Analog Devices Inc./Maxim Integrated MXL1116CN8

Overview

MXL1116CN8 from Maxim Integrated is an ultra-fast, complementary-output TTL comparator with 12ns typical propagation delay, designed for direct interface to TTL logic using either ±5V dual supply or +5V single supply. It features input common-mode range extending to the negative supply, input overvoltage tolerance up to +15V (beyond V+), and an output latch enable (LE) pin. It is used in high-speed sampling circuits and zero-crossing detectors.

For engineers reviewing the MXL1116CN8 datasheet, MXL1116CN8 pinout, MXL1116CN8 application, or MXL1116CN8 equivalent, key selection considerations include latch timing (tSU = 2ns, tH = 2ns), input overvoltage resilience (+15V absolute max on inputs), complementary TTL outputs with VOH ≥2.7V/ISOURCE = 1mA, and operation across 0°C to +70°C in 8-pin plastic DIP.

Technical Context

The MXL1116CN8 employs a high-gain, low-offset bipolar comparator core optimized for speed without sacrificing precision-achieving 12ns typical propagation delay while maintaining ±2mV input offset voltage and 90dB CMRR. Its input stage allows operation with VCM as low as –5V (dual supply) or 0V (single supply), and tolerates input voltages up to +15V regardless of supply configuration.

It integrates a transparent latch controlled by LE: when LE is high, QOUT and QOUT hold their last valid state; when LE is low, outputs respond dynamically to input transitions. The latch eliminates metastability issues in high-speed trigger applications where asynchronous sampling occurs near signal thresholds.

Key Specifications

Pinout & Package

MXL1116CN8 is housed in an 8-pin plastic DIP (0.300" wide) package per JEDEC MS-001, with through-hole mounting and industry-standard lead spacing (e = 2.54mm).

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed TTL comparator applications.

Compared with MXL1116CN8, MAX913 offers lower propagation delay and offset voltage in identical packaging, making it a preferred upgrade; LM360N lacks latch support and TTL compatibility, limiting use to non-latched, high-voltage analog comparator roles where speed is secondary.

FAQ

What is the maximum input voltage the MXL1116CN8 can tolerate without damage?

The MXL1116CN8 allows input voltages up to +15V on either IN+ or IN–, independent of supply configuration - a key differentiator from the MXL1016. This rating holds under all operating conditions and is specified in the Absolute Maximum Ratings table. Exceeding +15V risks permanent damage. The MXL1116CN8 maintains functionality within this limit while preserving 12ns propagation delay and latch integrity.

Does the MXL1116CN8 support single-supply operation, and what is the valid input common-mode range in that mode?

Yes, the MXL1116CN8 operates from a single +5V supply with V– connected to GND. In this configuration, the input common-mode range is 0V to +2.5V (VCM = 0V to V+ – 2.5V), as confirmed in the MXL1116 electrical characteristics table. This enables direct interfacing with 0–3.3V or 0–2.5V sensor outputs without level-shifting circuitry. The MXL1116CN8 retains its 12ns propagation delay and latch functionality in single-supply mode.

What is the function of Pin 5 (LE) on the MXL1116CN8, and how does it affect output behavior?

Pin 5 (LE) is the Latch Enable input: when LE is high, the MXL1116CN8 latches and holds the current states of QOUT and QOUT; when LE is low, outputs respond immediately to input changes. The latch has 2ns setup and 2ns hold time requirements. This feature allows the MXL1116CN8 to capture transient events synchronously - for example, freezing comparator output at a precise clock edge. The MXL1116CN8 uses internal positive-feedback latching, not external storage elements.

How does the MXL1116CN8 differ from the MXL1016CN8 in terms of input voltage range and propagation delay?

The MXL1116CN8 provides extended input voltage tolerance (+15V max vs. ±5V for MXL1016CN8) and a slightly longer typical propagation delay (12ns vs. 10ns). Its input common-mode range reaches the negative supply rail in dual-supply mode, whereas MXL1016CN8 is limited to ±3.75V. Both share identical pinout, latch function, and TTL output drive capability. The MXL1116CN8 is selected when overvoltage resilience is prioritized over marginal speed gain.

Is the MXL1116CN8 RoHS-compliant and halogen-free?

Yes, the MXL1116CN8 is RoHS-compliant and halogen-free per Maxim Integrated's product change notices and packaging specifications dated 2012 onward. The plastic DIP package (JEDEC MS-001) uses lead-free matte tin lead finish and complies with EU Directive 2011/65/EU. No exemptions apply. The MXL1116CN8 meets IPC/JEDEC J-STD-609A Class 1 for halogen content (<900ppm Cl + Br), verified via material declaration and supplier certification.
