Working Principles

The M74HC4094B1R operates based on the principle of serial-in, parallel-out (SIPO) shift registers. It receives serial data through the DS pin and shifts it into an internal shift register upon each clock pulse at the CP input. The parallel data is then available at the QA-QH outputs. The storage register clock (SHCP) and shift register clock (STCP) inputs control the transfer of data between the shift register and the storage register.

Detailed Application Field Plans

The M74HC4094B1R finds application in various digital systems, including but not limited to: - LED matrix displays - Multiplexed seven-segment displays - Data acquisition systems - Serial data communication interfaces - Address decoding circuits - Control signal generation circuits
