74ACT244T

具有三态输出非反相八路总线缓冲器 OCTAL BUS BUFFER WITH 3 STATE OUTPUTS NON INVERTED

DESCRIPTION

The ACT244 is an advanced CMOS OCTAL BUS BUFFER 3-STATE fabricated with sub-micron

silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power applications

mantaining high speed operation similar to equivalent Bipolar Schottky TTL.
