DESCRIPTION
The 74VCXH162240 is a low voltage CMOS 16 BIT BUS BUFFER (INVERTED) fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. 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.
The device circuits is including 26Ω series resistance in the outputs. These resistors permit to reduce line noise in high speed applications. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
