X0–X7/X terminal mapping match exactly. However, MAX4617EGE offers superior analog performance-including lower on-resistance, faster switching, and tighter matching-making it a functional upgrade without PCB changes.
