onsemi MC10H103PG

Overview

MC10H103PG from ON Semiconductor is a quad 2-input OR gate in MECL 10H logic family, delivering OR/NOR dual outputs per gate with 1.0 ns typical propagation delay, −5.2 V VEE supply operation, and 25 mW/gate power dissipation. It serves as a high-speed combinational logic element in ECL-based timing-critical systems such as telecom line cards and test equipment.

For engineers reviewing the MC10H103PG datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, package-specific terminal mapping, real-world use scenarios, and validated alternative parts for ECL-compatible logic replacement.

Technical Context

The MC10H103PG implements four independent 2-input OR gates using MECL 10H differential emitter-coupled transistor topology, with voltage-compensated biasing to maintain stable switching thresholds across temperature. Each gate features complementary OR and NOR outputs driven by matched emitter-follower pairs.

It operates with VEE = −5.2 V ±5% and VCC1/VCC2 referenced to ground, requiring 50 Ω termination to −2.0 V for specified AC performance. The device meets full MECL 10K pinout and functional compatibility while achieving 100% faster propagation delay without increased supply current.

Key Specifications

Pinout & Package

MC10H103PG is supplied in a Pb-free plastic dual-in-line package (PDIP-16), case 648, with 0.300-inch body width and 0.100-inch lead pitch. Pin 1 is VCC1, Pin 16 is VCC2, and Pin 8 is VEE - all power pins are distributed to minimize ground bounce in high-speed switching.

FAQ

What is the maximum operating temperature for MC10H103PG?

The MC10H103PG is rated for operation from 0°C to +75°C ambient temperature. This specification is guaranteed per Table 1 in the official datasheet, and thermal derating is not required within this range when mounted on a standard PCB with transverse airflow ≥500 lfpm. The MC10H103PG must not be operated outside this envelope without validation.

Does MC10H103PG require external termination resistors?

Yes, the MC10H103PG requires 50 Ω termination to −2.0 V on all outputs to meet its specified AC characteristics, including propagation delay and rise/fall times. This termination is mandatory per Table 3 and Figure 2 of the datasheet; omitting it results in signal integrity degradation and timing violations.

Is MC10H103PG pin-compatible with MC10103?

Yes, MC10H103PG is a functional and pinout duplication of the MECL 10K family part MC10103, as explicitly stated in the datasheet's Description section. Both share identical pin assignments, logic function, and DC/AC specifications - enabling direct substitution without layout changes.

What is the supply current consumption of MC10H103PG?

The MC10H103PG draws 26–29 mA total supply current (IE) across its operating temperature range, measured at VEE = −5.2 V ±5%. This value represents quiescent current for all four gates under static conditions and is confirmed in Table 2 of the datasheet.

Can MC10H103PG be used with +3.3 V or +5 V logic families?

No, MC10H103PG is strictly an MECL device requiring VEE = −5.2 V and VCC = 0 V references. It is incompatible with TTL, CMOS, or LVDS logic families without level-shifting circuitry. Interfacing directly to +3.3 V or +5 V systems will damage the MC10H103PG or cause undefined operation.
