HD74HC4060
14-stage Binary Counter
Description
The HD74HC4060 is a 14 stage counter, this device increments on the falling edge (negative transition) of the input clock, and all their outputs are reset to a low level by applying a logical high on their reset input. The HD74HC4060 also has two additional inputs to enable easy connection of either an RC or crystal oscillator.
Features
• • • • • High Speed Operation: tpd (Clock to Q4) = 41.5 ns typ (C L = 50 pF) High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
