This document describes the MC1000/1200 series of MECL II logic devices, specifically models MC1001 through MC1003 and MC1201 through MC1203. These devices are designed to provide simultaneous OR/NOR or AND/NAND output functions and feature an internal bias reference to ensure the threshold point remains centered over the temperature range. The datasheet details the electrical characteristics, including power dissipation, input/output voltages, and switching times for various fan-out conditions.
| Logic Family | MECL II |
|---|---|
| Output Functions | Simultaneous OR/NOR or AND/NAND |
| Power Dissipation (MC1001/MC1201) | 115 mW typical |
| Power Dissipation (MC1002/MC1202) | 80 mW typical |
| Power Dissipation (MC1003/MC1203) | 40 mW typical |
| Propagation Delay (Fan-Out = 3) | 40 ns typical |
| Output Impedance (Tied Outputs) | About 2 ohms |
These devices provide simultaneous OR/NOR or AND/NAND output functions.
The internal bias reference insures that the threshold point is always in the center of the transition region over the temperature range.
The typical power dissipation for the MC1001 is 115 mW.
