It is ideal for low power and very high speed 2.3 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. Any nG output control governs four BUS BUFFERS. Output Enable input (nG) tied together gives full 16-bit operation. When nG is LOW, the outputs are on. When nG is HIGH, the output are in high impedance state. This device is designed to be used with 3 state memory address drivers, etc. Bus hold on data inputs is provided in order to eliminate the need for external pull-up or pull-down resistor. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. 74VCXH16244 LOW VOLTAGE CMOS 16-BIT BUS BUFFER (3-STATE INV.)
