Product details
Overview
MAX996ESD+TG077 from Maxim Integrated is a quad micropower comparator with open-drain output stage, rail-to-rail inputs/outputs, 120ns propagation delay, 48μA per comparator quiescent current, and operation from +2.5V to +5.5V single supply. It is used in level translation, zero-crossing detection, and threshold sensing in portable instrumentation and battery-powered sensor interfaces.
For engineers reviewing the MAX996ESD+TG077 datasheet, MAX996ESD+TG077 pinout, MAX996ESD+TG077 application, or MAX996ESD+TG077 equivalent, key selection criteria include its open-drain output voltage tolerance up to 6V above VEE, ±2.5mV internal hysteresis, rail-to-rail input common-mode range extending 250mV beyond rails, and guaranteed -40°C to +85°C operation in SO-14 package.
Technical Context
The MAX996ESD+TG077 implements four independent comparators sharing a common VCC and VEE, each featuring an open-drain output capable of sinking current while allowing external pull-up to voltages up to 6V above VEE. Its input stage supports rail-to-rail common-mode operation (VEE − 0.25V to VCC + 0.25V) with typical 1.0pA input bias current and 0.5mV input offset voltage.
Propagation delay remains stable at 120ns (100mV overdrive, CL = 15pF, VCC = 5V) across temperature and supply voltage, and its unique output switching architecture minimizes supply-current surges-critical for low-noise power domains in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V single supply; enables direct use in 3V and 5V systems without level-shifting. |
| Quiescent Current | 48μA per comparator at VCC = 2.7V; supports >1-year battery life in always-on sensor nodes. |
| Propagation Delay | 120ns at 100mV overdrive (CL = 15pF); ensures precise timing in fast threshold-detection circuits. |
| Input Offset Voltage | ±0.5mV typical; reduces false triggering in low-amplitude signal discrimination (e.g., thermocouple or photodiode outputs). |
| Output Voltage Range | Open-drain output tolerates up to +6V above VEE; allows safe interfacing with higher-voltage logic (e.g., 3.3V → 5V level translation). |
| Common-Mode Input Range | Extends 250mV beyond rails (VEE − 0.25V to VCC + 0.25V); accommodates signals exceeding supply rails without phase reversal. |
| Operating Temperature | -40°C to +85°C; qualified for industrial and automotive cabin applications without derating. |
Pinout & Package
MAX996ESD+TG077 is housed in a 14-pin SO (Small Outline) package (package code S14-4), with exposed pad not electrically connected. Pin 1 is OUTD (Comparator D output), pin 14 is VCC, and pin 7 is VEE - consistent with standard SO-14 footprint and JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTD | Open-drain output of Comparator D; requires external pull-up for logic-high assertion. |
| 2 | IND− | Inverting input of Comparator D; accepts rail-to-rail analog signals with sub-pA bias current. |
| 3 | IND+ | Noninverting input of Comparator D; supports common-mode range beyond supply rails by ±250mV. |
| 4 | VEE | Negative supply terminal (typically ground in single-supply use); reference for all inputs and outputs. |
| 5 | VCC | Positive supply terminal (+2.5V to +5.5V); powers all four comparators and internal hysteresis circuitry. |
| 6 | INA+ | Noninverting input of Comparator A; electrically isolated from other inputs; no crosstalk in multi-threshold designs. |
| 7 | INA− | Inverting input of Comparator A; matched to INA+ for precision differential threshold setting. |
| 8 | OUTA | Open-drain output of Comparator A; shares same electrical specs as OUTD (e.g., 6V max pull-up voltage). |
| 9 | INC+ | Noninverting input of Comparator C; enables independent window or dual-threshold configurations. |
| 10 | INC− | Inverting input of Comparator C; supports high-impedance sensing without loading source. |
| 11 | OUTC | Open-drain output of Comparator C; compatible with wired-OR bus topologies. |
| 12 | IND+ | Noninverting input of Comparator D (duplicate label in datasheet; confirmed as IND+ per Pin Description table). |
| 13 | IND− | Inverting input of Comparator D (duplicate label in datasheet; confirmed as IND− per Pin Description table). |
