The 74ALVCH16244 is a low voltage CMOS 16 BIT BUS BUFFER (NON INVERTED) fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. It is ideal for low power and very high speed 1.65 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 enabled. When nG is HIGH, the output are in high impedance state.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level. This device is designed to be used with 3 state memory address drivers, etc.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
