Product details
Overview
MAX998EUT+TG05 from Maxim Integrated is a single, high-speed, low-power comparator optimized for +2.7V to +5.5V single-supply operation in space-constrained systems. It delivers 20ns propagation delay, 225µA supply current per comparator, and 1nA shutdown current, with rail-to-rail output and ground-sensing inputs - enabling direct interface with CMOS/TTL logic in battery-powered IR receivers and threshold detection circuits.
For engineers reviewing the MAX998EUT+TG05 datasheet, MAX998EUT+TG05 pinout, MAX998EUT+TG05 application, or MAX998EUT+TG05 equivalent, key selection considerations include shutdown functionality (SHDN pin), SOT23-6 package constraints, input common-mode range down to –0.2V, internal 0.5–1.5mV hysteresis, and guaranteed 20ns propagation delay at 50mV overdrive.
Technical Context
The MAX998EUT+TG05 employs a CMOS input stage with a common-mode voltage range of –0.2V to (VCC – 1.2V), allowing inputs to operate below ground while maintaining valid output states. Its push-pull output stage drives rail-to-rail without external pull-ups and tolerates continuous short-circuit faults to either rail.
Internal hysteresis (0.5–1.5mV input-referred) prevents oscillation during slow input transitions, and the SHDN pin enables deterministic low-power mode: driving SHDN low places the output in high-impedance state and reduces ICC to 1nA (typ), with 15µs wake-up time and 5µs shutdown delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 20ns (typ) at 50mV overdrive, CL = 10pF - ensures fast response in timing-critical signal conditioning. |
| Supply Current | 225µA per comparator (typ) at VCC = 5.5V - enables multi-year battery life in portable sensors. |
| Shutdown Current | 1nA (typ) when SHDN = GND - supports ultra-low-power sleep modes in always-on monitoring. |
| Input Common-Mode Range | –0.2V to (VCC – 1.2V) - allows ground-referenced sensing without level-shifting circuitry. |
| Output Type | Rail-to-rail push-pull - directly drives CMOS/TTL logic without pull-up resistors or voltage translation. |
| Hysteresis | 0.5–1.5mV (input-referred) - suppresses noise-induced chatter on slow or noisy input signals. |
| PSRR / CMRR | 63dB / 66dB (min) - maintains stable trip points under supply ripple or common-mode interference. |
Pinout & Package
MAX998EUT+TG05 is housed in a RoHS-compliant 6-pin SOT23-6 package (outline 21-0058), with 1.3mm × 2.2mm footprint and 0.95mm height - suitable for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Primary return path for supply and signal currents; must connect to low-impedance ground plane. |
| 2 - IN− | Inverting input | Differential input node; accepts voltages down to –0.2V and up to (VCC – 1.2V). |
| 3 - IN+ | Noninverting input | Differential input node; same common-mode range as IN−; used for threshold comparison. |
| 4 - OUT | Comparator output | Push-pull rail-to-rail output; high-impedance during shutdown (SHDN = low). |
| 5 - VCC | Positive supply | Single supply input: +2.7V to +5.5V; decoupling capacitor required adjacent to this pin. |
| 6 - SHDN | Shutdown control | Active-low enable; drive ≤0.2×VCC to enter 1nA shutdown; do not leave floating or three-stated. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Functional from +2.7V to +5.5V - eliminates dual-rail supplies in 3V/5V embedded systems. |
| Ground-sensing inputs | Common-mode range extends 200mV below GND - enables direct interfacing with grounded sensors or photodiodes. |
| Integrated hysteresis | 0.5–1.5mV input-referred - removes need for external positive feedback resistors in noise-prone environments. |
| Fast wake-up from shutdown | 15µs (typ) tEN - supports burst-mode sensing with minimal latency penalty after power-down. |
| Rail-to-rail output drive | Drives VOH ≥ VCC – 0.1V and VOL ≤ 0.1V at 2mA - ensures full logic-level compatibility with 1.8V–5V digital interfaces. |
Applications
| IR Receiver Front-End | Low-Voltage Threshold Detector |
|---|---|
|
Use Scenario: Detecting modulated infrared pulses from remote controls or proximity sensors using a photodiode and load resistor. IC Role / Device Role / Timing Role: Comparator acting as high-speed analog front-end, converting photodiode current into clean digital pulses. Use Value: 20ns propagation delay ensures accurate pulse edge capture; rail-to-rail output directly clocks microcontroller GPIO or timer inputs. |
