Product details

Overview

MC10103L from ON Semiconductor is a quad 2-input ECL OR gate with OR/NOR complementary 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 MC10103L datasheet, pinout, applications, or equivalent options, key selection criteria include its ECL-compatible voltage thresholds (VOHA = –1.08 V min, VOLA = –1.655 V max), dual-rail supply operation (VCC1/VCC2 = –2.0 V, VEE = –5.2 V), and CDIP-16 package compatibility with legacy MECL 10K systems.

Technical Context

The MC10103L implements true ECL (Emitter-Coupled Logic) topology with differential input pairs and current-switching output stages, enabling rail-to-rail swing between –0.89 V (logic 1) and –1.85 V (logic 0) under +25°C conditions. Its internal architecture supports simultaneous OR and NOR outputs without external inversion.

It operates across –30°C to +85°C with fixed negative supply rails: VEE = –5.2 V, and VCC1/VCC2 = –2.0 V. All four gates share common power and ground terminals, and switching performance is specified with 50 Ω loads terminated to –2.0 V - matching standard ECL transmission line practice.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	ECL 10K series - compatible with industry-standard MECL timing and termination schemes
Propagation Delay	2.0 ns typ - enables ≤500 MHz toggle rates in cascaded logic paths
Rise/Fall Time	2.0 ns typ (20%–80%) - ensures clean signal edges into 50 Ω transmission lines
Power Dissipation	25 mW typ/gate (no load) - requires thermal management in dense layouts
Supply Voltages	VCC1/VCC2 = –2.0 V, VEE = –5.2 V - mandates dual negative supplies; not TTL/CMOS compatible
Output Voltage Swing	VOH = –0.89 V, VOL = –1.85 V @ +25°C - defines valid logic 1/0 windows for receiver threshold alignment
Input Thresholds	VOHA = –1.08 V min, VOLA = –1.655 V max - sets noise margin boundaries for reliable switching

Pinout & Package

Ceramic Dual-In-Line Package (CDIP-16), Case 620, 0.300-inch wide body with hermetic seal - suitable for high-reliability military, aerospace, and test equipment applications where moisture resistance and thermal stability are critical.

Pin/Terminal	Circuit Role	Design Meaning
1, 16	VCC1 / VCC2	Positive supply rails for output stages; both must be connected to –2.0 V
8	VEE	Negative supply rail; connected to –5.2 V reference for all internal current sources
2, 9	AOUT / BOUT	Complementary OR/NOR outputs of Gate A; driven differentially for noise immunity
4, 5	AIN	Differential inputs for Gate A; require matched trace lengths and termination
12, 13	BIN	Differential inputs for Gate B; identical electrical characteristics to AIN pins
3, 7, 6, 10, 11, 14, 15	CIN / DIN / COUT / DOUT	Inputs and outputs for Gates C and D - fully identical to Gates A/B in function and pin mapping

Key Features

Feature	Design Value
Quad independent OR gates	Four fully isolated ECL gates on one die - reduces board space vs discrete solutions
Complementary OR/NOR outputs	Each gate provides both true and inverted logic outputs - eliminates need for external inverters
High-speed switching	2.0 ns propagation delay enables use in >400 Mbps serial data path conditioning
Temperature-stable thresholds	VOHA and VOLA vary <±50 mV over –30°C to +85°C - maintains timing margins across environments
Standard MECL 10K compatibility	Pinout and DC specs match MC10100-series family - allows drop-in replacement in existing designs

Equivalent & Alternatives

The following parts are listed as comparable options for similar ECL OR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC10103P	Same logic function and electrical specs; uses plastic DIP-16 (Case 648) instead of ceramic CDIP-16	Limited to commercial temperature range (0°C to +70°C); lower moisture resistance and thermal conductivity	Select MC10103P only for cost-sensitive, non-military applications with controlled ambient conditions.
MC10103FN	Same logic function and electrical specs; uses PLCC-20 (Case 775) with surface-mount footprint	Requires PCB re-layout; different pinout (see ON Semi DL122/D Pin Conversion Tables); higher I/O density	Choose MC10103FN when upgrading to SMT assembly or increasing gate density per unit area.

Compared with MC10103P and MC10103FN, the MC10103L offers superior thermal stability and hermetic reliability in extended temperature and high-humidity environments - making it the sole choice for deployed avionics, downhole tools, and space-qualified subsystems.

FAQ

What is the operating temperature range for the MC10103L?

The MC10103L is rated for operation from –30°C to +85°C. This extended industrial temperature range is enabled by its ceramic DIP package and ECL process design, making the MC10103L suitable for deployment in base station radios, downhole drilling sensors, and airborne computing modules where ambient conditions exceed commercial-grade limits.

Does the MC10103L require external termination resistors?

Yes - the MC10103L outputs must be terminated with 50 Ω to –2.0 V to meet specified switching times and signal integrity. The datasheet defines all timing parameters (tpd, tr, tf) under this 50 Ω load condition. Without proper termination, the MC10103L exhibits degraded edge rates and potential oscillation due to unterminated transmission lines.

Can the MC10103L interface directly with TTL or CMOS logic?

No - the MC10103L operates with negative supply rails (VEE = –5.2 V, VCC = –2.0 V) and produces ECL-level outputs (–0.89 V / –1.85 V). Direct connection to TTL or CMOS inputs will cause incorrect logic interpretation and potential damage. Level translation via dedicated ECL-to-TTL translators (e.g., MC10124) is required when interfacing with positive-supply logic families.

How many independent logic gates does the MC10103L contain?

The MC10103L contains four independent 2-input OR gates, each with complementary OR and NOR outputs. Pins 2/9, 3/7, 6/10, and 11/14 serve as output pairs for Gates A–D respectively, while corresponding differential input pairs occupy pins 4/5, 12/13, and others as defined in the CDIP-16 pinout - all four gates share VCC1, VCC2, and VEE.

Is the MC10103L still in active production?

While ON Semiconductor has discontinued new wafer starts for the MC10103L, Aetrix Electronics maintains verified legacy inventory with full traceability and extended lifecycle support. The MC10103L remains available for repair, sustainment, and obsolescence-mitigated production runs - backed by lot-specific conformance documentation and burn-in test reports.
