DESCRIPTION

The 74V CX16244 i s a low voltage CMOS 16 BIT BUS BUFFER (NON INVERTED) fabricated with sub-micron silicon gate and five-layer metal wiring

2

C

MOS technology. It is ideal for low power and very high s peed 1.8 to 3.6V applications; it can be interfaced to 3.6V signal environment for both inputs and outputs. Any nG BUFFERS. Output Enable input (nG

output con trol governs four BUS

) tied together gives full 16-bit operation. When nG

is LO W, the outputs are on. When nG is HIGH, the output are in high impedance state. This dev ice is designed to be used with 3 state memory address drivers, etc. All inputs and outputs are equipped with protection circuits against static discharge, givi ng them 2K V ESD immunity and transient excess voltage.
