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. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf = 6 ns 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. 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. APPLICATIONS * Serial-to-parallel data conversion * Remote control holding register TYPICAL SYMBOL tPHL/ tPLH PARAMETER propagation delay CP to QS1 CP to QS2 CP to QPn STR to QPn fmax CI CPD Notes 1. 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.