Use Scenario: Monitoring battery voltage in portable medical devices to trigger low-battery alerts before critical discharge. IC Role / Device Role / Timing Role: Precision threshold detector comparing battery voltage against a stable reference. Use Value: Ground-sensing inputs allow direct connection to battery cathode; 1nA shutdown current preserves battery charge during standby. |

|
Use Scenario: Receiving TTL/CMOS-compatible signals across noisy industrial bus lines with marginal signal integrity. IC Role / Device Role / Timing Role: High-speed line receiver providing noise-immune signal regeneration. Use Value: Internal hysteresis rejects sub-mV noise; 225µA quiescent current enables always-on reception in energy-sensitive nodes. |
Use Scenario: Translating between 1.8V logic outputs and 3.3V system inputs in mixed-voltage FPGA or MCU designs. IC Role / Device Role / Timing Role: Voltage-threshold translator using reference bias on IN− and signal on IN+. Use Value: Rail-to-rail output swings fully to 3.3V supply; shutdown pin allows dynamic disable during voltage-domain isolation. |
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 |
|---|---|---|---|
| TLV3501DBVR | No shutdown pin; 4.5ns propagation delay; higher 2.9mA supply current; no ground-sensing inputs (VCM = 0V to VCC – 1.5V). | Better speed but unsuitable for sub-ground sensing or ultra-low-power shutdown use cases. | Select only if <10ns delay is mandatory and shutdown/ground-sense are unnecessary. |
| LMV7215M5X | 25ns propagation delay; 1.1µA shutdown current; rail-to-rail input/output; VCM includes GND but not below. | Lower cost, but lacks true ground-sensing capability and has higher shutdown current than MAX998EUT+TG05. | Prefer where budget constraints outweigh sub-1nA shutdown or –0.2V input requirements. |
Compared with TLV3501DBVR and LMV7215M5X, MAX998EUT+TG05 uniquely combines sub-20ns delay, true ground-sensing inputs, and 1nA shutdown - making it optimal for battery-powered IR receivers and precision low-voltage monitoring where both speed and ultra-low-power operation are non-negotiable.

FAQ
What is the maximum operating temperature range for MAX998EUT+TG05?
The MAX998EUT+TG05 is specified over the industrial temperature range of –40°C to +85°C. All electrical parameters in the datasheet - including propagation delay, supply current, and input offset voltage - are guaranteed across this full range, with typical values measured at +25°C. The device uses CMOS process technology and is qualified for continuous operation within these limits.
Does MAX998EUT+TG05 require external pull-up resistors on its output?
No, MAX998EUT+TG05 does not require external pull-up resistors. Its output is a rail-to-rail push-pull stage capable of sourcing and sinking current to VCC and GND respectively. This design eliminates external components for CMOS/TTL interfacing and ensures fast rise/fall times (1.6ns typ at VCC = 5V), unlike open-drain comparators that mandate pull-ups.
Can the inputs of MAX998EUT+TG05 be driven below ground, and by how much?
Yes, the inputs of MAX998EUT+TG05 can be driven 200mV below ground (down to –0.2V), as confirmed by the common-mode voltage range specification of –0.2V to (VCC – 1.2V). This ground-sensing capability enables direct connection to grounded transducers, photodiodes, or current-sense resistors without level-shifting circuitry - a key differentiator versus standard comparators.
What happens to the output of MAX998EUT+TG05 during shutdown mode?
When SHDN is driven low, MAX998EUT+TG05 enters shutdown mode: the internal comparator core is disabled, supply current drops to 1nA (typ), and the output is placed in a high-impedance (Hi-Z) state. This allows safe sharing of the output node with other devices on a common bus or prevents loading of downstream logic during sleep - critical for system-level power gating.
Is MAX998EUT+TG05 pin-compatible with other members of the MAX976/MAX978/MAX998 family?
No, MAX998EUT+TG05 is not pin-compatible with MAX976 or MAX978. It uses a 6-pin SOT23-6 package with dedicated SHDN and GND pins, whereas MAX976 (dual) uses 8-pin µMAX/SO and MAX978 (quad) uses 16-pin QSOP - each with distinct pinouts, channel counts, and feature sets. Only MAX998 variants (e.g., MAX998EUT+T, MAX998EUT+TG05) share identical pin configuration and footprint.
