DESCRIPTION 74LCX162244 voltage CMOS BUFFER (NON-INVERTED) fabricated with sub-micron silicon gate double-layer metal wiring C2MOS technology. ideal power high speed 3.3V applications; interfaced signal environment both inputs outputs. output control governs four BUFFERS. Output Enable input (nG) tied together gives full 16-bit operation. When LOW, outputs When HIGH, output high impedance state. Active bus-hold circuitry provided hold unused floating data inputs valid logic level. This device designed used with state memory address drivers, etc. device circuits including series resistance outputs. These resistors permit reduce line noise high speed applications. inputs outputs equipped with protection circuits against static discharge, giving them immunity transient excess voltage.
