onsemi MC10H211P

Overview

MC10H211P from ON Semiconductor is a dual 3-input/3-output MECL 10K-compatible NOR gate array optimized for low-skew clock distribution and wire-OR logic expansion. It delivers 1.0 ns typical propagation delay, −5.2 V VEE operation, and drives up to six transmission lines simultaneously with three parallel outputs per gate. Its voltage-compensated design ensures stable performance across 0°C to +75°C.

For engineers reviewing the MC10H211P datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, PDIP-16 package details, ECL termination guidance, and validated alternatives for high-speed timing and logic fanout applications.

Technical Context

The MC10H211P implements two independent 3-input NOR gates, each with three identical emitter-follower outputs-enabling true wire-OR capability without external components. All outputs are internally matched for skew control, critical in clock tree synthesis.

It operates exclusively with negative supply (VEE = −5.2 V ±5%) and ground-referenced inputs/outputs, requiring 50 Ω termination to −2.0 V. Its MECL 10K compatibility ensures interoperability with legacy Motorola ECL families while maintaining improved noise margin (150 mV) over temperature and voltage.

Key Specifications

Pinout & Package

MC10H211P uses a 16-pin Plastic Dual-In-Line Package (PDIP-16), case 648, with 0.300-inch body width and through-hole mounting. Pin 1 is top-left corner with notch orientation.

FAQ

What is the recommended termination for MC10H211P outputs?

Each MC10H211P output must be terminated to −2.0 V via a 50 Ω resistor to maintain signal integrity and meet specified rise/fall times. This termination matches standard 50 Ω transmission lines and prevents reflections. The MC10H211P datasheet explicitly states this configuration in Table 2 notes and AN8020/D. Failure to use −2.0 V termination degrades VOH/VOL margins and increases propagation delay variation.

Does MC10H211P support mixed-voltage interfacing, such as with PECL or LVDS?

No, MC10H211P is strictly a negative-supply ECL device operating at VEE = −5.2 V and referenced to ground (VCC1/VCC2 = 0 V). It lacks level-shifting circuitry and is not compatible with PECL (+5 V supply) or LVDS (3.3 V differential) without external translators like the MC100EL16 or SN65LVDS31. Direct connection risks damage or undefined logic states due to voltage domain mismatch.

Can MC10H211P be used in place of MC10H101 in an existing design?

MC10H211P can replace MC10H101 only if the design leverages its dual-gate and triple-output architecture-otherwise, unused outputs must be properly terminated to avoid floating nodes. While both share MECL 10K compatibility and similar DC specs, MC10H211P's pinout differs significantly (e.g., dedicated VCC1/VCC2 and VEE pins), requiring PCB layout changes. It is not a drop-in substitute.

What is the maximum output current rating for MC10H211P?

The MC10H211P supports −50 mA continuous output current per pin and −100 mA surge current, as specified in Table 1. This rating assumes proper −2.0 V termination and adequate heat sinking. Exceeding −50 mA continuously risks exceeding the 160 mW typical power dissipation limit and may cause thermal runaway or parametric shift in VOH/VOL.

Is MC10H211P RoHS compliant?

Yes, the MC10H211P is available in both standard (P suffix) and Pb-free (PG suffix) versions, as confirmed in the Ordering Information table on page 3 of the datasheet. The PG variant meets RoHS Directive 2011/65/EU requirements and uses matte tin lead finish. Both variants share identical electrical and thermal specifications.
