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 timing-critical signal discrimination in mixed-signal systems. It delivers 7ns typical propagation delay (at 5mV overdrive), 9mW per comparator power consumption at +5V supply, and supports separate analog (±5V or +5V to +10V) and digital (+5V) supplies. It is used in high-speed A/D converters, line receivers, and PWM circuits where fast, low-power threshold detection with output hold capability is required.

For engineers reviewing the MAX9202EUD-T datasheet, MAX9202EUD-T pinout, MAX9202EUD-T application, or MAX9202EUD-T equivalent, this page provides verified functional specifications, TSSOP-14 package mapping, latch-enabled dual-comparator behavior, input common-mode range extending to VEE, and real-world selection guidance against comparable comparators.

Technical Context

The MAX9202EUD-T implements two independent high-gain bipolar comparators with active internal TTL pullups and dedicated latch control inputs (LATCHA/LATCHB) that freeze output states on logic-low assertion. Its analog input stage accepts common-mode voltages from VEE − 0.1V to VCC − 2.25V, enabling ground-sensing operation when VEE = GND.

Timing performance is characterized under 15pF load and 2mA drive: tPD+ and tPD− are both 7ns typ (12ns max over temperature), with latch-disable delays of 10ns and setup/hold times of 2ns/1ns respectively - confirming deterministic edge-aligned sampling suitable for synchronous data capture.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency supported by the MAX9202EUD-T?

The MAX9202EUD-T does not specify a maximum operating frequency as a standalone parameter, but its 7ns typical propagation delay and 2.5ns max inter-channel skew enable reliable operation in systems with effective sampling rates exceeding 100MHz. For example, in a latch-synchronized A/D converter front-end, the MAX9202EUD-T supports decision windows down to 10ns, allowing accurate digitization of signals with rise times <5ns. Real-world performance depends on layout, load capacitance, and input slew rate - all detailed in the MAX9202EUD-T typical operating characteristics graphs.

Does the MAX9202EUD-T require external pullup resistors on its outputs?

No, the MAX9202EUD-T features active internal TTL pullups on both OUTA and OUTB pins, eliminating the need for external pullup resistors. Each output can directly drive up to four LS-TTL loads or ten 74HC inputs while maintaining VOH ≥ 3.0V at 1mA source current and VOL ≤ 0.4V at 8mA sink current. This integrated design simplifies PCB layout, reduces component count, and ensures consistent rise/fall times - critical for high-speed signal integrity in the MAX9202EUD-T's target applications.

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

Yes, the MAX9202EUD-T supports single +5V operation: connect VCC = +5V, VEE = GND, and VDD = +5V. In this configuration, the analog input common-mode range extends from GND to +2.75V, enabling ground-referenced sensing without level shifters. The device maintains full 7ns propagation delay and latch functionality. However, note that the analog supply range is limited to +5V in single-supply mode - the +5V to +10V range applies only when VEE is grounded and VCC is elevated above +5V.

What is the purpose of the N.C. pins (6 and 13) on the MAX9202EUD-T?

Pins 6 and 13 on the MAX9202EUD-T are designated N.C. (No Connection) - they have no internal bond wire or circuit connection and must remain unconnected in the PCB layout. These pins are not intended for grounding, thermal relief, or signal routing. Leaving them floating is electrically safe; however, best practice is to omit copper pads or traces on those pins to prevent accidental shorts or solder bridging. Their presence accommodates die size and leadframe design constraints in the TSSOP-14 package, not functional circuitry.

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

During power-up, the MAX9202EUD-T latch inputs (LATCHA/LATCHB) default to high-impedance until VDD reaches valid TTL logic thresholds (~1.4V). Once VDD stabilizes, the latches enter transparent mode (output follows input) if LATCH_ pins are held high, or hold last state if pulled low. To ensure deterministic startup, tie LATCHA and LATCHB to VDD through 10kΩ resistors unless actively driven - this guarantees transparent operation at power-on and avoids metastability. The MAX9202EUD-T datasheet specifies no power-up reset or initialization sequence; behavior is fully determined by external latch control voltage at the moment VDD crosses 1.4V.
