Description
The 54VCXH162244 is a low voltage CMOS 16-bit bus buffer (non inverted) fabricated with submicron silicon gate and five-layer metal wiring C²MOS technology.
It is ideal for low power and very high speed 1.65 to 3.6 V applications; it can be interfaced to 3.6 V signal environment for both inputs and outputs. Any nG output control governs four BUS buffers. Output enable input (nG) tied together gives full 16bit 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 26 Ω 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 2 kV ESD immunity and transient excess voltage.

Maximum ratings
Stressing the device above the rating listed in the “absolute maximum ratings” table may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
