Overview

MC10H106FNG from ON Semiconductor is a triple 4−3−3-input ECL NOR gate in a 20-lead PLLC package, operating at −5.2 V VEE with 1.0 ns typical propagation delay, −1.95 V to −0.735 V output voltage swing, and MECL 10K pinout compatibility. It serves as high-speed logic combiner in telecom line interface timing paths.

For engineers reviewing the MC10H106FNG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, thermal-rated AC performance, Pb-free PLLC package details, and functionally matched alternatives for legacy MECL system upgrades.

Technical Context

The MC10H106FNG implements three independent NOR gates with asymmetric input counts (4, 3, and 3 per gate), each internally terminated for 50 Ω transmission lines to −2.0 V. Its voltage-compensated design maintains stable VIH/VIL thresholds across 0°C to +75°C.

All outputs drive into 50 Ω loads referenced to −2.0 V, enabling direct interfacing with ECL transmission lines without external termination. Propagation delay remains ≤1.55 ns max over full temperature range, with rise/fall times ≤1.9 ns.

FAQ

What is the operating temperature range for MC10H106FNG?

The MC10H106FNG is specified for operation from 0°C to +75°C ambient temperature. This range is validated per Table 2 and Table 3 in the official datasheet, with all electrical and AC parameters guaranteed across this interval. The device must be mounted with transverse airflow >500 lfpm to meet thermal equilibrium requirements. MC10H106FNG does not support industrial or extended temperature grades unless derated per application-specific validation.

Does MC10H106FNG require positive supply voltage (VCC)?

No, MC10H106FNG operates exclusively from a single negative supply (VEE = −5.2 V ±5%). It has no VCC pin and draws current only from VEE. Pins 18, 19, and 20 serve as dedicated VEE returns to minimize ground bounce. This architecture eliminates the need for dual-rail regulation and simplifies power delivery in ECL-based systems using MC10H106FNG.

Is MC10H106FNG pin-compatible with MC10106?

Yes, MC10H106FNG is a functional and pinout duplication of the MECL 10K-series MC10106. Both share identical pin assignments, input/output configurations, and DC logic thresholds. The MC10H106FNG improves propagation delay by 100% without increasing supply current-making it a direct drop-in upgrade for MC10106 in existing designs using the PLLC package variant.

What termination is required for MC10H106FNG outputs?

MC10H106FNG outputs must be terminated with 50 Ω to −2.0 V, as specified in the datasheet's AC characterization conditions. This termination ensures proper signal integrity, meets rise/fall time specs (≤1.9 ns), and guarantees propagation delay performance. Failure to use −2.0 V-referenced 50 Ω termination will result in degraded timing margins and potential logic errors in systems using MC10H106FNG.

How many independent NOR functions does MC10H106FNG provide?

MC10H106FNG provides three independent NOR gates: one with four inputs (A1–A4), and two with three inputs each (B1–B3 and C1–C3). Each gate drives its own output (Aout, Bout, Cout) with no internal sharing. This configuration allows concurrent logic operations-for example, combining frame sync, alarm, and payload enable signals separately-without cross-talk or timing interaction between MC10H106FNG's functional blocks.
