onsemi MC10H103MG

Overview

MC10H103MG from ON Semiconductor is a quad 2-input OR gate in MECL 10H logic family, delivering OR/NOR complementary outputs per gate, 1.0 ns typical propagation delay, −5.2 V VEE supply operation, and 25 mW/gate power dissipation. It serves high-speed digital timing and signal routing in telecom line cards and test equipment.

For engineers reviewing the MC10H103MG datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOEIAJ-16), confirmed AC/DC electrical specs across 0–75°C, functional identity as a quad OR gate with dual outputs, and validated alternatives for MECL 10K-compatible designs.

Technical Context

The MC10H103MG implements four independent ECL OR gates, each with true and complement outputs (e.g., Aout/Bout for inputs Ain/Bin). Its voltage-compensated design maintains stable VIH/VIL thresholds across temperature and supply variation.

All gates operate from a single negative supply (VEE = −5.2 V ±5%) referenced to ground, with VCC1 and VCC2 pins internally tied to 0 V. Outputs are terminated to −2.0 V via 50 Ω, meeting standard ECL interface requirements for impedance-matched transmission lines.

Key Specifications

FAQ

What logic family does the MC10H103MG belong to, and is it compatible with older MECL devices?

The MC10H103MG is a MECL 10H logic device and is functionally and pinout-compatible with the MECL 10K family, including the MC10K103. It delivers identical logic behavior and footprint but achieves 100% faster propagation delay without increasing supply current. The MC10H103MG maintains full interoperability with existing 10K-based systems when operated at −5.2 V VEE.

What are the supply voltage requirements for the MC10H103MG?

The MC10H103MG requires a single negative supply: VEE = −5.2 V ±5%. Pins VCC1 (1) and VCC2 (16) are ground-reference terminals and must be connected to the system ground plane. No positive supply is used. Decoupling capacitors (e.g., 0.1 µF ceramic + 10 µF tantalum) are mandatory at the VEE pin to suppress high-frequency noise.

Does the MC10H103MG provide both OR and NOR outputs per gate?

Yes, the MC10H103MG provides true (OR) and complement (NOR) outputs for each of its four gates. For example, inputs Ain/Bin drive outputs Aout (OR) and Bout (NOR); similarly, Cin/Din drive Cout (OR) and Dout (NOR). This dual-output architecture eliminates the need for external inverters in differential signaling or redundant logic paths.

What is the operating temperature range specified for the MC10H103MG?

The MC10H103MG is specified for operation from 0°C to +75°C ambient temperature. This commercial-grade range aligns with typical requirements for central office telecom equipment and benchtop test instruments. Electrical parameters-including propagation delay, noise margin, and output voltage levels-are guaranteed across this full range per the official ON Semiconductor datasheet.

Is the MC10H103MG RoHS-compliant, and what package type does it use?

Yes, the MC10H103MG is Pb-free and RoHS-compliant, using the SOEIAJ-16 surface-mount package (Case 966). It features gull-wing leads, 1.27 mm pitch, and a 10.5 mm × 7.5 mm body. The "G" suffix explicitly denotes the lead-free finish, and the device meets J-STD-020C reflow profile requirements for MSL Level 3 handling.
