Product specification
14-stage binary ripple counter with oscillator
74HC/HCT4060
Notes
1. The value of additional quiescent supply current (∆ICC) for a unit load of 1 is given here.
To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below.
2. Only input MR (pin 12) has TTL input switching levels for the HCT versions.
