74ACT244, OCTAL BUS BUFFER

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.

G control output governs four BUS BUFF
