Description

The 74LCX16244A is a low voltage CMOS 16-BIT BUS BUFFER (NON-INVERTED) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs and outputs.

Any nG output control governs four BUS BUFFERS. Output Enable input (nG) of the 74LCX16244A 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.

The 74LCX16244A is designed to be used with 3 state memory address drivers, etc.

It has better speed performance at 3.3V than 5V LSTTL family combined with the true CMOS low power consumption.

All inputs and outputs of the 74LCX16244A are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
