Hot-selling and scarce HEF4040BT 12-stage binary counter SOP16 spot stock

Product Descriptions

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 (O0 to O11). 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. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.

Product Applications

Some examples of applications for the HEF4040B are:

• Frequency dividing circuits

• Time delay circuits

• Control counters
