DESCRIPTION The 74VHC16244 is an advanced high-speed CMOS 16-BIT BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology. Any nG output control governs four BUS BUFFERS. Output Enable inputs (nG) tied together give full 16 bit operation. When nG is LOW, the outputs are enabled. When nG is HIGH, the output are in high impedance state. The device is designed to be used with 3-state memory address drivers, etc. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
