onsemi MC10H102P

Overview

MC10H102P from ON Semiconductor is a quad 2-input NOR gate in MECL 10H™ logic family, operating at −5.2 V VEE with 1.0 ns typical propagation delay, 25 mW/gate power dissipation, and 150 mV improved noise margin. It serves as a high-speed logic building block in ECL-based timing, control, and data path circuits for telecom line cards and test equipment.

For engineers reviewing the MC10H102P datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed sub-1.4 ns propagation delay across 0–75°C, MECL 10K™ pinout compatibility, voltage-compensated output swing, and PDIP-16 packaging for through-hole prototyping and legacy system repair.

Technical Context

The MC10H102P implements four independent 2-input NOR gates using emitter-coupled logic with differential pair inputs and complementary OR/NOR outputs per gate. Its voltage-compensated design maintains stable VOH (−0.84 to −1.02 V) and VOL (−1.60 to −1.95 V) across temperature and supply variation.

All gates share common VCC1 (Pin 1), VCC2 (Pin 16), and VEE (Pin 8) rails. Input current ranges are specified as IinH ≤ −265 µA and IinL ≥ +0.3 µA at 75°C, supporting robust noise immunity in high-speed backplane environments.

FAQ

What is the maximum operating temperature for the MC10H102P?

The MC10H102P is rated for continuous operation from 0°C to +75°C, as confirmed in Table 1 of the official datasheet. This range applies to both commercial telecom and industrial instrumentation use cases. Thermal derating is not required within this envelope, and the device maintains full AC/DC specifications-including 1.4 ns max propagation delay-across the entire span. The MC10H102P does not support extended temperature grades.

Is the MC10H102P pin-compatible with MECL 10K™ devices?

Yes, the MC10H102P is explicitly designed as a functional and pinout duplication of the standard MECL 10K™ quad NOR gate. Its PDIP-16 pin assignment matches legacy 10K™ parts exactly, including VCC1 (Pin 1), VCC2 (Pin 16), and VEE (Pin 8) placement. This allows direct replacement in existing 10K™ designs without PCB modification, as stated in the device description and Figure 2 of the MC10H102P datasheet.

What is the recommended termination for MC10H102P outputs?

MC10H102P outputs must be terminated with a 50 Ω resistor to −2.0 V, as specified in Note 1 of Table 2. This termination ensures proper signal integrity, meets VOH/VOL specifications, and maintains the 1.0 ns typical propagation delay. Failure to apply this exact termination results in undefined timing behavior and violates the test conditions under which all AC parameters-including tpd, tr, and tf-are guaranteed.

Does the MC10H102P require both positive and negative supply rails?

No, the MC10H102P operates solely from a single negative supply rail (VEE = −5.2 V ±5%). Pins 1 (VCC1) and 16 (VCC2) are not positive supply inputs-they serve as bias terminals for internal emitter followers and must be connected to ground or a low-impedance return path, not to a positive voltage. This configuration is fundamental to MECL 10H™ operation and is clearly shown in the logic diagram and pin assignment.

How does the MC10H102P achieve improved noise margin versus MECL 10K™?

The MC10H102P achieves a 150 mV noise margin through voltage compensation circuitry that dynamically stabilizes output voltage levels across temperature and supply variation. This design ensures VOH remains tightly bounded between −1.02 V and −0.84 V, and VOL between −1.95 V and −1.60 V-even at 75°C-thereby widening the valid logic window beyond what standard 10K™ parts guarantee. This specification is measured and verified per Table 2.
