Product details

Overview

MC10H102MELG 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, 25 mW per gate power dissipation, and 150 mV improved noise margin across 0°C to +75°C - used in high-speed digital control and timing circuits in telecom line cards and test equipment.

For engineers reviewing the MC10H102MELG datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed sub-1.4 ns max propagation delay at 75°C, MECL 10K pinout compatibility, −1.95 V to −0.735 V output voltage swing, and Pb-free PLCC-20 packaging for surface-mount reliability in dense backplane interfaces.

Technical Context

The MC10H102MELG implements four independent 2-input NOR gates using emitter-coupled logic with differential input structure and complementary OR/NOR outputs per gate. It operates with a single negative supply (VEE = −5.2 V ±5%) referenced to ground, requiring 50 Ω termination to −2.0 V for specified AC performance.

All gates share common VCC1 (Pin 1), VCC2 (Pin 16), and VEE (Pin 8) rails. Input thresholds (VIH/VIL) and output levels (VOH/VOL) are voltage-compensated across temperature, enabling stable operation without external biasing in multi-gate timing chains.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	MECL 10H - ensures interoperability with legacy MECL 10K systems while halving propagation delay
Propagation Delay (tpd)	0.4–1.4 ns - guarantees sub-1.4 ns worst-case gate delay at +75°C for synchronous pipeline stages
Power Dissipation	25 mW/gate - matches MECL 10K consumption despite speed improvement, minimizing thermal load
Noise Margin	150 mV - provides robust immunity to crosstalk and supply ripple in high-density ECL backplanes
Supply Voltage	VEE = −5.2 V ±5% - requires precision negative rail; VCC pins internally tied to ground reference
Operating Temperature	0°C to +75°C - validated for commercial-grade telecom infrastructure and automated test equipment
Input Current (IinL)	0.3–0.5 mA low-level - defines pull-down strength needed for driving adjacent ECL inputs

Pinout & Package

MC10H102MELG is packaged in a 20-lead plastic leaded chip carrier (PLCC), case 775−02, with gull-wing leads and JEDEC-standard footprint. Pin 1 is marked by a notch or dot; package is RoHS-compliant and Pb-free.

Pin/Terminal	Circuit Role	Design Meaning
1, 16	VCC1 / VCC2	Ground-referenced supply pins - internally connected to system GND; required for bias stability
8	VEE	Negative supply rail (−5.2 V) - powers all four NOR gates and sets logic threshold reference
2, 3, 5, 6, 10, 11, 13, 14	Ain/Bin/Cin/Din & Aout/Bout/Cout/Dout	Differential input/output pairs per gate - each gate has dedicated input and complementary OR/NOR outputs
4, 7, 9, 12, 15	Unused / NC	No-connect terminals - left unconnected per datasheet; no internal connection or function

Key Features

Feature	Design Value
Propagation delay reduction	100% faster than MECL 10K - enables higher clock rates in existing pin-compatible layouts
Voltage compensation	Maintains VIH/VIL and VOH/VOL stability over full temperature range - eliminates need for external trimming
MECL 10K pinout duplication	Direct drop-in replacement for MC10K102 - preserves PCB layout and interconnect integrity
Noise margin enhancement	150 mV minimum - supports reliable operation in noisy switching environments like power supply monitoring circuits
Pb-free & RoHS compliance	Meets EU Directive 2011/65/EU - qualified for industrial and telecom applications requiring green manufacturing

Equivalent & Alternatives

The following parts are listed as comparable options for similar NOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC10K102FNR2G	MECL 10K family; 2.0 ns typical tpd; same PLCC-20 package; higher power supply current (32 mA vs. 26–29 mA)	Legacy design reuse where speed < 1.5 ns not required; lower noise margin (≈100 mV)	Select when backward compatibility with older 10K designs is mandatory and thermal budget allows higher dissipation

FAQ

What is the supply voltage requirement for MC10H102MELG?

The MC10H102MELG requires a single negative supply of VEE = −5.2 V ±5%, with VCC1 and VCC2 pins connected to ground. This configuration establishes the proper bias for its emitter-coupled logic structure. The MC10H102MELG does not operate from positive supplies; incorrect voltage application will prevent functional operation and may damage the device.

Is MC10H102MELG pin-compatible with MC10K102?

Yes, the MC10H102MELG is a functional and pinout duplication of the MC10K102, supporting direct replacement in existing PLCC-20 layouts. All input, output, and supply pins align identically between the two devices. The MC10H102MELG maintains the same mechanical footprint and solder-reflow profile, enabling drop-in upgrades without PCB modification.

What termination is required for MC10H102MELG outputs to meet AC specifications?

To achieve guaranteed AC performance including 1.4 ns max propagation delay, MC10H102MELG outputs must be terminated with a 50 Ω resistor to −2.0 V. This termination establishes the correct load condition for rise/fall time and delay measurements. Failure to apply this termination results in degraded timing performance and potential signal integrity issues in high-speed interconnects.

Does MC10H102MELG support operation at extended temperature ranges?

No, the MC10H102MELG is characterized and rated for 0°C to +75°C only. Its electrical specifications - including propagation delay, noise margin, and output voltage swing - are guaranteed only within this commercial temperature range. For industrial or automotive applications requiring −40°C to +85°C, alternate solutions such as the MC100EP102 must be evaluated.

How many functional gates does MC10H102MELG contain?

The MC10H102MELG contains four independent 2-input NOR gates, each with complementary OR and NOR outputs. Pins 2–3, 5–6, 10–11, and 13–14 serve as input/output pairs for Gates A–D respectively. Unused pins (4, 7, 9, 12, 15) are no-connect and must remain unconnected in circuit design.
