The 74HC4060D is a high-speed Si-gate CMOS device and is pin compatible with the HEF4060. The 74HC4060D are 14-stage ripple-carry counter/dividers and oscillators 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 other 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 other input conditions. In the HCT version, the MR input is TTL compatible, but the RS input has CMOS input switching levels and can be driven by a TTL output by using a pull-up resistor to VCC. 74HC4060D Features: All active components on chip RC or crystal oscillator configuration Complies with JEDEC standard no. 7 A ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from -40 °C to +85 °C and from -40 °C to +125 °C Applications: Control counters Timers Frequency dividers Time-delay circuits
