6 / 7 page SN74HC4060Q1 14STAGE ASYNCHRONOUS BINARY COUNTER AND OSCILLATOR SCLS599 − NOVEMBER 2004 6 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 CONNECTING AN RC-OSCILLATOR CIRCUIT TO THE SN74HC4060 DEVICE The SN74HC4060 device consists of an oscillator section and 14 ripple-carry binary counter stages. The oscillator configuration allows design of either RC- or crystal-oscillator circuits. When an RC-oscillator circuit is implemented, two resistors and a capacitor are required. The components are attached to the terminals as shown: 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 R2 R1 C To determine the values of capacitance and resistance necessary to obtain a specific oscillator frequency (f), use this formula: f + 1 2(R1)(C) 0.405 R2 R1 )R2 ) 0.693 If R2 > > R1 (i.e., R2 = 10R1), the above formula simplifies to: f + 0.455 RC |
