onsemi MC10H210MG

Overview

MC10H210MG from ON Semiconductor is a dual 3-input/3-output MECL 10H-compatible OR gate optimized for low-skew clock distribution and wire-OR logic in high-speed digital systems. It delivers typical propagation delay of 1.0 ns, 160 mW power dissipation, and operates across 0°C to +75°C with VEE = −5.2 V ±5%.

For engineers reviewing the MC10H210MG datasheet, pinout, applications, or equivalent options, this device is selected for timing-critical ECL logic fanout, multi-level gating consolidation, and transmission-line-driven clock trees where sub-1.6 ns max tpd and matched rise/fall times (0.75–2.0 ns) are required.

Technical Context

The MC10H210MG implements two independent 3-input OR gates, each with three complementary outputs (AOUT/AOUT/AOUT and BOUT/BOUT/BOUT), enabling simultaneous drive of up to six 50 Ω transmission lines terminated to −2.0 V. Its voltage-compensated design maintains stable VIH/VIL thresholds across temperature and supply variation.

Designed for MECL 10H™ system compatibility, it features improved noise margin (150 mV) and supports operation with VEE = −5.2 V ±5%, while drawing 38–42 mA supply current. Outputs meet ECL logic levels: VOH = −0.92 to −0.735 V, VOL = −1.95 to −1.60 V at 75°C.

Key Specifications

Pinout & Package

MC10H210MG uses a 16-pin SOEIAJ (Small Outline Integrated Circuit, JEDEC standard) plastic package (Case 966), Pb-free, with gull-wing leads. Pin 1 is marked by notch or dot; pin numbering follows standard counter-clockwise convention from top-left corner.

FAQ

What is the recommended termination for MC10H210MG outputs?

Each MC10H210MG output must be terminated with a 50 Ω resistor to −2.0 V, as specified in the datasheet's AC parameter test conditions. This termination ensures impedance matching to standard 50 Ω transmission lines, minimizes reflections, and guarantees the published propagation delay (0.6–1.7 ns) and rise/fall time (0.75–2.0 ns) performance. Failure to terminate correctly results in signal integrity degradation and timing violations.

Does MC10H210MG support mixed-voltage operation between its two OR gates?

No. The MC10H210MG does not support independent supply domains. Both VCC1 (Pins 1, 15) and VCC2 (Pin 16) must be connected to ground (0 V), and VEE (Pin 8) must be a common −5.2 V ±5% supply for the entire device. There is no provision for separate biasing of Gate A and Gate B sections - they share the same VEE reference and internal bias network.

Can MC10H210MG be used with modern 3.3 V or 5 V logic families?

No. The MC10H210MG is strictly an MECL 10H device requiring VEE = −5.2 V and producing ECL-compatible output voltages (VOH ≈ −0.8 V, VOL ≈ −1.8 V). It is incompatible with TTL, CMOS, or LVDS logic families without level-shifting circuitry. Direct interfacing to 3.3 V or 5 V systems will cause functional failure or damage due to voltage domain mismatch.

What is the maximum output load capacitance supported by MC10H210MG?

The MC10H210MG is characterized for driving 50 Ω resistive loads terminated to −2.0 V. While not explicitly rated for capacitive loading, layout best practices limit total output node capacitance to ≤2 pF to maintain specified rise/fall times (0.75–2.0 ns) and avoid excessive delay degradation. Exceeding this increases tpd and may induce oscillation due to interaction with transmission-line stubs.

Is MC10H210MG pin-compatible with MC10H210P or MC10H210L?

No. Although functionally identical, MC10H210MG (SOEIAJ-16), MC10H210P (PDIP-16), and MC10H210L (CDIP-16) have different physical footprints, lead pitches, and thermal characteristics. Their pinouts match electrically (same signal assignments), but mechanical incompatibility prevents direct PCB replacement. Layout redesign is required when switching packages.
