Analog Devices Inc./Maxim Integrated MAX9010EXT-T

Overview

MAX9010EXT-T from Maxim Integrated is a single, high-speed, precision TTL comparator operating from a 4.5V to 5.5V single supply. It features 5ns typical propagation delay, 900µA quiescent current, and a rail-to-rail input range extending 200mV below ground-ideal for low-power, high-speed zero-crossing detection and signal squaring in space-constrained industrial timing circuits.

For engineers reviewing the MAX9010EXT-T datasheet, MAX9010EXT-T pinout, MAX9010EXT-T application, or MAX9010EXT-T equivalent, this device delivers verified sub-7mV input offset voltage, stable operation with slow-moving inputs, no output phase reversal on overdrive, and guaranteed -40°C to +85°C performance in the 6-pin SC70 package.

Technical Context

The MAX9010EXT-T employs a fully differential bipolar input stage with no built-in hysteresis, enabling high-resolution comparison without resolution loss. Its linear-region stability eliminates oscillation even at near-zero differential input voltages, removing the need for external hysteresis networks.

It uses TTL-compatible output logic with defined VOL (0.5V max at 4mA sink) and VOH (2.4V min at 4mA source), and supports direct interfacing with 5V logic families. The device requires no minimum input slew rate and maintains correct decision-making as long as at least one input remains within the -0.2V to (VCC – 1.9V) common-mode range.

Key Specifications

Pinout & Package

MAX9010EXT-T is housed in a 6-pin SC70 package (2.0mm × 1.25mm, 0.5mm pitch), optimized for ultra-compact PCB layouts. Thermal resistance θ_JA is 322°C/W; recommended 0.1µF ceramic bypass capacitor must be placed adjacent to V_CC.

FAQ

What is the maximum input overdrive voltage the MAX9010EXT-T can tolerate without damage?

The MAX9010EXT-T tolerates analog input voltages from -0.3V to (V_CC + 0.3V) - meaning up to +5.8V on a 5.5V supply. This absolute rating applies to IN+ and IN- individually. Damage is avoided as long as neither exceeds these limits, even if both inputs are simultaneously outside the specified common-mode range (-0.2V to V_CC – 1.9V). The MAX9010EXT-T remains functional provided at least one input stays within that range.

Does the MAX9010EXT-T require external hysteresis for stable operation?

No - the MAX9010EXT-T does not require external hysteresis. Its unique bipolar architecture prevents oscillation in the linear region, even with slow-moving or low-overdrive inputs. Adding hysteresis degrades resolution by introducing an indeterminate switching band and is explicitly discouraged in the datasheet. The MAX9010EXT-T achieves stable, jitter-free output transitions without any external components.

Can the MAX9010EXT-T operate from a 3.3V supply?

No - the MAX9010EXT-T is specified only for 4.5V to 5.5V operation. Electrical characteristics including propagation delay, output drive strength, and input offset voltage are guaranteed only within this range. At 3.3V, the device may fail to meet TTL output thresholds (VOH ≥ 2.4V, VOL ≤ 0.6V), exhibit increased propagation delay, or cease functioning entirely. For 3.3V systems, consider alternatives like the TLV3501.

What is the purpose of connecting both Pin 5 and Pin 6 to V_CC on the MAX9010EXT-T?

Pins 5 and 6 of the MAX9010EXT-T are internally bonded to the same V_CC node and must both be connected to the supply rail. This dual-pin configuration reduces effective bond wire inductance and improves high-frequency PSRR. Leaving either pin unconnected increases supply impedance, causing output instability, increased propagation delay variation, and potential failure to meet the 5ns specification under dynamic load conditions.

How does the MAX9010EXT-T handle input signals where both IN+ and IN- go below ground simultaneously?

When both IN+ and IN- fall below -0.2V (i.e., outside the specified common-mode range), the MAX9010EXT-T output state becomes indeterminate - it may settle high, low, or oscillate unpredictably. However, the device sustains no damage. Correct logic decisions are guaranteed only when at least one input remains within -0.2V to (V_CC – 1.9V). For robust sub-ground operation, ensure differential swing keeps one input inside this window.
