Product details
Overview
The MAX4648EUT+TG077 from Maxim Integrated is a single-pole/single-throw (SPST) normally open analog switch in SOT23-6 package, operating from ±4.5V to ±20V dual supplies or +9V to +36V single supply. It delivers 25Ω max on-resistance with ≤2Ω flatness over rail-to-rail signal range, 1nA max off-leakage at +25°C, and 100ns switching times (tON/tOFF). It is used for precision signal routing in telecom line cards and test instrumentation.
For engineers reviewing the MAX4648EUT+TG077 datasheet, MAX4648EUT+TG077 pinout, MAX4648EUT+TG077 application, or MAX4648EUT+TG077 equivalent, key selection criteria include guaranteed RON flatness, dual-supply rail-to-rail analog handling, low charge injection (4pC), and compatibility with ±15V or +12V system power rails.
Technical Context
The MAX4648EUT+TG077 implements a CMOS transmission-gate architecture with logic-controlled gate drive, enabling bidirectional analog/digital signal conduction without polarity restriction. Its control input accepts standard TTL/CMOS logic levels (VIH = 2.4V, VIL = 0.8V) independent of supply voltage, eliminating need for separate VL logic supply.
It supports true rail-to-rail analog operation: signal range extends from V− to V+, with internal ESD protection diodes clamping inputs beyond supply rails. Off-isolation reaches −92dB at 1MHz, and THD remains ≤0.006% across 20Hz–20kHz with 5Vp-p signal into 600Ω load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 25Ω max at ±15V supplies - ensures minimal signal attenuation and gain error in precision analog paths |
| RON Flatness | 2Ω max over full signal range - maintains consistent channel gain across varying input voltages |
| Off-Leakage Current | 1nA max at +25°C - preserves high-impedance node integrity in sample-hold and multiplexer circuits |
| Switching Speeds | tON = tOFF = 100ns typ - supports >1MHz signal routing without timing skew in data acquisition systems |
| Charge Injection | 4pC typ - limits voltage glitch on sampled capacitors, critical for ADC front-end accuracy |
| Analog Signal Range | Rail-to-rail (V− to V+) - enables full dynamic range utilization in bipolar and unipolar signal chains |
| Supply Voltage Range | Dual: ±4.5V to ±20V; Single: +9V to +36V - accommodates industrial, telecom, and test equipment power architectures |
Pinout & Package
SOT23-6 package (U6SN-1 code), 2.9mm × 1.6mm footprint, 1.1mm height, lead-free (RoHS-compliant). Thermal resistance θJA = 115°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO (Normally Open) | Analog switch output terminal - connects to COM only when IN = HIGH; open-circuit otherwise |
| 2 | V− | Negative supply rail - must be connected for dual-supply operation; tied to GND for single-supply use |
| 3 | IN | Digital control input - active-HIGH logic controls NO-COM path; no external pull-up required |
| 4 | GND | Ground reference - serves as return path for logic and supply currents; decoupling capacitor recommended |
| 5 | V+ | Positive supply rail - powers analog switch core and input buffer; supports up to +36V |
| 6 | COM | Analog common terminal - bidirectional signal port shared between NO and internal switch element |
Key Features
| Feature | Design Value |
|---|---|
| No VL logic supply required | Logic threshold referenced to V+ and GND - eliminates need for auxiliary 3.3V/5V rail in mixed-voltage systems |
| Rail-to-rail analog signal handling | Signal range spans full V− to V+ - avoids clipping in ±12V op-amp stages and audio line drivers |
| Guaranteed RON flatness | ≤2Ω variation across −10V to +10V - ensures linear gain response in programmable-gain amplifier switches |
| Low charge injection (4pC) | Minimizes settling error after switching - enables accurate DC-coupled sampling in 16-bit+ data converters |
| High off-isolation (−92dB @1MHz) | Reduces crosstalk between adjacent channels - critical in multi-channel telecom multiplexers and ATE systems |
Applications
| Telecom Line Cards | Automated Test Equipment (ATE) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRMZ-REEL | 2.5Ω max RON, ±15V supply, 10ns switching, but requires VL logic supply (2.7V–5.5V) | Better RON and speed, but adds complexity in systems lacking dedicated logic rail | Select when ultra-low on-resistance and fast settling outweigh logic supply overhead |
| TS5A23157DGSR | 0.9Ω max RON, +1.65V to +5.5V single supply only, 30ns switching, 50pC charge injection | Optimized for low-voltage portable gear; incompatible with ±15V or high-voltage industrial rails | Select for battery-powered instrumentation with 3.3V logic and <1V signal swing |
Compared with ADG1419BRMZ-REEL and TS5A23157DGSR, the MAX4648EUT+TG077 uniquely supports wide dual-supply operation (±4.5V to ±20V) without auxiliary logic voltage, making it optimal for legacy telecom and industrial test systems where supply architecture constraints preclude adding new rails.

FAQ
What is the maximum supply voltage rating for MAX4648EUT+TG077?
The MAX4648EUT+TG077 supports dual supplies up to ±20V (V+ to V− ≤ 44V) and single supplies up to +36V. Absolute maximum ratings specify V+ ≤ +44.0V, V− ≥ −44.0V, and V+ to V− ≤ +44.0V. Exceeding these stresses may cause permanent damage. The device is fully specified from ±4.5V to ±20V dual or +9V to +36V single supply.
Does MAX4648EUT+TG077 require a separate logic supply voltage (VL)?
No, the MAX4648EUT+TG077 does not require a separate VL logic supply. Its digital input (IN) accepts standard TTL/CMOS logic thresholds (VIH = 2.4V, VIL = 0.8V) referenced to V+ and GND, enabling direct interfacing with microcontrollers or FPGAs operating at 3.3V or 5V without level-shifting circuitry.
What is the typical charge injection value for MAX4648EUT+TG077 and why does it matter?
The MAX4648EUT+TG077 exhibits 4pC typical charge injection. This parameter quantifies the net charge dumped onto the COM node during switching transitions. In sample-and-hold or switched-capacitor circuits, excessive charge injection causes voltage glitches and settling errors; 4pC enables accurate DC-coupled sampling in 16-bit+ data acquisition systems.
Can MAX4648EUT+TG077 operate with a single +12V supply?
Yes, the MAX4648EUT+TG077 is fully specified for single +12V operation (V+ = +12V, V− = GND). In this configuration, its on-resistance is 60Ω max, RON flatness is 8Ω max, and switching times increase to 175ns (tON) and 150ns (tOFF). All logic and analog functionality remains intact, supporting applications like PC multimedia boards and industrial I/O modules.
What is the off-isolation performance of MAX4648EUT+TG077 at high frequencies?
The MAX4648EUT+TG077 achieves −92dB off-isolation at 1MHz under 50Ω conditions. However, off-isolation degrades with increasing frequency due to channel capacitance (CNO(OFF) = CCOM(OFF) = 6pF). Above 5MHz, board layout becomes critical; isolation drops to −30dB at 100MHz. For RF applications, use guard traces and minimize parasitic capacitance to maintain signal integrity.
