Analog Devices Inc./Maxim Integrated MAX9202EUD+T

Overview

MAX9202EUD+T from Maxim Integrated is a dual high-speed voltage comparator with TTL-compatible outputs and latch inputs, designed for precision signal discrimination in timing-critical circuits. It delivers 7ns typical propagation delay at 5mV overdrive, consumes only 4.0mA analog supply current (ICC), supports ±5V or +5V-to-+10V analog supplies with VEE grounded, and operates across –40°C to +85°C in a 14-pin TSSOP package - ideal for high-speed A/D converter front-ends and line receivers.

For engineers reviewing the MAX9202EUD+T datasheet, MAX9202EUD+T pinout, MAX9202EUD+T application, or MAX9202EUD+T equivalent, this page provides verified electrical parameters, latch timing constraints (tS = 2ns, tN = 1ns), dual-channel input/output mapping, and real-world design context for fast data sampling and signal restoration circuits.

Technical Context

The MAX9202EUD+T implements two independent high-gain bipolar comparators with active internal TTL pullups and dedicated latch control per channel. Its analog input common-mode range extends to the negative rail (VEE), enabling ground-sensing operation with single-supply configurations (+5V VCC, VEE = GND).

Latch functionality is synchronous: driving LATCHA/LATCHB low freezes the corresponding comparator output state; the latch disable-to-output delays are tPD+(D) = 10ns and tPD–(D) = 10ns. Propagation delay matching between channels is tightly controlled (∆tPD ≤ 2.5ns over temperature), critical for differential timing applications.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable analog supply voltage for MAX9202EUD+T?

The MAX9202EUD+T supports an analog supply voltage range of VCC – VEE = +4.75V to +10.5V. When operated with VEE = GND (single supply), VCC may be up to +10.5V. Absolute maximum rating for VCC – VEE is +12V, but sustained operation above +10.5V is not specified and may compromise parametric performance or reliability. Always refer to the Electrical Characteristics table for guaranteed operation.

Does MAX9202EUD+T require separate analog and digital ground planes?

While MAX9202EUD+T does not mandate separate ground planes, its architecture benefits significantly from them. The device uses distinct GND (digital) and VEE (analog substrate) pins. For optimal noise immunity in high-speed applications, connect GND to the digital ground plane and VEE to the analog ground plane - then join both at a single point near the device's power entry. This prevents digital switching noise from modulating analog input thresholds.

Can MAX9202EUD+T operate from a single +5V supply?

Yes, MAX9202EUD+T can operate from a single +5V supply: configure VCC = +5V, VEE = GND, and VDD = +5V. In this mode, the input common-mode range extends from GND to +2.75V, supporting ground-referenced signals. Output VOH remains ≥3.0V and VOL ≤0.4V under load, ensuring robust TTL compatibility without level shifters.

What is the function of the N.C. pins on MAX9202EUD+T?

Pins 6 and 13 of MAX9202EUD+T are marked N.C. (No Connection) - they have no internal bond wire or circuit connection. These pins may be left floating, tied to GND for mechanical reinforcement, or used as thermal pads if the PCB layout includes exposed copper under the package. They must never be connected to active signals or supply rails, as doing so could cause unpredictable behavior or damage.

How does the latch feature of MAX9202EUD+T behave during power-up?

At power-up, the latch inputs (Pins 4 and 11) default to high impedance until VDD reaches valid logic levels. Once VDD stabilizes, the latch inputs become active - and since they are active-low, the comparators remain transparent (non-latched) until driven low. To ensure deterministic startup, apply a known logic state to LATCHA/LATCHB after VDD regulation is complete; avoid floating these inputs during system initialization to prevent metastable output states in MAX9202EUD+T.
