74ACT125 Datasheet (Fairchild Semiconductor)

74ACT125, Quad Buffer

The ACT125 is an high-speed CMOS QUAD BUS BUFFERS fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

It is ideal for low power applications maintaining high speed operation similar to PIN CONNECTION AND IEC LOGIC SYMBOLS May 1997 1/8 74ACT125 INPUT AND OUTPUT
