HEF4060B

Pinout




Description

  The HEF4060B is a 14-stage ripple-carry binary counter/divider and oscillator with three oscillator terminals (RS, R TC and C TC ), ten buffered outputs (O 3 to O 9 and O 11 to O 13 )and an overriding asynchronous master reset input (MR). The oscillator configuration of HEF4060B allows design of either RC or crystal oscillator circuits. The oscillator may be replaced by an external clock signal at input RS. The HEF4060B counter advances on the negative-going transition of RS. A HIGH level on MR resets the counter (O 3 to O 9 and O 11 to O 13 = LOW), independent of other input conditions.Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.
