PDF covering the HEF4094B, an 8-stage shift-and-store bus register from the 4000-series CMOS logic family, listed as a schematic and 199 KB in size. Expect pinout, logic diagram, timing for data, clock and strobe inputs, and electrical limits. Repair use includes tracing serial data lines to displays, LED drivers or relay banks, probing clock and strobe signals with a scope and confirming output enable behaviour. The file opens in any PDF reader; match the package and supply voltage of the fitted part before swapping it.
