The HCC4060B (extended temperature range) and HCF4060B (intermediate temperature range) are monolithic integrated circuit, available in 16-lead dual in line plastic or ceramic package and plastic micropackage. The HCC/HCF4060B consist of an oscillator section and 14 ripple carry binary counter stages. The oscillator configuration allows design of either RC or crystal oscillator circuits. A RESET input is provided which reset the counter to the all 0's state and disables oscillator. A high level on the RESET line accmplishes the reset function. All counter stages are master slave flip-flops. The state of the counter is advanced one step in binary order on the negative transition of 1 (and 0). All inputs and outputs are fully buffered. Schmitt trigger action on the clock lin permits unlimited clock rise and fall time.
