Product details
Overview
MAX998EUT+TG069 from Maxim Integrated is a single, high-speed, low-power comparator optimized for +2.7V to +5.5V single-supply operation. It delivers 20ns propagation delay, 225µA supply current per comparator, and features rail-to-rail output with ground-sensing inputs (–0.2V to VCC – 1.2V common-mode range). It is used in IR receivers, battery-powered threshold detection, and 3V digital line receivers.
For engineers reviewing the MAX998EUT+TG069 datasheet, MAX998EUT+TG069 pinout, MAX998EUT+TG069 application, or MAX998EUT+TG069 equivalent, key selection criteria include shutdown current (1nA), input hysteresis (0.5–4.0mV), output leakage (<200nA), and SOT23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX998EUT+TG069 employs a CMOS input stage with internal hysteresis to prevent oscillation on slow-moving or noisy inputs, ensuring clean switching even near trip points. Its push-pull output drives CMOS/TTL logic directly without external pull-ups and tolerates continuous short-circuit faults to either rail.
Shutdown is controlled via the SHDN pin: driven low to place the output in high-impedance state and reduce ICC to 1nA; driven high or tied to VCC for normal operation. SHDN logic thresholds scale with VCC (VIL = 0.2×VCC, VIH = 0.65×VCC), enabling 5V logic control of a 3V-operated device.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 20ns typical at 50mV overdrive - enables high-speed signal discrimination in timing-critical circuits. |
| Supply Current | 225µA per comparator - supports ultra-low-power operation in battery-powered systems. |
| Shutdown Current | 1nA typical - reduces system standby power by >99.9% versus active mode. |
| Input Common-Mode Range | –0.2V to (VCC – 1.2V) - allows ground-referenced sensing and interface with sub-VCC analog signals. |
| Rail-to-Rail Output | VOH ≥ VCC – 0.4V, VOL ≤ 0.4V at 2mA - ensures full logic-level compatibility with 3.3V/5V CMOS/TTL without external components. |
| Input Offset Voltage | ±2mV max (±3mV over temperature) - provides accurate threshold detection in precision discriminator applications. |
| Hysteresis | 0.5–4.0mV input-referred - suppresses noise-induced chatter without requiring external feedback resistors. |
Pinout & Package
MAX998EUT+TG069 is housed in a RoHS-compliant 6-pin SOT23-6 package (outline 21-0058), with 0.95mm pitch, 2.9mm × 1.6mm footprint, and thermal pad not connected internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output stage; must be connected to low-impedance system ground plane. |
| 2 | IN– | Inverting input; accepts common-mode voltages down to –0.2V, enabling ground-sensing configurations. |
| 3 | IN+ | Noninverting input; same common-mode range as IN–; differential input voltage determines output state. |
| 4 | OUT | Push-pull output; actively drives high or low; enters high-Z state during shutdown. |
| 5 | VCC | Positive supply input; operates from 2.7V to 5.5V; requires local 0.1µF ceramic decoupling capacitor. |
| 6 | SHDN | Active-low shutdown control; high-impedance input; must be driven (not left floating) to avoid indeterminate operation. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | 2.7V to 5.5V range eliminates need for dual supplies in portable and industrial 3V/5V systems. |
| Internal hysteresis | 0.5–4.0mV input-referred band prevents false triggering from noise or slow edges without external components. |
| Rail-to-rail output | Drives full VCC and GND logic levels directly into CMOS/TTL loads - no pull-up resistors required. |
| Ground-sensing inputs | Common-mode range extends 200mV below GND - supports direct interface with current-output sensors (e.g., photodiodes). |
| Short-circuit tolerant I/O | All pins withstand continuous fault conditions to either rail - improves robustness in harsh or miswired environments. |
Applications
| IR Receiver Front-End | Battery Voltage Threshold Detector |
|---|---|
Use Scenario: Detects modulated infrared pulses from remote controls using a photodiode and load resistor. IC Role / Device Role / Timing Role: Comparator compares photodiode voltage against a reference to generate clean digital output pulses.

