onsemi MC10H100MG

Overview

MC10H100MG from ON Semiconductor is a quad 2-input NOR gate with strobe, implemented in MECL 10H logic family, featuring 1.0 ns typical propagation delay, −5.2 V VEE supply, and SOEIAJ-16 surface-mount package. It integrates a common strobe input shared across all four gates and operates over 0°C to +75°C for high-speed digital control in telecom timing and test equipment.

For engineers reviewing the MC10H100MG datasheet, pinout, applications, or equivalent options, key selection criteria include its MECL 10H compatibility, guaranteed AC performance at 75°C, −1.95 V to −0.735 V output voltage swing, and Pb-free SOIC packaging for lead-free assembly compliance.

Technical Context

The MC10H100MG implements four independent NOR gates, each with two dedicated inputs plus one globally shared strobe input (Pin 9), enabling synchronized enable/disable of all gates. Its differential ECL topology ensures fast switching with matched rise/fall times and voltage-compensated thresholds.

Designed for −5.2 V ±5% VEE supply (VCC1 = Pin 1, VCC2 = Pin 16, VEE = Pin 8), it delivers rail-to-rail logic swing between −1.95 V (VOL) and −0.735 V (VOH) at 75°C, with termination to −2.0 V via 50 Ω resistors per output - a requirement for stable MECL 10H signal integrity.

FAQ

What is the recommended termination for MC10H100MG outputs?

The MC10H100MG requires 50 Ω resistive termination to −2.0 V for each output to meet specified AC performance, including propagation delay and rise/fall time. This termination stabilizes the differential ECL output stage and prevents reflections in high-speed traces. The MC10H100MG datasheet explicitly states this condition applies during all AC characterization - failure to implement it will degrade timing margins and increase jitter. Always verify termination placement near the load, not at the source.

Does MC10H100MG support true 3-input NOR logic per gate?

No - the MC10H100MG implements a 2-input NOR function per gate, augmented by a single strobe input (Pin 9) shared across all four gates. Each gate evaluates two dedicated inputs (e.g., Pins 4 & 6 for Gate A) AND the common strobe. The logic equation is Y = NOT(A + B + STROBE), not a three independent-input NOR. This architecture enables synchronized gating but does not provide fully independent 3-input functionality per gate.

Can MC10H100MG operate with VEE = −4.5 V instead of −5.2 V?

No - the MC10H100MG is characterized and guaranteed only at VEE = −5.2 V ±5% (i.e., −4.94 V to −5.46 V). Operation outside this range violates maximum ratings and invalidates all published DC and AC specifications, including VOH, VOL, propagation delay, and noise margin. The internal voltage compensation circuitry is calibrated for −5.2 V; deviation risks latch-up or parametric failure.

Is MC10H100MG pin-compatible with MC10H100M?

Yes - MC10H100MG and MC10H100M share identical SOEIAJ-16 package dimensions, pin assignment, and electrical specifications; the only difference is the Pb-free finish on MC10H100MG. Both parts use Case 966, 16-pin gull-wing layout with identical thermal and mechanical footprints, enabling direct substitution in reflow assembly without PCB modification.

What is the function of duplicate input pins (e.g., Pins 4 & 5, 6 & 7) on MC10H100MG?

Pins 4 & 5 are internally bonded together as the first independent input pair for Gate A; similarly, Pins 6 & 7 serve Gate B, Pins 12 & 13 serve Gate D, and Pins 14 & 15 serve Gate C. This duplication eases PCB routing by allowing flexible fan-in placement without vias. The MC10H100MG datasheet confirms these pairs are electrically shorted within the die - they do not represent separate logic inputs or differential pairs.
