All counter stages are master-slave flip-flops. Supports wide input voltage ranges from \u003cstrong\u003e3V to 18V\u003c\/strong\u003e. The maximum input current at 18V is 1uA whereas 100nA at 18V and 25°C.\u003c\/p\u003e\u003cp\u003eAll counter stages are \u003cstrong\u003emaster-slave flip-flops\u003c\/strong\u003e. The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets the counter to its all-zeros state. \u003cstrong\u003eSchmitt trigger\u003c\/strong\u003e action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered. 16 Pin DIP available in hermetic dual-in-line ceramic package. \u003c\/p\u003e\u003cp\u003eWe also have  with similar features.
