ON Semiconductor MC74LCX245DTR2 Octal Bidirectional Transceiver
The MC74LCX245DTR2 from ON Semiconductor is a high-performance, octal bidirectional transceiver that is designed to facilitate the transfer of data between two buses of differing voltage levels. This integrated circuit is a part of the LCX family, which is known for its low-voltage operation and high-speed interfacing capabilities.
This transceiver features an 8-bit non-inverting bus transceiver with 3-state outputs, which makes it ideal for bidirectional asynchronous communication between data buses. The device allows data transmission from the A bus to the B bus and vice versa, depending on the logic level at the direction control (DIR) input. The output enable (OE) input can be used to disable the device so that the buses are effectively isolated.
The MC74LCX245DTR2 operates at a voltage range of 2.3V to 3.6V, which allows for use in low-voltage applications such as interfacing with the 3.3V logic levels commonly found in modern digital systems. It is also 5V tolerant on input pins to accommodate interfacing with traditional 5V systems without the risk of damage.
Featuring a high drive capability and low static power consumption, the MC74LCX245DTR2 is optimized for power-sensitive designs. Its power-off high impedance inputs and outputs ensure that the device remains in a high-impedance state when powered down, thereby minimizing power consumption.
The device is provided in a TSSOP-20 package, which is a space-saving package suitable for surface mount technology (SMT). This makes the MC74LCX245DTR2 a perfect choice for compact and high-density electronic assemblies.
ON Semiconductor's commitment to quality ensures that the MC74LCX245DTR2 meets the stringent requirements for industrial and commercial temperature ranges, making it a reliable choice for a wide range of applications, including computing, networking, telecommunications, and consumer electronics.
Overall, the MC74LCX245DTR2 transceiver is a versatile component that offers designers the flexibility to interface between different voltage levels while maintaining signal integrity and speed, all within a compact, power-efficient package.
