Product details
Overview
MAX319ESA+TG069 from Maxim Integrated is a precision SPDT CMOS analog switch with one normally open (NO) and one normally closed (NC) channel, 45Ω maximum on-resistance at TMIN to TMAX, ±20V bipolar or +10V to +30V single-supply operation, and rail-to-rail analog signal handling up to ±15.5V - used in military radios and guidance systems requiring low charge injection and high off-isolation.
For engineers reviewing the MAX319ESA+TG069 datasheet, MAX319ESA+TG069 pinout, MAX319ESA+TG069 application, or MAX319ESA+TG069 equivalent, key selection criteria include guaranteed on-resistance matching (<2Ω), break-before-make timing (5–13ns), <10pC charge injection, and SO-8 package compatibility with industrial temperature range (-40°C to +85°C).
Technical Context
The MAX319ESA+TG069 implements a single-pole double-throw (SPDT) topology with independent NO and NC paths controlled by a single TTL/CMOS-compatible logic input. Its silicon-gate process ensures matched on-resistance between channels and flat RON over the full analog signal range (±15.5V at ±16.5V supplies).
It supports dual-supply operation (±4.5V to ±20V) and single-supply mode (+10V to +30V), with V− tied to GND in unipolar configurations. Logic-level translation is enabled via dedicated VL pin, allowing interface with 3.3V or 5V controllers while maintaining analog integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| On Resistance (max) | 45Ω over full temperature range (−40°C to +85°C), enabling <10mV drop at 10mA |
| On Resistance Match | ≤2Ω between NO and NC channels at +25°C, critical for differential signal switching |
| Charge Injection | ≤10pC, minimizing voltage glitch in sample-and-hold circuits |
| Off-Leakage (max) | 10nA at +85°C, preserving signal integrity in high-impedance sensor interfaces |
| Break-Before-Make Delay | 5–13ns, preventing momentary shorting in power-path or signal-routing applications |

Pinout & Package
MAX319ESA+TG069 is housed in an 8-pin SO (Small Outline) package, 150-mil body width, with standard JEDEC MS-012AC footprint (5.0mm × 4.0mm, 1.27mm pitch). Pin 1 marked by bevelled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | COM | Analog common terminal - connects to either NO or NC based on logic state |
| 2 | N.C. | No connect - not internally bonded; leave unconnected |
| 3 | GND | Digital logic ground reference for IN and VL inputs |
| 4 | V+ | Positive analog supply - sets upper analog rail; supports up to +44V absolute max |
| 5 | VL | Logic supply input - accepts 3V to 5.25V; decouples logic thresholds from analog rails |
| 6 | IN | Active-high digital control input - TTL/CMOS compatible; drives internal switch matrix |
| 7 | V− | Negative analog supply - sets lower analog rail; supports down to −44V absolute max |
| 8 | NC | Normally closed analog terminal - conducts when IN = LOW |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog handling | Supports signals from V− to V+ without clipping - essential for ±15V op-amp interfacing |
| Guaranteed RON flatness | ΔRON ≤ 5Ω over full analog range (−15.5V to +15.5V), ensuring consistent gain in precision gain-switching |
| ESD robustness | ≥±2000V per MIL-STD-3015.7 - eliminates need for external protection in ruggedized systems |
| Bipolar/single-supply flexibility | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-signal boards |
| Low power consumption | 35µW typical supply current - enables use in battery-powered test equipment with multi-year runtime |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the operating temperature range for MAX319ESA+TG069?
The MAX319ESA+TG069 is specified for −40°C to +85°C operation, confirmed in the Ordering Information table where "ESA" suffix denotes the extended temperature grade. This range is validated across all electrical parameters including on-resistance, leakage, and switching times - critical for deployment in avionics and industrial control systems.
Does MAX319ESA+TG069 support single-supply operation?
Yes, MAX319ESA+TG069 supports single-supply operation from +10V to +30V. Per Applications Information, V− must be tied to GND, and VL should be set to +5V for TTL compatibility or to V+ for CMOS logic levels - enabling seamless integration into systems with only a positive rail.
What is the maximum analog signal voltage the MAX319ESA+TG069 can handle?
The MAX319ESA+TG069 supports analog signals from V− to V+, with absolute maximum ratings of V+ ≤ (V− + 44V). When operated at ±16.5V supplies, it reliably handles ±15.5V signals - verified in Electrical Characteristics tables under "Analog-Signal Range" and "Off Leakage Current" test conditions.

Yes, MAX319ESA+TG069 shares identical SO-8 pinout with MAX317ESA and MAX318ESA - confirmed in Pin Configurations and Pin Description sections. All three use pins 1 (COM), 3 (GND), 4 (V+), 5 (VL), 6 (IN), 7 (V−), and 8 (NC or NO), differing only in internal switch configuration (NC/NO/SPDT).
What logic families are compatible with the MAX319ESA+TG069 control input?
The MAX319ESA+TG069 IN pin is TTL- and CMOS-logic compatible, accepting VINH ≥ 2.4V and VINL ≤ 0.8V at VL = 5V. Its logic threshold is referenced to VL (not V+ or GND), allowing direct interface with 3.3V microcontrollers when VL = 3.3V - verified in Electrical Characteristics under "Logic Input Current".
