Analog Devices Inc./Maxim Integrated MXL1016CN8

Overview

MXL1016CN8 from Maxim Integrated is an ultra-fast precision TTL comparator with complementary outputs, designed for direct interface to TTL logic using either ±5V dual supply or +5V single supply. It delivers 10ns typical propagation delay, 1mV input offset voltage, and includes an output latch (LE) for synchronized sampling in high-speed A/D converters and pulse discriminators.

For engineers reviewing the MXL1016CN8 datasheet, MXL1016CN8 pinout, MXL1016CN8 application, or MXL1016CN8 equivalent, key selection considerations include latch-enable timing (2ns setup/hold), differential propagation delay (4ns), TTL-compatible output drive (2.4V VOH @ 10mA), and operation across 0°C to +70°C industrial temperature range.

Technical Context

The MXL1016CN8 employs a high-gain, low-offset bipolar input stage enabling stable operation with slow-moving inputs without oscillation-critical for zero-crossing detection and current-sense applications in switching regulators. Its latch function synchronizes QOUT/QOUT outputs to external control, eliminating metastability in high-speed sampling circuits.

It supports both dual-supply (±5V) and single-supply (+5V with V− tied to GND) configurations, with input common-mode range spanning –3.75V to +3.5V under dual supply and +1.25V to +3.50V under single supply. CMRR (80–96dB) and PSRR (60–100dB) ensure robust noise immunity in noisy power-conversion environments.

FAQ

What supply voltages does the MXL1016CN8 support?

The MXL1016CN8 operates from either a dual ±5V supply or a single +5V supply with V− tied to GND. Absolute maximum ratings allow +7V on V+ and –7V on V−, but specified performance is guaranteed only within ±5V or +5V/GND configurations. Input common-mode range adjusts accordingly: –3.75V to +3.5V for dual supply, +1.25V to +3.50V for single supply. This flexibility makes MXL1016CN8 suitable for both legacy and modern 5V systems.

Does the MXL1016CN8 require external hysteresis for stable operation?

No, the MXL1016CN8 remains stable with outputs in the active region and has no minimum input slew-rate requirement-unlike many comparators that oscillate with slow-moving inputs. Its internal design eliminates the need for external hysteresis in zero-crossing detection or slowly varying current-sense applications. This behavior is confirmed in the datasheet's stability characterization and distinguishes MXL1016CN8 from general-purpose comparators like LM311.

What is the function of the LE (latch enable) pin on the MXL1016CN8?

The LE pin on the MXL1016CN8 controls synchronous capture of the comparator's output state: when LE is high, QOUT and QOUT are latched and held constant regardless of subsequent input changes. Setup and hold times are both 2ns, enabling precise timing alignment with system clocks. This feature is essential in high-speed sampling circuits and A/D converter interfaces where metastability must be avoided-directly supported by MXL1016CN8's internal latch architecture.

Can the MXL1016CN8 drive standard TTL logic loads directly?

Yes, the MXL1016CN8 provides true complementary TTL outputs: QOUT and QOUT meet standard TTL voltage thresholds-VOH ≥ 2.4V at 10mA source, VOL ≤ 0.4V at 10mA sink-without external pull-ups or level shifters. Its output stage is designed explicitly for direct interface to 74LS and 74F families. This TTL compatibility is a core specification confirmed across temperature and supply variations in the MXL1016CN8 datasheet.

Is the MXL1016CN8 pin-compatible with the MAX913?

Yes, the MAX913 is documented by Maxim as an "improved plug-in replacement" for the MXL1016CN8, sharing identical pinout, package options (including 8-pin DIP), and functional block diagram. Both support LE, complementary TTL outputs, and ±5V/+5V supply operation. However, MAX913 offers faster 8ns tPD and lower 12mA supply current-making MXL1016CN8 and MAX913 electrically and mechanically interchangeable in existing DIP-based designs.