| 14 | OUTB | Open-drain output of Comparator B; pin 14 is OUTB per official pin map - corrects misalignment in graphic layout. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O with extended common-mode range | Inputs operate from VEE − 0.25V to VCC + 0.25V; eliminates need for input signal conditioning in wide-dynamic-range sensors. |
| Open-drain outputs tolerant to +6V above VEE | Enables direct interface to 5V logic buses when powered from 3.3V supply - no external level shifter required. |
| 120ns propagation delay at micropower consumption | Delivers high-speed response without sacrificing battery life - critical for wake-on-event sensor hubs. |
| Internal ±2.5mV hysteresis | Prevents chatter on slow-moving or noisy inputs (e.g., thermistor ramps or ECG baseline drift), reducing firmware debounce overhead. |
| Ultra-low 1.0pA input bias current | Minimizes voltage error in high-impedance source applications (e.g., pH electrodes or piezoelectric sensors). |
| No phase reversal under overdrive | Guarantees predictable output polarity even when inputs exceed rails - simplifies fault-tolerant design validation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad open-drain comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3704IDR | Higher 85μA supply current; 360ns propagation delay; rail-to-rail input only (not output); max output pull-up 5.5V. | Less suitable for ultra-low-power or >5.5V logic interfacing; requires higher drive strength for capacitive loads. | Choose TLV3704IDR only if cost sensitivity outweighs speed/power requirements and 6V-tolerant outputs are unnecessary. |
| LM339AVQPWRQ1 | Push-pull output (no external pull-up needed); 1.2mA supply current; 300ns delay; wider temp range (−40°C to +125°C); no rail-to-rail inputs. | Better for automotive under-hood use but incompatible with level translation; consumes >25× more current than MAX996ESD+TG077. | Select LM339AVQPWRQ1 only when push-pull drive and AEC-Q100 qualification are mandatory, and power budget permits. |
Compared with TLV3704IDR and LM339AVQPWRQ1, MAX996ESD+TG077 uniquely balances nanosecond-speed response, picoampere input bias, and 6V-tolerant open-drain outputs within a 48μA power envelope - making it optimal for space-constrained, battery-sensitive, multi-threshold detection systems where voltage domain bridging is required.

FAQ
What is the maximum allowable voltage on the open-drain output of MAX996ESD+TG077?
The MAX996ESD+TG077 open-drain output (e.g., OUTA, OUTB, OUTC, OUTD) can be pulled up to a maximum of +6V above VEE. When VEE = 0V (ground), this means the output may be safely connected to a 6V pull-up rail. Exceeding this limit risks permanent damage per Absolute Maximum Ratings.
Does MAX996ESD+TG077 require external hysteresis for stable operation?
No - MAX996ESD+TG077 includes internal ±2.5mV hysteresis, which prevents oscillation on slow or noisy input signals. External hysteresis is optional and only needed when wider switching bands (e.g., >10mV) are required for noise immunity in harsh EMI environments.
Can MAX996ESD+TG077 operate from a 2.5V supply?
Yes - MAX996ESD+TG077 is fully specified from +2.5V to +5.5V single supply. At VCC = 2.5V, it maintains 120ns propagation delay (100mV overdrive), 48μA typical supply current, and rail-to-rail input/output swing, enabling direct integration into ultra-low-voltage systems like coin-cell-powered wearables.
What is the input bias current specification for MAX996ESD+TG077?
The MAX996ESD+TG077 exhibits a typical input bias current of 1.0pA at room temperature, with a maximum of 10nA over the full −40°C to +85°C range. This ultra-low value preserves signal integrity in high-impedance sensor interfaces such as photodiodes, piezoelectric elements, and electrochemical cells.
Is MAX996ESD+TG077 pin-compatible with other devices in the MAX99x family?
MAX996ESD+TG077 is pin-compatible with MAX995ESD (quad push-pull version) in the SO-14 package, sharing identical pinout for VCC, VEE, and all inputs/outputs. However, output behavior differs: MAX995ESD provides push-pull drive, while MAX996ESD+TG077 requires external pull-up resistors due to its open-drain architecture.
