Logic - Buffers, Drivers, Receivers, Transceivers: 74FCT3245APGG Application Field and Working Principle

The 74FCT3245APGG is a 36-bit bus transceiver with three-state outputs and is designed to be used as a high-speed buffer or bus driver. It is industry-standard logic and one of the most popular logic devices available. This bus transceiver is part of the FCT series, meaning "Fast CMOS Technology," and is now being increasingly used in new products.

The 74FCT3245APGG is used in applications that require high-speed communication between two or more buses of logic. It is also ideal for converting electrical signals from one type of logic to another, as well as for transferring data between buses and devices. This transceiver is also commonly used in memory-mapped systems, and is designed to support applications such as microprocessors, memory controllers, and telecommunications.

The 74FCT3245APGG consists of a receiver and a driver, each with its own 36-bit I/O bus. This means that it can receive data from one bus and quickly transfer it to another. It can also be used to drive up to 36 different I/O loads. This device includes two separateActive High Enable inputs and two Active Low Enable inputs that allow the device to be configured in various functions, such as master-slave, half-duplex, and full-duplex modes.

The 74FCT3245APGG has a high-speed CMOS design with a propagation delay of just 4.5ns (typical). This makes the device suitable for high-speed applications such as memory controllers and high-speed logic systems. The device also has an 8mA static bus drive strength, meaning it can drive up to 18mA into each of the 36 possible loads. It can also handle capacitive loads of up to 400pF.

The 74FCT3245APGG contains five different input and output states. These are High, Low, Tri-State (disabled), High Impedance (disabled) and High Impedance with Pull-Down (enabled). This allows the device to be used in different configurations, such as multi-drop and point-to-point systems. It also has an internal 100K pull-down resistors allowing the device to be reset to a logical level.

The 74FCT3245APGG has a wide operating voltage range (2.7V to 3.6V) and can be operated at up to 20MHz. It has a wide operating temperature range (from -40°C to 85°C) and is housed in a 20-Pin TSSOP package. This device is also available with an I/O supply voltage of 1.8V.

In conclusion, the 74FCT3245APGG is a high-speed and versatile bus transceiver designed for use in high-speed communication and memory-mapped systems. It is ideal for converting electrical signals and transferring data between various devices and buses. Its features include an 8mA static bus drive strength, 100K pull-down resistors, wide operating voltage range, and a wide operating temperature range. Additionally, it is available with an I/O supply voltage of 1.8V.
