INTEGRATED CIRCUITS 74LV4060 14-stage binary ripple counter with oscillator Product specification 1998 Jun 23 Philips Semiconductors Philips Semiconductors Product specification 14-stage binary ripple counter with oscillator 74LV4060 FEATURES Wide operating voltage: 1.0 to 5.5 V Optimized for Low Voltage applications: 1.0 to 3.6 V Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, Tamb All active components on chip RC or crystal oscillator configuration Output capability: standard (except for RTC and CTC) ICC category: MSI = 25°C. Tamb = 25°C. APPLICATIONS Control Counters Timers Frequency Dividers Time-delay circuits DESCRIPTION The 74LV4060 is a low-voltage Si-gate CMOS device and is pin and function compatible with the 74HC/HCT4060. The 74LV4060 is a 14-stage ripple-carry counter/divider and oscillator with three oscillator terminals (RS, RTC and CTC), ten buffered outputs (Q3 to Q9 and Q11 to Q13) and an overriding asynchronous master reset (MR). The oscillator configuration allows design of either RC or crystal oscillator circuits. The oscillator may be replaced by an external clock signal at input RS. In this case, keep the oscillator pins (RTC and CTC) floating. The counter advances on the negative-going transition of RS. A HIGH level on MR resets the counter (Q3 to Q9 and Q11 to Q13 = LOW), independent of the other in……
