onsemi MC10H104FNG

Overview

MC10H104FNG from ON Semiconductor is a quad 2-input MECL 10H™ AND gate with one gate providing both AND and NAND outputs, propagation delay of 1.0 ns (typ), power dissipation of 25 mW/gate, and operation over 0°C to +75°C. It serves as a high-speed logic building block in ECL-based timing, data path, and control circuits for telecom line cards and test equipment.

For engineers reviewing the MC10H104FNG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, package dimensions, functional compatibility with MECL 10K, noise margin performance, and real-world substitution guidance for legacy ECL system upgrades.

Technical Context

The MC10H104FNG implements four independent 2-input AND gates using MECL 10H differential emitter-coupled logic, with VEE = −5.2 V ±5% and termination to −2.0 V via 50 Ω. One gate provides complementary AND/NAND outputs, enabling direct implementation of XOR/XNOR functions without external inversion.

It maintains full pinout and functional equivalence with MECL 10K-series counterparts while delivering 100% faster propagation delay (tpd ≤ 1.9 ns max at +75°C) without increased supply current-IE remains ≤ 39 mA across temperature, supporting stable high-frequency operation in synchronous systems.

FAQ

What is the supply voltage configuration required for MC10H104FNG?

The MC10H104FNG operates with a negative supply referenced to ground: VEE = −5.2 V ±5%, while VCC1 and VCC2 are tied to 0 V (ground). This dual-supply ECL configuration mandates proper −2.0 V termination for all outputs via 50 Ω resistors. The MC10H104FNG does not support positive-only or single-supply operation.

Is MC10H104FNG pin-compatible with MC10K104 series devices?

Yes, MC10H104FNG is a functional and pinout duplication of the MECL 10K series quad AND gate. All 20 pins-including VCC1/VCC2, VEE, inputs, and outputs-match MC10K104L/P/FN packages. No PCB layout changes are needed when upgrading from MC10K104 to MC10H104FNG.

Does MC10H104FNG support Pb-free soldering processes?

Yes, MC10H104FNG is manufactured in a Pb-free PLLC−20 package (Case 775) and complies with JEDEC J-STD-020 moisture sensitivity level 3. Reflow profiles must follow ON Semiconductor's Soldering and Mounting Techniques Reference Manual (SOLDERRM/D) for optimal joint reliability.

What is the significance of the dual VCC pins (Pins 1 and 16) on MC10H104FNG?

The dual VCC pins (Pins 1 and 16) on MC10H104FNG provide separate low-inductance return paths for internal gate clusters, reducing supply noise coupling between logic sections. This layout minimizes timing skew and improves noise immunity in high-density ECL designs-critical for maintaining signal integrity in MC10H104FNG-based clock trees.

Can MC10H104FNG be used in place of MC10H104FN without design changes?

Yes, MC10H104FNG and MC10H104FN share identical logic function, pinout, DC/AC specifications, and PLLC−20 packaging-the only difference is the Pb-free plating (G suffix) on MC10H104FNG. All thermal, electrical, and mechanical characteristics remain unchanged, making MC10H104FNG a direct drop-in replacement for MC10H104FN.
