Product details
Overview
The MAX961ESA+TG52 from Maxim Integrated is a single ultra-high-speed comparator with internal hysteresis, optimized for +3V/+5V single-supply operation. It features 4.5ns propagation delay (5mV overdrive), ±3.5mV input-referred hysteresis, and Beyond-the-Rails™ input range extending 100mV beyond VCC and GND - enabling precise threshold detection in battery-powered GPS receivers and high-speed sampling circuits.
For engineers reviewing the MAX961ESA+TG52 datasheet, MAX961ESA+TG52 pinout, MAX961ESA+TG52 application, or MAX961ESA+TG52 equivalent, key selection criteria include latch-enable functionality, shutdown mode (270μA per comparator), TTL/CMOS-compatible complementary outputs, and SO-8 package compatibility with space-constrained industrial timing and line-receiver designs.
Technical Context
This comparator integrates a current-driven output stage delivering 4mA sink/source capability while maintaining VOH ≤ VCC − 0.52V and VOL ≥ 0.52V across −40°C to +85°C. Its internal 3.5mV hysteresis eliminates external feedback resistors and prevents oscillation near trip points.
The device supports latch-enable (LE) control with 5ns setup/hold time and 10ns latch propagation delay, and enters low-power shutdown (270μA/comparator) when SHDN is high. Input common-mode range spans −0.1V to VCC + 0.1V, and differential input impedance is 8kΩ at 5V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typical at 5mV overdrive - enables sub-5ns decision latency in high-speed data acquisition. |
| Supply Voltage Range | 2.7V to 5.5V - supports direct integration into 3V and 5V logic domains without level shifting. |
| Input Common-Mode Range | −0.1V to VCC + 0.1V - allows detection of signals below GND or above VCC in rail-to-rail sensor interfaces. |
| Output Drive Strength | 4mA sink/source to within 0.52V of rails - directly drives TTL/CMOS loads without pull-up resistors. |
| Hysteresis | 3.5mV input-referred - suppresses noise-induced chatter in threshold-detection applications. |
| Shutdown Current | 270μA per comparator - reduces system power by >94% during idle periods in portable systems. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive-adjacent embedded environments. |
Pinout & Package
MAX961ESA+TG52 is housed in an 8-pin SO (Small Outline) package with standard JEDEC MS-012AC footprint (package code S8-2). The device uses a surface-mount gull-wing lead form compatible with automated reflow assembly.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N.C. | No internal connection - must be left floating or tied to GND per layout best practice to prevent parasitic coupling. |
| 2 | IN− | Inverting input - accepts signals up to 100mV beyond rails; differential input impedance is 8kΩ. |
| 3 | IN+ | Noninverting input - same rail-exceeding range and impedance as IN−; forms precision differential pair. |
| 4 | GND | Analog/digital ground reference - requires low-inductance plane connection for stable high-speed operation. |
| 5 | Q | True TTL/CMOS-compatible output - sinks or sources 4mA while staying within 0.52V of supply rails. |
| 6 | Q̅ | Complementary output - provides inverted logic state simultaneously with Q for differential signaling or latch control. |
| 7 | VCC | Positive supply input - must be decoupled with 0.1μF ceramic capacitor placed adjacent to pin. |
| 8 | SHDN | Active-high shutdown enable - pulls device into 270μA standby mode; high-impedance input requires pull-down for normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast propagation delay | 4.5ns typical ensures minimal timing uncertainty in GPS pulse alignment and zero-crossing detection. |
| Internal hysteresis | 3.5mV eliminates need for external resistor networks - simplifies PCB layout and improves repeatability. |
| Latch-enable function | LE-controlled transparent latch holds comparator output state for synchronized sampling in data converters. |
| Beyond-the-Rails inputs | −0.1V to VCC + 0.1V common-mode range enables direct interfacing with sensors operating outside supply rails. |
| Shutdown mode | 270μA per comparator reduces quiescent power in battery-backed systems without sacrificing wake-up speed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX961EUA-T | Identical electrical specs but in 8-pin μMAX® package (U8-1); 4.10mW/°C derating vs. SO-8's 5.88mW/°C. | Preferred for ultra-dense PCBs where 3.0mm × 3.0mm footprint is critical; thermal performance differs slightly. | Select MAX961EUA-T only when board area is constrained and thermal margin permits lower power dissipation rating. |
| TLV3501CD | 4.5ns delay, 2.7–5.5V supply, but no internal hysteresis or latch-enable; 3.5mA supply current vs. 5–11mA. | Suitable for cost-sensitive, non-latching applications where external hysteresis can be added; lacks LE/SHDN control pins. | Choose TLV3501CD when latch and shutdown functions are unnecessary and BOM cost reduction is prioritized. |
Compared with MAX961ESA+TG52, MAX961EUA-T offers identical functionality in a smaller package but reduced thermal headroom, while TLV3501CD trades integrated features for lower cost and power - making MAX961ESA+TG52 optimal for latch-critical, thermally robust SO-8 designs.

FAQ
What is the operating temperature range for MAX961ESA+TG52?
The MAX961ESA+TG52 is specified for operation from −40°C to +85°C. This E-grade qualification covers full electrical performance across the industrial temperature range, including propagation delay, hysteresis, and output drive strength - all guaranteed per the datasheet's TMIN to TMAX limits. The MAX961ESA+TG52 does not support the extended +125°C range offered by the MAX999AAUK variant.
Does MAX961ESA+TG52 require external hysteresis resistors?
No, the MAX961ESA+TG52 includes 3.5mV of internal input-referred hysteresis, eliminating the need for external positive-feedback resistors. This fixed hysteresis stabilizes switching behavior near trip points and prevents noise-induced oscillation - a key advantage over general-purpose comparators like LM393 that require discrete hysteresis networks.
How does the latch-enable feature work on MAX961ESA+TG52?
The MAX961ESA+TG52 uses pin 8 (SHDN) for shutdown and has no dedicated LE pin; its latch-enable function is implemented via the complementary outputs Q and Q̅ used in external SR-latch configurations. True integrated latch control (with LE pin) is available only on MAX961/MAX963 in μMAX or SO packages with explicit LE pin assignment - not on the SO-8 MAX961ESA+TG52 variant.
What is the maximum capacitive load the MAX961ESA+TG52 can drive?
The MAX961ESA+TG52 is characterized with a 5pF load, and propagation delay increases linearly with capacitance - e.g., rising from 4.5ns at 5pF to ~6.5ns at 50pF (per typical curves). For loads exceeding 20pF, slew rate degradation becomes significant; use local buffering or reduce trace capacitance to maintain sub-5ns timing integrity in high-speed sampling circuits.
Is MAX961ESA+TG52 RoHS-compliant and lead-free?
Yes, the "+" suffix in MAX961ESA+TG52 indicates a lead(Pb)-free and RoHS-compliant package per Maxim Integrated's labeling convention. The SO-8 package (S8-2) uses matte tin plating and meets JEDEC J-STD-609 Category 1 moisture sensitivity level (MSL-1), supporting standard Pb-free reflow profiles without special handling.
