HEF4040BT: 12-stage binary ripple counter
The HEF4040B is a 12-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered outputs (Q0 to Q11). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of CP. Each counter stage is a static toggle flip-flop. The clock input is highly tolerant of slow rise and fall times due to its Schmitt trigger action.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS(usually ground). Unused inputs must be connected to VDD, VSS, or another input.
