The 74ACT3301 is a crystal controlled CMOS

oscillator requiring a minimum of external components

and is designed for Clock Generation and Support

applications up to 110 MHz. The device is highly

versatile, providing selectable output divide ratios,

multiple crystal drive levels and selectable rise and fall

timing options. The circuit is designed to operate over

a wide frequency range using fundamental model or

overtone crystals. The device is a direct electrical and

mechanical replacement for the obsolete 74ACT3301

produced by National Semiconductor.
