Logic is a fundamental building block of computing. It provides the ability to represent and manipulate data and is essential for efficient programming. Buffers, drivers, receivers, and transceivers are components designed to transmit digital signals in a logic circuit. Each serves a different function and plays an important part in a digital circuit. One type of device is the N74F245DB,118. This article will cover its application fields and working principles.
Application Fields
The N74F245DB,118 is an Octal Transceiver with Bus-Hold, designed for High-Speed data transmission and bidirectional data communication. It is used in logic level-shifting, clock synchronization, and sharing or exchanging data between integrated circuits. It is also used in applications such as Automotive, test equipment, ATM machines, smart cards, and video systems.
Working Principle
The N74F245DB,118 is an octal transceiver with Bus-Hold. It consists of eight back-to-back inverter stages connected in pairs to eight signal lines. The signal is routed from each of its eight differential pairs to an internal latch. Its working principle is based on open-collector technology. When the enable (EN) signal is low, the eight input signal lines are pulled low by the internal logic of the device. When the EN signal is high, the device will transmit data from the latch to its eight output signal lines. It also incorporates Bus-Hold circuitry which maintains its output signal levels when its input is placed in a high impedance state. The Bus-Hold circuit includes a pair of pull-up resistors to ensure a valid logic output level when the input goes high impedance.
Conclusion
The N74F245DB,118 is an Octal Transceiver with Bus-Hold. It is used to level shift and share data between Integrated Circuits. It has many applications in Automotive, testing equipment, ATM machines, smart cards, and video systems. Its working principle is based on open-collector technology with the enable signal controlling the data flow. Its Bus-Hold circuitry ensures the output signal levels are maintained when the signal is in a high impedance state. This is an essential component in many digital circuits forms an important part of Logic.
