Product details

Overview

MC10H103P from ON Semiconductor is a quad 2-input OR gate in MECL 10H logic family, operating with VEE = −5.2 V, delivering 1.0 ns typical propagation delay, −1.95 V to −0.735 V output voltage swing, and 25 mW per gate power dissipation. It serves as high-speed combinational logic in ECL-based timing and control circuits for telecom line cards and test equipment.

For engineers reviewing the MC10H103P datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, package mapping to PDIP-16, thermal-rated AC/DC performance across 0°C to +75°C, and functional alternatives for legacy MECL system upgrades.

Technical Context

The MC10H103P implements four independent OR gates with complementary NOR outputs per gate, using voltage-compensated emitter-coupled logic to maintain stable switching thresholds across temperature. Its design targets direct replacement of MECL 10K parts while improving propagation delay by 100% without increasing supply current.

All outputs are terminated into 50 Ω to −2.0 V per AC test conditions, supporting >500 lfpm airflow for thermal equilibrium. Input voltage range spans −1.95 V to −0.84 V (VIL to VIH), with guaranteed noise margin of 150 mV over full operating temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
Propagation Delay	0.4–1.45 ns (guaranteed across 0°C to +75°C; enables sub-1 GHz clock domain logic)
Output Voltage Swing	−1.95 V to −0.735 V (supports standard ECL-terminated 50 Ω transmission lines)
Power Dissipation	25 mW per gate (identical to MECL 10K, simplifying thermal redesign during upgrade)
Input Voltage Range	VIL = −1.95 V, VIH = −0.84 V min (defines valid logic thresholds under worst-case temp/voltage)
Supply Voltage	VEE = −5.2 V ±5% (requires negative rail; VCC1/VCC2 = 0 V reference)
Operating Temperature	0°C to +75°C (industrial-grade rating; not extended or military)

Pinout & Package

MC10H103P is housed in a 16-pin plastic dual-in-line package (PDIP-16), case 648, with 0.300-inch body width and 0.100-inch lead pitch. Pin 1 = VCC1, Pin 16 = VCC2, Pin 8 = VEE (common emitter return).

Pin/Terminal	Circuit Role	Design Meaning
1, 16	VCC1 / VCC2	Ground-referenced collector supply pins (0 V); both required for proper biasing
8	VEE	Negative supply rail (−5.2 V); common emitter return for all four gates
2, 3, 5, 6, 9, 10, 12, 13	Ain/Bin/Cin/Din (inputs)	Differential input pairs per gate; each accepts ECL-level signals referenced to VEE
4, 7, 11, 14, 15	Aout/Bout/Cout/Dout (OR/NOR)	Complementary outputs per gate; OR active-high (less negative), NOR active-low (more negative)

Key Features

Feature	Design Value
MECL 10K pinout compatibility	Direct drop-in replacement for MC10103/MC10104 without PCB change
Voltage-compensated inputs	Maintains consistent VIH/VIL across −55°C to +125°C storage and 0°C to +75°C operation
150 mV noise margin	Guaranteed immunity to crosstalk and ground bounce in dense backplane layouts
1.0 ns typical tpd	Enables <1 Gbps data path synchronization in bit-error-test and pattern generator systems
Pb-free option available	MC10H103PG meets RoHS Directive 2011/65/EU without derating or performance loss

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MC100H103FN	PLLC-20 package (20-pin), VEE = −4.5 V to −5.5 V, 0.8 ns typical tpd, higher drive strength (±100 mA)	Used in surface-mount high-density designs requiring tighter layout control and lower inductance interconnects	Select when upgrading from through-hole to SMT or when driving longer 50 Ω traces (>6 inches)

FAQ

What is the recommended termination for MC10H103P outputs?

MC10H103P outputs must be terminated with a 50 Ω resistor to −2.0 V, as specified in the AC characteristics table. This termination ensures correct logic levels, minimizes reflections on PCB traces, and guarantees the 0.4–1.45 ns propagation delay across temperature. Failure to use this exact termination invalidates the published timing specs for MC10H103P.

Does MC10H103P require both VCC1 and VCC2 pins to be connected?

Yes, MC10H103P requires both Pin 1 (VCC1) and Pin 16 (VCC2) to be connected to 0 V (ground). These are not redundant; they supply separate internal collector networks. Leaving either unconnected causes undefined output states and violates the Absolute Maximum Ratings, risking latch-up or premature failure of MC10H103P.

Is MC10H103P compatible with MECL 10K logic families?

Yes, MC10H103P is explicitly designed as a functional and pinout duplication of MECL 10K OR gates (e.g., MC10103), with identical pin assignments and DC interface levels. It delivers 100% faster propagation delay while maintaining the same 25 mW/gate power dissipation - making MC10H103P a validated upgrade path without layout changes.

What is the maximum allowable VEE voltage range for MC10H103P?

The absolute maximum VEE rating for MC10H103P is −8.0 V to 0 V, but the device is characterized and guaranteed only at −5.2 V ±5% (i.e., −4.94 V to −5.46 V). Operation outside this range may cause parametric shift or reliability degradation; all published specs - including VOH, VOL, and tpd - apply strictly within the −5.2 V ±5% window for MC10H103P.

Can MC10H103P operate at temperatures beyond +75°C?

No, MC10H103P is rated for 0°C to +75°C only. The datasheet specifies no characterization above +75°C, and maximum ratings for storage (−55°C to +150°C) do not imply operational capability. Attempting to operate MC10H103P above +75°C voids all AC/DC parameter guarantees and risks timing violation or thermal runaway due to uncharacterized leakage currents.
