Logic - Buffers, Drivers, Receivers, Transceivers

SN74ABTH32245PZ is a high-speed, low-power bus transceiver designed with the tri-state ports to provide data transmission between the system and its peripherals by controlling the respective devices. It provides the same performance as conventional transceivers but with lower power consumption.

Application Field

SN74ABTH32245PZ is typically used for point-to-point connections between two systems or devices, such as between a computer system and peripheral devices, remote control systems, and other control logics. In addition, it can be used as a bridge to bridge incompatible buses/interfaces or on a bus where the data rate needs to be increased or decreased. The device can also be used to interface with other components from different families, such as asynchronous and synchronous components.

Working Principle

The SN74ABTH32245PZ follows the two-wire bidirectional data transfer protocol. It comes with the two power pins (Vcc1 and Vcc2), two ground pins (GND1 and GND2), two data lines (SDA and SDB) and two transceiver control lines (OSE and OSEX). The OSE and OSEX lines send control signals to the SN74ABTH32245PZ to make the data transmission process easier and faster.

The SN74ABTH32245PZ is designed to transfer data in both directions at the same speed, ensuring that both sides have the same information. When the device is in the inactive state, both the SDA and SDB lines are in the output low state, and the direction of the data transmission can be changed via the OSE and OSEX signals.

The SDA and SDB lines will go to the input mode with the OSE and OSEX lines being set to ‘1’ (high). This makes the SN74ABTH32245PZ ready for data reception. When this is the case, the SDA and SDB lines will be in an output high state and any data transmission is made possible. The OSE and OSEX lines are then set back to ‘0’ (low) to enable the SN74ABTH32245PZ to return to the inactive state.

The SN74ABTH32245PZ is suitable for data rates up to 50Mbps per channel, with a total data rate up to 200Mbps. It meets the demand of high-speed data transmission applications, making it an ideal choice for use in applications such as high-speed memory and processor buses, audio, video and digital telecommunication equipment, and multiplexing systems.

The SN74ABTH32245PZ is available in various standard formats and packages, such as SOIC-8 and TSSOP-8 packages. It supports both 5V and 3.3V power inputs and offers high ESD protection.

In summary, the SN74ABTH32245PZ is an ideal logic component for high speed data transmission between two systems or devices, featuring low power consumption and high ESD protection. It offers good performance with different power input options, making it suitable for many applications.
