It features separate clocks for the shift and storage registers, providing flexible data management. The device has a serial data input (D) and two serial outputs (QS1 and QS2) that enable daisy-chain cascading of multiple devices. QS1 outputs data on the rising clock edge for fast cascading, while QS2 outputs on the falling edge for slow-edge compatibility. Data is shifted through the register on LOW-to-HIGH transitions of the clock (CP) input, and transferred to the storage register when the strobe (STR) input is HIGH. The 3-state parallel outputs are controlled by the output enable (OE) pin, allowing connection to shared bus lines. Operating from 2V to 6V with CMOS input levels, the 74HC4094D is specified for -40 to 125 C in a 16-pin SOIC package.","working_principle":"The 74HC4094D operates as a serial-to-parallel converter with intermediate storage. Key subsystems include: (1) 8-Stage Shift Register - on each rising edge of CP, data at the D input is shifted into the first stage, and existing data shifts one position toward the last stage; (2) Storage Register - when STR is HIGH, the contents of the shift register are transferred to the storage register; this allows the shift register to be loaded while the storage register holds the previous data on the outputs; (3) 3-State Output Buffers - when OE is HIGH, the storage register data appears on QP0-QP7; when OE is LOW, all outputs are in high-impedance state; (4) Cascading Outputs - QS1 provides data from the last shift register stage on the rising CP edge for fast-edge cascading; QS2 provides the same data on the falling CP edge for slow-edge cascading; (5) Input Clamp Diodes - protect inputs from voltage excursions beyond the supply rails.","pin_description":"
