The 74LV4094D,118 from Nexperia is an 8-bit shift register with output latches and 3-state outputs. It features a cascade output (QS) for daisy-chaining multiple devices, enabling serial-to-parallel conversion for LED displays and I\/O expansion with minimal pin count.<\/p>\n

Serial data is shifted in through D input on each rising STR clock edge. After 8 bits are loaded, the STROBE input transfers shift register data to the output latches. OE (output enable) controls tri-state outputs. QS cascade output provides the shift register overflow for connecting to the D input of the next device in the chain.<\/p>\n
