Philips Semiconductors Product specification 12-stage binary ripple counter 74HC/HCT4040 (Q0 to Q11). The counter advances on the HIGH-to-LOW transition of CP. FEATURES • Output capability: standard A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP. • ICC category: MSI Each counter stage is a static toggle flip-flop. GENERAL DESCRIPTION The 74HC/HCT4040 are high-speed Si-gate CMOS devices and are pin compatible with “4040” of the “4000B” series.

Philips Semiconductors Product specification 12-stage binary ripple counter 74HC/HCT4040 DC CHARACTERISTICS FOR 74HCT For the DC characteristics see “74HC/HCT/HCU/HCMOS Logic Family Specifications”. Output capability: standard ICC category: MSI Note to HCT types The value of additional quiescent supply current (∆ICC) for a unit load of 1 is given in the family specifications. To determine ∆ICC per input, multiply this value by the unit load coefficient shown in the table below.