IC Role / Device Role / Timing Role: Compares battery voltage against precision reference to assert flag when voltage drops below 3.0V. Use Value: Ground-sensing input allows direct connection to battery negative terminal; 225µA quiescent current minimizes drain on aging cells. |
| Digital Line Receiver | 3V Logic-Level Translator |
Use Scenario: Receives and cleans up degraded digital signals in noisy industrial bus environments. IC Role / Device Role / Timing Role: High-speed comparator restores signal integrity by regenerating logic levels with precise thresholds. Use Value: 20ns delay enables reliable reception of >20MHz data rates; internal hysteresis rejects EMI-induced glitches on long traces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7215M5X/NOPB | 25ns propagation delay, 240µA supply current, no shutdown pin, SOT23-5 package (5-pin, no SHDN) | Lacks shutdown functionality and has one fewer pin; unsuitable where 1nA standby is required. | Select only if shutdown is unnecessary and board layout accommodates different pinout. |
| TLV3501DBVR | 4.5ns propagation delay, 5.3mA supply current, no shutdown, rail-to-rail input (not ground-sensing), SOT23-6 | Higher speed but 23× higher active current; input range does not extend below GND - incompatible with photodiode biasing. | Choose only for ultra-high-speed applications where power budget permits and ground-sensing is not needed. |
Compared with LMV7215M5X/NOPB and TLV3501DBVR, MAX998EUT+TG069 uniquely balances nanosecond-speed response (20ns), ultra-low active current (225µA), true ground-sensing capability, and integrated shutdown (1nA), making it optimal for space- and power-constrained 3V systems requiring robust analog front-end conditioning.

FAQ
What is the shutdown behavior of the MAX998EUT+TG069?
When the SHDN pin is driven low, the MAX998EUT+TG069 disables its internal comparator circuitry, places the OUT pin in a high-impedance state, and reduces supply current to 1nA typical. The device wakes up in 15µs (typical) after SHDN is driven high. Leaving SHDN floating is prohibited - it must be actively driven to avoid indeterminate operation. This behavior is fully specified in the Electrical Characteristics table under ISD and tEN parameters for MAX998EUT+TG069.
Does the MAX998EUT+TG069 support ground-referenced input signals?
Yes, the MAX998EUT+TG069 supports ground-referenced inputs: its common-mode voltage range extends to –0.2V, allowing the IN+ or IN– pin to be biased at or slightly below ground potential. This enables direct interface with current-output transducers like photodiodes without level-shifting circuitry. The specification is confirmed in the Electrical Characteristics table (VCMR = –0.2V to VCC – 1.2V) and Detailed Description section for MAX998EUT+TG069.
Can the MAX998EUT+TG069 drive standard CMOS/TTL logic directly?
Yes, the MAX998EUT+TG069 features rail-to-rail push-pull outputs capable of sourcing/sinking 2mA while maintaining VOH ≥ VCC – 0.4V and VOL ≤ 0.4V - fully compatible with 3.3V and 5V CMOS/TTL logic families without external pull-up resistors. This is verified in the Electrical Characteristics table (VOH/VOL specs) and General Description, confirming direct interfacing capability for MAX998EUT+TG069.
What is the maximum capacitive load the MAX998EUT+TG069 can drive while maintaining 20ns propagation delay?
The MAX998EUT+TG069 maintains its 20ns typical propagation delay with CLOAD ≤ 15pF, as shown in Typical Operating Characteristic TOC06. At 100pF, propagation delay increases to ~35ns. For designs requiring both speed and heavier loads, a series resistor (e.g., 22Ω) between OUT and the load is recommended to dampen ringing without significantly degrading edge rate. This load-dependent timing behavior is documented in the MAX998EUT+TG069 datasheet Figure TOC06.
Is the MAX998EUT+TG069 RoHS-compliant and lead-free?
Yes, the "+" suffix in MAX998EUT+TG069 indicates a lead(Pb)-free and RoHS-compliant package per Maxim Integrated's ordering nomenclature. The device uses matte-tin plating and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements. Package compliance is confirmed in the Ordering Information and Package Information sections of the MAX998EUT+TG069 datasheet revision 4 (5/14).
