Product details
Overview
MC10103P from ON Semiconductor is a quad 2-input ECL OR gate with complementary OR/NOR outputs per gate, designed for high-speed logic interfacing in telecom and instrumentation systems. It delivers 2.0 ns typical propagation delay, 2.0 ns typical rise/fall time (20%–80%), and 25 mW typical power dissipation per gate at no load.
For engineers reviewing the MC10103P datasheet, pinout, applications, or equivalent options, key selection criteria include ECL-compatible voltage thresholds (VOH = –0.89 V typ, VOL = –1.675 V typ), dual VCC supply (VCC1/Pin 1, VCC2/Pin 16), and negative rail operation (VEE = –5.2 V at Pin 8).
Technical Context
The MC10103P implements four independent ECL gates in a single PDIP-16 package, each providing true and complemented outputs (e.g., AOUT/BOUT for inputs AIN/AIN). It operates with split supplies: VCC1 and VCC2 referenced to ground, and VEE at –5.2 V, enabling differential signaling and noise-immune logic transitions.
All gates are fully compatible with MECL 10,000 series standards, supporting termination into 50 Ω to –2.0 V. Input thresholds are defined by VIHAmin (–1.105 V) and VILAmax (–1.475 V) at +25°C, ensuring robust noise margins in high-frequency clock distribution and data path gating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 2.0 ns typical - enables ≤500 MHz toggle rate in critical timing paths |
| Rise/Fall Time | 2.0 ns typical (20%–80%) - supports clean edge integrity into 50 Ω loads |
| Supply Voltages | VCC1/VCC2 = GND; VEE = –5.2 V - requires negative rail for proper ECL biasing |
| Output Voltage Logic 1 | VOH = –0.810 V min at +25°C - defines high-state compatibility with downstream MECL receivers |
| Output Voltage Logic 0 | VOL = –1.650 V max at +25°C - ensures ≥0.7 V noise margin under worst-case loading |
| Power Dissipation | 25 mW typical per gate (no load) - dictates thermal layout for multi-gate density on PCB |
Pinout & Package
MC10103P is housed in a 16-pin plastic dual-in-line package (PDIP-16, Case 648), with 0.300-inch body width and standard through-hole mounting. Pin 1 is VCC1, Pin 16 is VCC2, and Pin 8 is VEE (–5.2 V). The package is RoHS-compliant and rated for industrial temperature range (–30°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VCC1 / VCC2 | Positive supply terminals tied to ground - essential for ECL reference point |
| 8 | VEE | Negative supply input at –5.2 V - sets logic swing and bias current |
| 2, 9 | AOUT / BOUT | Complementary OR outputs for Gate 1 - enables wired-OR or differential routing |
| 4, 5 | AIN / AIN | Differential input pair for Gate 1 - accepts true/complement signals for noise rejection |
| 12, 13 | BIN / BIN | Differential input pair for Gate 2 - identical structure to AIN/AIN |
| 10, 11 | COUT / DOUT | OR/NOR outputs for Gates 3 and 4 - supports independent 2-input logic per channel |
| 3, 6, 7, 14, 15 | Unused / NC | No-connect pins - must remain unconnected per datasheet guidance |
Key Features
| Feature | Design Value |
|---|---|
| Quad 2-input OR architecture | Four independent gates in one package - reduces board space vs discrete solutions |
| Complementary OR/NOR outputs | Each gate provides both true and inverted outputs - eliminates need for external inverters |
| MECL 10,000 series compliance | Fully interoperable with industry-standard ECL families - ensures system-level signal integrity |
| 50 Ω load-optimized switching | Specified with 50 Ω termination to –2.0 V - matches coaxial transmission line impedance |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECL OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC100EL01P | Single 2-input OR gate, same PDIP-16 package, identical VEE = –5.2 V and VOH/VOL specs | Provides only one OR gate instead of four - suitable when gate count is not constrained | Select when lower gate density suffices and board area is less critical than part commonality |
| SN65ELT22D | 3.3 V PECL-compatible OR gate; VCC = +3.3 V, VEE = GND; incompatible supply scheme | Requires positive-rail PECL infrastructure - not drop-in replaceable due to opposite polarity supply | Choose only when migrating to modern PECL systems; redesign of power and termination required |
Compared with MC100EL01P and SN65ELT22D, the MC10103P uniquely delivers quad-gate density with legacy MECL 10K compatibility and negative-supply operation - critical for maintaining signal integrity in existing high-speed analog-digital hybrid systems without re-engineering power distribution.

FAQ
What is the correct power supply configuration for MC10103P?
The MC10103P requires three supply connections: VCC1 (Pin 1) and VCC2 (Pin 16) must be connected to ground, while VEE (Pin 8) must be supplied with –5.2 V. This negative-rail configuration establishes the proper bias for ECL logic levels. Applying positive voltage to VCC pins or omitting the VEE rail will prevent correct operation of MC10103P and may cause excessive current draw or latch-up.
Does MC10103P support single-ended input operation?
No, MC10103P does not support reliable single-ended input operation. Its inputs (e.g., AIN/AIN, BIN/BIN) are differential pairs designed for true/complement signal reception. Driving only one side violates the internal current-switch topology and degrades noise immunity, propagation delay matching, and threshold stability. For MC10103P to function correctly, both inputs of each pair must be driven with complementary signals referenced to VEE.
What is the maximum operating frequency supported by MC10103P?
The MC10103P is characterized for operation up to 500 MHz toggle rate, derived from its 2.0 ns typical propagation delay and 2.0 ns typical rise/fall time. However, actual maximum frequency depends on PCB layout, termination quality, and load capacitance. For sustained 500 MHz operation, MC10103P must be used with 50 Ω source and load terminations referenced to –2.0 V, as specified in the official ON Semiconductor datasheet.
Can MC10103P be used with TTL or CMOS logic families?
MC10103P cannot interface directly with TTL or CMOS logic without level translation. Its output voltages (VOH ≈ –0.81 V, VOL ≈ –1.65 V) fall outside TTL/CMOS input thresholds. To integrate MC10103P with TTL or CMOS systems, dedicated ECL-to-TTL translators (e.g., MC10124) or resistor-based bias networks are required. Direct connection risks undefined logic states and potential damage due to reverse-biased input protection diodes in CMOS devices.
Is MC10103P still in active production and supported by onsemi?
MC10103P is a legacy device originally released in 2002 and is now listed as NRND (Not Recommended for New Designs) by onsemi. While not actively promoted, it remains available through authorized distributors and Aetrix Electronics with full traceability. Engineering support, datasheets, and application notes are archived and accessible via onsemi.com, and MC10103P continues to be sourced for legacy system repair and long-lifecycle industrial deployments.
