Analog Devices Inc./Maxim Integrated MXL1016CS8

Overview

MXL1016CS8 from Maxim Integrated is an ultra-fast precision TTL comparator with complementary outputs, 10ns typical propagation delay, ±5V or +5V single-supply operation, and integrated output latch. It interfaces directly to TTL logic in high-speed sampling circuits, zero-crossing detection, and switching regulator current sensing.

For engineers reviewing the MXL1016CS8 datasheet, MXL1016CS8 pinout, MXL1016CS8 application, or MXL1016CS8 equivalent, key selection criteria include latch-enable timing (2ns setup/hold), input offset voltage (1mV typ), CMRR (96dB), PSRR (100dB), and SO-8 package compatibility with industrial-grade temperature range (0°C to +70°C).

Technical Context

The MXL1016CS8 employs a high-gain, low-offset bipolar input stage enabling stable operation with slow-moving inputs and no minimum slew-rate requirement. Its complementary TTL outputs drive standard logic loads without external level-shifting, and the LE pin provides synchronous latching of QOUT/QOUT states.

It operates across dual ±5V or single +5V supplies, with V− tied to GND in single-supply mode. Input common-mode range spans −3.75V to +3.5V (dual) or +1.25V to +3.50V (single), and output stages deliver VOH ≥ 2.4V at 10mA sink while maintaining VOL ≤ 0.4V.

FAQ

What supply configurations does the MXL1016CS8 support?

The MXL1016CS8 operates from either a dual ±5V supply (with V+ = +5V, V− = −5V) or a single +5V supply (with V− tied to GND). Both configurations maintain full specification compliance, including 10ns propagation delay and TTL output levels. The input common-mode range adjusts accordingly: −3.75V to +3.5V for dual supply, +1.25V to +3.50V for single supply. This flexibility simplifies integration into both legacy and modern power architectures.

Does the MXL1016CS8 require external hysteresis for stable operation?

No, the MXL1016CS8 remains stable with outputs in the active region and has no minimum input slew-rate requirement, eliminating the need for external hysteresis in most applications. Its internal design prevents oscillation during slow input transitions-critical for zero-crossing detection and low-frequency signal monitoring. Hysteresis should only be added if system-level noise immunity exceeds the device's inherent rejection (CMRR = 96dB, PSRR = 100dB).

What is the function of the LE (latch enable) pin on the MXL1016CS8?

The LE pin on the MXL1016CS8 is an active-high control that synchronously latches the current states of QOUT and QOUT. When LE is high, the outputs hold their values regardless of subsequent input changes; when LE returns low, outputs resume real-time comparison. This enables precise timing capture in sampled-data systems. Setup and hold times are both 2ns, allowing reliable use with 500MHz clocks.

Can the MXL1016CS8 drive standard TTL logic directly?

Yes, the MXL1016CS8 features true complementary TTL outputs: QOUT sources ≥2.4V at 10mA load and sinks ≤0.4V at 10mA, fully meeting 74LS logic thresholds. No level-shifting or buffering is required. The outputs are designed for direct fan-out to up to 10 LS-TTL loads, making it ideal for interfacing with legacy digital systems and FPGA input banks configured for TTL voltage standards.

Is the MXL1016CS8 pin-compatible with the MAX913?

Yes, the MXL1016CS8 is pin-compatible with the MAX913 in the SO-8 package: all eight pins share identical functions, electrical behavior, and physical layout. The MAX913 is explicitly documented by Maxim as an "improved plug-in replacement" with lower propagation delay (5ns vs. 10ns) and reduced input offset (0.5mV vs. 1mV). No PCB redesign is needed when upgrading from MXL1016CS8 to MAX913.
