8-stage shift-and-store bus register in 74HC logic
The CD74HC4094M96G3 is an 8-bit serial-to-parallel shift register from the 74HC family, with a storage register and tri-state output stage. It accepts serial data on a single input and presents it in parallel on eight outputs, with the storage register isolating the output latch from the shift register during data entry.
The ROHS3 compliance covers RoHS exemption requirements through the latest directive.
Where it fits — serial expansion and bus isolation
The tri-state output lets multiple registers share a common data bus without contention, which is the usual use case for driving LED arrays, relay banks, or parallel DACs from a microcontroller with limited GPIO. The 8-bit width per element matches the most common expansion ratio for SPI or bit-banged serial links. The 16-SOIC footprint is a standard narrow-body package that fits existing PCB layouts for 74HC4094-class parts.
