Overview
The CD4094BE is an 8-stage serial shift register with a storage latch associated with each stage, designed and manufactured by Texas Instruments. This component is part of the 4000B series of CMOS devices and is used for serial-to-parallel data conversion. It features 3-state parallel outputs that can be connected directly to common bus lines, making it versatile for various applications. The device operates by shifting data on positive clock transitions and transferring data from the shift register to the storage register when the STROBE input is high. The OUTPUT-ENABLE signal controls the appearance of data at the outputs.
