onsemi MC10H102FN

Overview

MC10H102FN from onsemi is a quad 2-input NOR gate in MECL 10H logic family, operating with VEE = −5.2 V, delivering 1.0 ns typical propagation delay, −1.95 V to −0.735 V output voltage swing, and 25 mW per gate power dissipation. It serves as high-speed combinational logic in ECL-based timing, data path, and control circuits for telecom line cards and test equipment.

For engineers reviewing the MC10H102FN datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (PLCC-20), terminal functions, noise margin (150 mV), temperature-rated AC performance (0°C to +75°C), and RoHS-compliant Pb-free sourcing at Aetrix Electronics.

Technical Context

The MC10H102FN implements four independent 2-input NOR gates using emitter-coupled logic with differential pair inputs and complementary OR/NOR outputs. Each gate features voltage-compensated biasing to maintain stable switching thresholds across temperature and supply variation.

It is fully compatible with MECL 10K pinouts and logic levels while achieving 100% faster propagation delay without increased supply current. Outputs are designed for 50 Ω termination to −2.0 V, supporting high-fidelity signal integrity in backplane and clock distribution systems.

FAQ

What is the supply configuration required for MC10H102FN?

The MC10H102FN operates exclusively from a single negative supply: VEE = −5.2 V ±5%. It has no VCC connection. All inputs and outputs are referenced to this rail, and outputs must be terminated to −2.0 V via 50 Ω resistors. Proper decoupling (e.g., 0.1 µF ceramic + 10 µF tantalum) near pin 17 (VEE) is mandatory for stable high-speed operation of the MC10H102FN.

Is MC10H102FN pin-compatible with MECL 10K NOR gates?

Yes - the MC10H102FN is a functional and pinout duplication of the MECL 10K-series quad NOR gate. Its PLCC-20 pin assignment mirrors the 10K part's signal mapping, including identical input/output pairing and VEE location. This allows direct substitution in existing 10K designs, provided the PCB land pattern supports PLCC-20 and thermal management accounts for identical 25 mW/gate dissipation in the MC10H102FN.

What is the maximum operating temperature for MC10H102FN?

The MC10H102FN is specified for operation from 0°C to +75°C ambient temperature. Electrical parameters - including propagation delay (0.4–1.4 ns), output voltage swing, and noise margin - are guaranteed across this range. Operation outside this interval is not characterized; for extended temperature use, consider MC100H102FN (−40°C to +85°C), which shares identical functionality and pinout with the MC10H102FN.

Does MC10H102FN support wired-OR bus configurations?

Yes - each of the four gates in the MC10H102FN provides both NOR and OR outputs (pins 9–16). This dual-output architecture enables direct wired-OR connections without external inverters, reducing component count and propagation delay in bus arbitration, interrupt combining, or status aggregation circuits using the MC10H102FN.

How is noise immunity achieved in MC10H102FN?

The MC10H102FN achieves 150 mV guaranteed noise margin across its full operating temperature and voltage range via voltage-compensated internal biasing and tightly controlled differential input thresholds. This design ensures reliable logic decision boundaries even under simultaneous supply ripple and crosstalk - a critical requirement in dense, mixed-signal boards where the MC10H102FN is commonly deployed.
