Product details
Overview
MAX319ESA+TG002 from Maxim Integrated is a precision SPDT CMOS analog switch with one normally open (NO) and one normally closed (NC) channel, 45Ω max on-resistance at ±15V supplies, <10pC charge injection, and rail-to-rail analog signal handling up to ±15.5V. It operates across –40°C to +85°C in 8-pin SO package and is used in military radios, test equipment, and guidance systems requiring low leakage and fast switching.
For engineers reviewing the MAX319ESA+TG002 datasheet, MAX319ESA+TG002 pinout, MAX319ESA+TG002 application, or MAX319ESA+TG002 equivalent, key selection criteria include guaranteed on-resistance matching (<3Ω), break-before-make timing (5–13ns), bipolar/single-supply flexibility (+10V to +30V or ±4.5V to ±20V), and ESD tolerance >±2000V.
Technical Context
The MAX319ESA+TG002 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).
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 separate VL pin, allowing compatibility with 3V or 5V control logic while maintaining full analog swing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance | 45Ω max at TA = –40°C to +85°C, ±15V supplies - ensures minimal signal attenuation and gain error in precision signal routing |
| On Resistance Match | <3Ω max between NO and NC channels - enables accurate differential or ratiometric measurements |
| Charge Injection | <10pC - reduces voltage glitch and settling time in sample-and-hold circuits |
| Off-Leakage Current | <10nA at +85°C - preserves signal integrity in high-impedance sensor interfaces |
| Switching Speed | tON < 250ns, tOFF < 210ns at ±15V - supports medium-speed multiplexing up to ~2MHz |
| Analog Signal Range | ±15.5V - allows rail-to-rail operation with ±15V supplies, compatible with industrial op-amp stages |
| ESD Rating | >±2000V per Method 3015.7 - enhances robustness in handling and board-level integration |
Pinout & Package
MAX319ESA+TG002 is housed in an 8-pin SO (Small Outline) package, 150-mil body width, with standard JEDEC MS-012AC footprint (5.0mm × 4.0mm × 1.75mm height). Pin 1 marked by bevelled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 COM | Analog common terminal | Shared signal path for both NO and NC switches; connects to load or signal source |
| 2 GND | Logic ground reference | Reference for logic input threshold and VL supply return; must be low-impedance |
| 3 V+ | Analog positive supply | Bias for internal switch transistors; sets upper analog voltage limit (up to +44V absolute max) |
| 4 VL | Logic supply input | Defines logic-high threshold (2.4V min); supports 3V or 5V control without level-shifting |
| 5 IN | Digital control input | Inverted logic sense: logic low selects NC path, logic high selects NO path |
| 6 V− | Analog negative supply | Bias for internal switch transistors; sets lower analog voltage limit (down to –44V absolute max) |
| 7 NO | Normally open analog terminal | Connects to COM only when IN = high; isolated otherwise |
| 8 NC | Normally closed analog terminal | Connects to COM when IN = low; breaks before make during transition |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports ±15.5V signals with ±15V supplies - eliminates need for external level-shifting in bipolar front-ends |
| Break-before-make switching | 5–13ns guaranteed interval prevents momentary shorting between NO and NC paths - critical for fault-tolerant routing |
| Guaranteed on-resistance flatness | ΔRON ≤ 5Ω over full analog range - maintains linearity in precision instrumentation amplifiers |
| Low power consumption | 35µW typical supply current - enables use in battery-powered portable test gear |
| TTL/CMOS logic compatibility | Accepts 0.8V/2.4V thresholds with dedicated VL pin - simplifies interface to microcontrollers and FPGAs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRMZ | Single-supply only (+5V to +36V); no bipolar support; 4.7Ω typical RON; higher 15pC charge injection | Best suited for unipolar industrial PLC I/O modules where bipolar signal handling is unnecessary | Select when operating exclusively from +12V/+24V rails and lowest possible on-resistance is prioritized over charge injection |
| TS5A3159DCKR | Lower voltage rating (5.5V max); 0.9Ω typical RON; 25pC charge injection; –40°C to +85°C grade | Targeted at low-voltage portable electronics (e.g., medical handhelds) with 3.3V logic and signal ranges ≤3.3V | Choose for cost-sensitive, low-power consumer designs where ±15V capability is not required |
Compared with ADG1419BRMZ and TS5A3159DCKR, MAX319ESA+TG002 uniquely supports true bipolar analog operation (±20V), guarantees break-before-make timing, and delivers the lowest charge injection in its voltage class-making it irreplaceable in military, aerospace, and precision test equipment where signal integrity and supply flexibility are non-negotiable.

FAQ
What is the maximum allowable supply voltage for MAX319ESA+TG002?
The MAX319ESA+TG002 has an absolute maximum rating of +44V referenced to V−, meaning V+ − V− ≤ +44V. For bipolar operation, typical use is ±15V (30V total), but it supports ±20V (40V total) within specification. Exceeding ±20V risks violating the analog signal range limits and may degrade on-resistance flatness or increase leakage.
Does MAX319ESA+TG002 support single-supply operation?
Yes, MAX319ESA+TG002 supports single-supply operation from +10V to +30V. In this mode, connect V− to GND and set VL to the desired logic level (e.g., +5V for TTL compatibility). The analog signal range becomes 0V to V+, enabling use in battery-powered systems and industrial controllers without negative rails.
What is the logic polarity relationship between IN and the NO/NC states in MAX319ESA+TG002?
In MAX319ESA+TG002, a logic low (IN ≤ 0.8V) connects COM to NC (normally closed path), while a logic high (IN ≥ 2.4V) connects COM to NO (normally open path). This inverted logic sense is fixed and documented in the truth table; no external inversion is needed unless system-level logic requires active-high control semantics.
How does temperature affect on-resistance in MAX319ESA+TG002?
On-resistance in MAX319ESA+TG002 increases with temperature: RON is typically 30Ω at +25°C and rises to 45Ω max over –40°C to +85°C. The datasheet guarantees flatness (ΔRON ≤ 5Ω) and matching (<3Ω) across this range under bipolar supply conditions, ensuring predictable performance in thermal-cycling environments like avionics or outdoor test gear.
Can MAX319ESA+TG002 be used in sample-and-hold circuits?
Yes, MAX319ESA+TG002 is explicitly recommended for sample-and-hold circuits due to its <10pC charge injection, low leakage (<10nA at +85°C), and fast, predictable switching (tON/tOFF < 250ns). These parameters minimize hold-mode droop and acquisition-time uncertainty-key requirements for high-resolution data acquisition systems.
