onsemi MC10H210M

Overview

MC10H210M from ON Semiconductor is a dual 3-input/3-output MECL 10K-compatible OR gate designed for high-speed clock distribution and wire-OR logic applications. It delivers typical propagation delay of 1.0 ns, power dissipation of 160 mW, and operates across 0°C to +75°C with VEE = −5.2 V ±5%. Its three parallel outputs per section enable simultaneous driving of up to six transmission lines with minimized skew.

For engineers reviewing the MC10H210M datasheet, pinout, applications, or equivalent options, this device is selected for low-skew clock fanout, ECL-level wired-OR bus implementation, and high-speed logic gating where sub-2 ns timing margins are critical.

Technical Context

The MC10H210M implements two independent 3-input OR gates, each with three identical open-emitter outputs-enabling direct wire-OR connection without external diodes. Each output drives a 50 Ω load terminated to −2.0 V, meeting MECL 10K voltage thresholds (VIH = −1.17 V min, VIL = −1.95 V max at 25°C).

Its internal voltage-compensated design maintains stable noise margin (150 mV) across temperature and supply variation. Propagation delay (tpd = 0.5–1.7 ns), rise/fall times (tr/tf = 0.75–2.0 ns), and output voltage swing (VOH = −1.02 V to −0.735 V, VOL = −1.95 V to −1.60 V) are fully characterized over 0°C to +75°C.

FAQ

What is the recommended termination for MC10H210M outputs?

Each MC10H210M output must be terminated with a 50 Ω resistor to −2.0 V. This termination is mandatory to meet specified VOH/VOL levels, ensure signal integrity, and guarantee propagation delay performance. Failure to apply correct termination results in degraded noise margin and increased tpd variation across temperature.

Does MC10H210M support mixed-voltage interfacing with TTL or CMOS logic?

No-MC10H210M is strictly MECL 10K-compatible and operates with negative supply (VEE = −5.2 V). Direct interfacing with TTL or CMOS requires level-shifting circuitry (e.g., MC10H605 translator) due to incompatible voltage domains and current-sinking output architecture.

Is MC10H210M pin-compatible with MC10H210P or MC10H210L?

No-MC10H210M (SOEIAJ-16), MC10H210P (PDIP-16), and MC10H210L (CDIP-16) share identical logic function and electrical specs but differ in pin assignment due to package-specific leadframe layout. The SOEIAJ pinout is unique and not interchangeable without PCB redesign.

What is the maximum output current rating for MC10H210M?

The MC10H210M supports continuous output current of ±50 mA per output terminal, with surge capability up to ±100 mA. Exceeding these limits risks parametric shift or permanent damage, especially under sustained DC loading without proper termination.

How does the voltage compensation feature improve noise immunity in MC10H210M?

The voltage compensation circuitry in MC10H210M dynamically adjusts internal bias points to maintain constant differential input threshold (VIH − VIL) across VEE variation and temperature. This ensures the 150 mV noise margin remains stable from 0°C to +75°C and ±5% VEE tolerance-eliminating need for external trim components.
