RS4094XS16

The RS4094 is an 8-bit serial-in/serial-or-parallel-out shift register with storage registers and three-state outputs. The shift register and storage register each have independent clocks. The device features one serial input (D) and two serial outputs (QS1 and QS2) for cascading applications. Data is shifted on the low-to-high transition of the CP input. Data is available at QS1 on the low-to-high transition of CP for cascading when clock edges are fast. The same data is available at QS2 on the next high-to-low transition of CP for cascading when clock edges are slow. When the STR input is high, data in the shift register is transferred to the storage register. Data in the storage register appears at the outputs as long as the output enable input (OE) is high. When OE is low, the outputs enter a high-impedance off-state. Operation of the OE input does not affect the register state. The device is available in a green SOP16 package with an operating temperature range of -40℃ to +125℃.
