Overview

MC10104P from ON Semiconductor is a quad 2-input ECL AND gate IC with one gate providing both AND and NAND outputs, 2.7 ns typical propagation delay, 2.0 ns typical rise/fall time (20%–80%), and 35 mW typical power dissipation per gate-designed for high-speed logic interfacing in telecom line cards and digital test equipment.

For engineers reviewing the MC10104P datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, PDIP-16 package details, MECL 10K-series timing behavior, and direct alternative options for legacy ECL system upgrades and signal routing designs.

Technical Context

The MC10104P implements four independent 2-input AND gates using MECL 10,000-series bipolar technology, operating with V_CC1 = +5.2 V, V_CC2 = +5.2 V, and V_EE = –5.2 V. Each gate drives into 50 Ω loads terminated to –2.0 V, supporting differential signaling and noise-immune operation.

One gate (pins 12–13 input, pins 15/9 output) provides complementary AND/NAND outputs simultaneously. Input thresholds are defined at VOHA = –0.91 V (logic 1) and VOLA = –1.595 V (logic 0) at +85°C, ensuring stable switching across industrial temperature range.

FAQ

What logic family does the MC10104P belong to, and what supply voltages does it require?

The MC10104P belongs to the MECL 10K (Motorola Emitter-Coupled Logic) family. It requires three supply rails: V_CC1 = +5.2 V (pin 1), V_CC2 = +5.2 V (pin 16), and V_EE = –5.2 V (pin 8). These voltages are strictly defined in the datasheet for proper threshold and output voltage operation; deviation beyond ±5% risks invalid logic states or increased jitter in the MC10104P.

Does the MC10104P support true differential inputs, and how are its inputs biased?

The MC10104P does not include internal biasing resistors and relies on external termination to –2.0 V via 50 Ω for proper differential operation. Inputs are referenced to V_EE, with logic thresholds defined at VOHA = –0.91 V (logic 1) and VOLA = –1.595 V (logic 0) at +85°C. Proper biasing requires matching source impedance and controlled trace lengths-critical for maintaining signal integrity in the MC10104P's high-speed operation.

Which pin provides both AND and NAND outputs on the MC10104P, and how is it configured?

Gate A (inputs on pins 12 and 13) provides both AND and NAND outputs on the MC10104P: pin 15 is the AND output and pin 9 is the NAND output. This dual-output capability is intrinsic to that specific gate and requires no external components-enabling efficient logic inversion or wired-OR functions directly within the MC10104P without adding discrete inverters.

What is the maximum operating temperature for the MC10104P, and how does performance change across temperature?

The MC10104P is specified for operation from –30°C to +85°C. At +85°C, propagation delay increases to 4.2 ns max (vs. 2.7 ns typ at +25°C), and output voltage swing compresses slightly (V_OH = –0.70 V min, V_OL = –1.825 V max). Power dissipation remains stable at 35 mW/gate typ, making thermal derating unnecessary for most MC10104P implementations in ventilated telecom chassis.

Can the MC10104P be used as a direct replacement for the MC10104L in existing designs?

Yes-the MC10104P shares identical pinout, logic function, timing specs, and DC parameters with the MC10104L, differing only in package material (plastic vs. ceramic DIP) and temperature rating. The MC10104P operates from –30°C to +85°C (vs. –55°C to +125°C for MC10104L), so it is a drop-in replacement in all commercial and industrial applications where extended cold operation is not required. Board layout and firmware for the MC10104P remain unchanged.
