SSTUG32868ET/S,518

Introduction

SSTUG32868ET/S,518, is a specialty logic device in the specialized logic family. It is a digital integrated circuit manufactured as an emitter-coupled logic (ECL) device. ECL consists of a series of three stable states, known as discrete logic levels. In this device, the logic levels are "high"(which corresponds a voltage level of approximately +3.3V), "low" (which corresponds to a voltage level of approximately -3.3V), and "undefined"(which corresponds to a voltage level of 0V).

Design and Architecture

The SSTUG32868ET/S,518 Specialty Logic device is an emitter-coupled logic (ECL) device. It is a monolithic integrated circuit with a power of 3.3 VDC and a temperature range of -40 to +100 °C. Its architecture consists of three levels: high, low, and undefined. The logic levels are defined by voltage levels. The input voltage level should be between 3.2 and 3.6V for a logic high, between -4.4 and 0V for a logic low, and between -1.7 and 1.7V for an undefined logic level. The transition time between the high and low logic levels is about 15 ns. The power consumption of SSTUG32868ET/S,518 is about 100 mW.

Working Principle

The SSTUG32868ET/S,518 works on ECL logic by using two transistors, connected in parallel, to create an up-down transition when a signal is driven. The transistors are coupled and differential (saddleback) to maintain the transition. A logic low is expected when the output is made to saturate. The current gain of the transistors is increased by increasing the value of the polarizing voltage. The voltage level in the circuit when the logic low is generated is approximately -3.3V, while the voltage level in the circuit when the logic high is generated is approximately +3.3V. When the circuit is in the undefined state, the voltage level present is 0V.

Conclusion

The SSTUG32868ET/S,518 is an ECL device used in various fields such as high speed computing, communication networks, and medical systems. The logic levels of the device are defined by voltage levels, wherein a logic high is represented by a voltage level of +3.3V, logic low is represented by a voltage level of -3.3V, and an undefined state is represented by voltage level of 0V. It requires a transistor pair for proper functionality and the operation of the device is governed by the principles of ECL.
