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. Data is available at QS1 on the positive-going clock edges to allow high-speed operation in cascaded systems in which the clock rise time is fast. The same serial information is available at QS2 on the next negative-going clock edge and is for cascading "4094" devices when the clock rise time is slow. GENERAL DESCRIPTION The 74HC/HCT4094 are high-speed Si-gate CMOS devices and are pin compatible with the "4094" of the "4000B" series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT4094 are 8-stage serial shift registers having a storage latch associated with each stage for strobing data from the serial input (D) to the parallel buffered 3-state outputs (QP0 to QP7). The parallel outputs may be connected directly to common bus lines. Data is shifted on the positive-going clock (CP) transitions.

CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD x VCC2 x fi + (CL x VCC2 x fo) where: fi = input frequency in MHz fo = output frequency in MHz (CL x VCC2 x fo) = sum of outputs CL = output load capacitance in pF VCC = supply voltage in V 2.
