Additional Details

The TC74LCX164245 features TTL-compatible inputs, allowing seamless integration with 5V TTL logic while operating at 3.3V. The dual enable controls (OEAB, OEBA) provide flexible direction control, allowing the device to act as either a transceiver from A to B or from B to A. The device provides a high output drive capability (±24 mA), ensuring reliable signal transmission across the bus. The low power consumption (ICC = 10 μA max) makes it suitable for portable applications. It is available in surface-mount packages for efficient board assembly. This transceiver is ideal for applications where high-speed bidirectional data transfer is required, such as memory interfaces and inter-processor communication.
