Overview

MC10102P from ON Semiconductor is a quad 2-input ECL NOR gate IC with OR/NOR dual outputs per gate, −5.2 V VEE supply, 2.0 ns typical propagation delay, and 25 mW typical power dissipation per gate - used in high-speed digital logic systems including telecom line interface timing and differential signal routing.

For engineers reviewing the MC10102P datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, PDIP-16 package mapping, gate-level timing behavior, and functionally comparable alternatives for ECL logic design validation and board-level replacement.

Technical Context

The MC10102P implements four independent ECL (Emitter-Coupled Logic) NOR gates in a single PDIP-16 package, each supporting both true (NOR) and complemented (OR) outputs. It operates with a negative VEE = −5.2 V supply and requires termination to −2.0 V via 50 Ω resistors for specified switching performance.

All gates are electrically identical and characterized under thermal equilibrium with transverse airflow >500 fpm. Propagation delays (t_pd) and rise/fall times (t_r, t_f) are measured at 20–80% transitions into 50 Ω loads, with VOH = −0.890 V (min), VOL = −1.890 V (max) at +25°C.

Key Specifications

Pinout & Package

MC10102P is supplied in a 16-pin plastic dual-in-line package (PDIP-16), Case 648–08, with 0.300-inch width and standard through-hole mounting footprint.

Equivalent & Alternatives

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

Compared with MC10102L and MC10102FN, the MC10102P offers cost-effective through-hole assembly with identical logic functionality and timing, but lacks the thermal robustness of ceramic packaging or the density advantage of PLCC - making it optimal for industrial prototyping and low-volume ECL subsystems.

FAQ

What logic family does the MC10102P belong to, and how does it differ from TTL or CMOS?

The MC10102P belongs to the ECL (Emitter-Coupled Logic) 10,000 series family. Unlike TTL or CMOS, it operates with a negative VEE supply (−5.2 V), delivers differential outputs, and achieves sub-3 ns propagation delays with inherent noise immunity. The MC10102P requires 50 Ω termination to −2.0 V and cannot interface directly with TTL/CMOS logic without level translation.

What are the correct power supply connections for the MC10102P?

The MC10102P requires VCC1 and VCC2 (pins 1 and 16) connected to ground, and VEE (pin 8) connected to −5.2 V. Outputs must be terminated to −2.0 V via 50 Ω resistors to meet specified timing and voltage levels. Failure to apply correct termination results in degraded t_pd, t_r, and t_f performance.

Does the MC10102P support both true and complemented outputs on each gate?

Yes - each of the four gates in the MC10102P provides both NOR (true) and OR (complemented) outputs. For example, Gate A uses pins 2 and 3 as inputs, pin 4 as AOUT (NOR), and pin 7 as BOUT (OR). This dual-output architecture eliminates external inverters in feedback or control loops.

What is the guaranteed operating temperature range for the MC10102P?

The MC10102P is rated for operation from −30°C to +85°C. Electrical characteristics including VOH, VOL, t_pd, and I_E are fully specified across this range, with typical values (e.g., 2.0 ns t_pd) measured at +25°C and validated at extremes per the ON Semiconductor datasheet Rev. 7.

Can the MC10102P be used as a drop-in replacement for the MC10102L or MC10102FN?

No - while functionally identical, the MC10102P (PDIP-16) is not pin-compatible with MC10102L (CDIP-16, different leadform) or MC10102FN (PLCC-20, 20-pin layout). Each variant requires distinct PCB footprints and thermal management approaches; substitution necessitates board redesign.
