DESCRIPTION

The 74LCX240 is a low voltage CMOS OCTAL BUS BUFFER 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. It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption.
