74HC/HCT4040; 12-stage binary ripple counter
Description: The 74HC4040D is a 12-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve parallel outputs (Q0 to Q11). Features: High speed: tpd = 12 ns (typical) at VCC = 5 V Low power dissipation: ICC = 4 μA (maximum) at Ta = 25 °C High noise immunity: VNIH = VNIL = 28 % VCC (min) Balanced propagation delays: tPLH ≈ tPHL Symmetrical output impedance: IOH = IOL (max) = 4 mA (at VCC = 5 V) High output current: IOH = -IOL = 8 mA (min) (at VCC = 5 V) Low input current: II = 1 μA (max) Wide operating voltage range: VCC (opr) = 2 V to 6 V Applications: Frequency division Clock and timing control Pulse generation Sequential timing Event counting
