General description
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 co...
