FCT162952ATPACTE4 Datasheet/PDFFCT162952ATPACTE4 Application field and Working Principle
Introduction
FCT162952ATPACTE4 is a family of full CMOS-compatible logic ICs, consisting of logic buffers, drivers, receivers, and transceivers. These devices are used for converting logic levels between different logic families, for driving large capacitive or resistive loads, for extending the length of transmission lines, or for implementing various combined functions. These ICs are available as 8-pin DIPs, 16-pin SOICs and 14-pin SOICs.
Application field
FCT162952ATPACTE4 devices are suitable for applications in the automotive,telecom, datacom and consumer electronics markets. With their low power consumption and single powered voltage, they are ideal for mobile-phone and portable hand-held applications. The devices use CMOS-compatible aluminum-electrolytic capacitors that ensure low noise levels, and they also provide fast switching speeds and excellent process-corner performance.
FCT162952ATPACTE4 devices are used in applications such as data-bus and signal-bus interfaces, network interface cards, smartphones and tablet PCs, embedded systems, consumer electronics, and security systems.
Working principle
The FCT162952ATPACTE4 devices feature full CMOS compatibility, which enables them to operate with signals from other CMOS logic families. Each device contains a collection of logic gates or transceivers packed in an 8-pin DIP or 16-pin SOIC package. The devices are available in 3-state and 4-state versions, with the 4-state version providing additional control over the output signal.
The logic devices feature low threshold voltages and controlled amplitude levels that ensure low EMI emissions and provide compatibility with other logic families. The logic inputs can be connected to an external supply voltage, allowing the devices to function as level shifters or level converters.
The input and output nodes are isolated from one another by an internal junction field-effect transistor (JFET), which provides a high input and output impedance. This ensures that the logic signals remain undistorted and that the device does not consume any power.
The logic devices also feature low propagation delays, which make them suitable for use in high-speed applications. The devices are protected from static discharge and over-voltages, and have been tested to ensure reliable operation in automotive, telecom, and consumer electronics markets.
