The MC74LCX16373DTG is part of ON Semiconductor's advanced low power, low voltage (2.5V) CMOS logic family. This 16-bit Buffer/Line Driver/Bus Transceiver is designed to provide high-performance fail-safe signal transmission between two buses. It is characterized by a low on-state impedance, which allows very fast switching between the two buses without signal distortion, making it ideal for multiplexed bus and memory applications. It has active bus hold circuitry that maintains data on the bus when no access is occurring, eliminating the need for external pull-up/pull-down resistors. With a maximum clock frequency of 80MHz and a total supply current of 2.4mA, it is perfect for fast, low-power applications.
