It features separate clock inputs for the shift register (CP) and storage register (STR), allowing new data to be shifted in without disturbing the current output state. The tri-state outputs (OE control) enable bus-oriented applications, and the serial output (Qs) provides cascading capability for unlimited output expansion. Operating from 3V to 15V, it is compatible with both CMOS and TTL logic levels.","working_principle":"The HEF4094BT653 combines a serial shift register with parallel output latches and tri-state buffers. **Shift Register**: Serial data on the D input is clocked into the 8-bit shift register on each rising edge of CP (shift clock). The Qs output provides the serial overflow for cascading to the next device. **Storage Register**: On the rising edge of STR (strobe), the current shift register contents are transferred to the 8-bit storage\/latch register. This two-stage architecture allows simultaneous update of all outputs. **Output Enable**: The OE input controls the tri-state output buffers. When OE is HIGH, the outputs are active; when LOW, all outputs are high-impedance. This enables direct connection to data buses. **Cascading**: The Qs serial output connects to the D input of the next device, allowing unlimited cascading. The Qs output is not tri-stated and is always active, enabling the shift clock to propagate data through the entire chain.","pin_description":"
