ON Semiconductor MC74LCX652DTR2

The ON Semiconductor MC74LCX652DTR2 is a high-performance, low-voltage CMOS 8-bit registered transceiver with LVTTL-compatible inputs and outputs. This integrated circuit is designed to be used in applications that require bidirectional communication and data flow between two buses. The MC74LCX652DTR2 is part of ON Semiconductor's LCX range of products, which are known for their low power consumption and high noise immunity, making them suitable for a wide array of digital applications.

The device features two sets of eight-bit bus transceivers with 3-state outputs, allowing for bidirectional communication between two buses. The direction of data flow is determined by the DIR input, while the output enable (OE) input can disable the device's outputs to allow for multiple devices to share a common bus line. This is particularly useful in multiplexed bus applications, where multiple transceivers can exist on the same bus without interference.

Operating from a 2.3V to 3.6V power supply, the MC74LCX652DTR2 is specifically designed for low-voltage operation, which helps to reduce the overall power consumption of the system it is integrated into. This feature, combined with a 5V tolerant I/O, allows for interfacing with mixed-voltage systems, providing designers with greater flexibility in system-level design.

The transceiver's performance is optimized for high-speed signaling over long bus lines in noisy environments. It can support signaling rates up to 240 Mbps, making it an excellent choice for high-speed data transfer applications. The device also includes built-in 26Ω series resistors on the bus lines, which helps to reduce line noise and minimize reflections, thus enhancing signal integrity.

Available in a TSSOP-24 package, the MC74LCX652DTR2 is also designed with a small footprint, saving valuable board space in compact electronic systems. Its robust design ensures it can operate over the industrial temperature range of -40°C to +85°C, making it suitable for industrial applications where extreme temperatures can be encountered.

In summary, the MC74LCX652DTR2 from ON Semiconductor is a versatile, low-voltage 8-bit registered transceiver that offers high-speed operation, low power consumption, and reliable performance, making it an ideal choice for interfacing between different voltage domains in digital systems.
