onsemi MC10H210FN

Overview

MC10H210FN from ON Semiconductor is a dual 3-input/3-output MECL 10K-compatible OR gate in a 20-lead PLLC package, delivering 1.0 ns typical propagation delay, −1.95 V to −0.735 V output voltage swing, and 160 mW typical power dissipation. It drives up to six transmission lines simultaneously and supports wire-ORing of multiple logic levels for clock distribution with minimized skew.

For engineers reviewing the MC10H210FN datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, thermal limits, package dimensions, and substitution guidance aligned with ON Semiconductor's Rev. 7 datasheet (MC10H210/D, Feb 2006).

Technical Context

The MC10H210FN implements two independent 3-input OR gates, each with three buffered outputs-enabling fanout to six transmission lines without external buffering. Its voltage-compensated design maintains stable VIH/VIL thresholds across temperature (0°C to +75°C) and supply variation (VEE = −5.2 V ±5%).

All inputs and outputs are compatible with MECL 10K logic families, with guaranteed noise margin of 150 mV over full operating range. Outputs are terminated to −2.0 V via 50 Ω resistors per AC test conditions, supporting high-speed signal integrity in clock tree and data path applications.

FAQ

What is the maximum operating temperature for the MC10H210FN?

The MC10H210FN is specified for an operating temperature range of 0°C to +75°C. This limit is defined in Table 1 of the official datasheet (Rev. 7, Feb 2006) and applies under standard airflow conditions (>500 lfpm). Exceeding +75°C may degrade propagation delay stability and noise margin performance. The MC10H210FN does not support extended temperature grades unless replaced by the MC100H210FN variant.

Is the MC10H210FN pin-compatible with other MECL OR gate devices?

The MC10H210FN uses a unique 20-lead PLLC package (Case 775) and is not pin-compatible with PDIP-16 or SOIC-16 MECL OR gates like the MC10H108P or MC10H116. Pin assignments differ significantly-especially VCC1/VCC2/VEE placement and output grouping. Direct PCB replacement requires layout revision. Always verify pin mapping using the "Pin Conversion Tables" referenced in the ON Semiconductor MECL Data Book (DL122/D).

What termination is required for MC10H210FN outputs to meet AC specifications?

To meet the AC parameter specifications (tpd, tr, tf) in Table 3, each MC10H210FN output must be terminated with a 50 Ω resistor to −2.0 V. This condition is explicitly stated in Note 1 of the datasheet and is mandatory for guaranteed timing performance. Failure to apply proper termination results in signal reflection, degraded edge rates, and increased propagation delay variation.

Does the MC10H210FN support Pb-free soldering?

Yes-the MC10H210FN is available in both standard and Pb-free versions. The Pb-free variant is designated MC10H210FNG (rail) or MC10H210FNR2G (tape & reel), as confirmed in the Ordering Information table on page 3 of the datasheet. ON Semiconductor's Pb-free strategy complies with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and supports standard reflow profiles per their Soldering and Mounting Techniques Reference Manual (SOLDERRM/D).

How does the MC10H210FN achieve improved noise margin?

The MC10H210FN achieves a guaranteed 150 mV noise margin over its full operating voltage and temperature range through voltage-compensated input circuitry that dynamically adjusts VIH and VIL thresholds relative to VEE drift. This design prevents logic misinterpretation during supply ripple or thermal-induced threshold shift-critical in high-density ECL systems where crosstalk and ground bounce are prevalent. The value is measured differentially between VOH–VOL and VIH–VIL windows.
