Philips Semiconductors Product specification 8-bit serial-in/parallel-out shift register 74HC/HCT164 Data is entered serially through one of two inputs (Dsa or Dsb); either input can be used as an active HIGH enable for data entry through the other input. Both inputs must be connected together or an unused input must be tied HIGH.

Philips Semiconductors Product specification 8-bit serial-in/parallel-out shift register 74HC/HCT164 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.
