Philips Semiconductors Product specification 8-stage shift-and-store bus register 74HC/HCT4094 The data in each shift register stage is transferred to the storage register when the strobe input (STR) is HIGH. Data in the storage register appears at the outputs whenever the output enable input (OE) signal is HIGH. FEATURES • Output capability: standard • ICC category: MSI Two serial outputs (QS1 and QS2) are available for cascading a number of “4094” devices.

Philips Semiconductors Product specification 8-stage shift-and-store bus register 74HC/HCT4094 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.
