What this 8-bit bus register does on your board
The Texas Instruments CD4094BE is an 8-stage serial-to-parallel shift register with tri-state output latches, part of the 4000B CMOS logic family. It takes serial data in on the DATA input and shifts it through eight bits on each positive clock edge; the latched parallel outputs appear on Q1 through Q8 when the output-enable (OE) pin is high. The tri-state outputs let you share the bus with other devices — pull OE low and the outputs go high-impedance, not a fixed logic level. This matters on a multiplexed data bus or when driving a common LED anode row where you need to float the line between updates.
Supply range and temperature — why the 4000B still gets specified
The CD4094BE runs on any supply from 3V to 18V. The operating temperature range is -55°C to 125°C.
Package and mounting — through-hole for serviceability
Supplied in a 16-pin plastic DIP (0.300-inch body, 7.62 mm row spacing), the CD4094BE is a through-hole part.
Lifecycle and sourcing
Texas Instruments lists the CD4094BE as Active and ROHS3 compliant. No last-time-buy notice, no NRND flag. For a BOM line that needs a 4000B shift register, this is the direct order code — no substitution risk.
