54LS164 DM54LS164 DM74LS164 8-Bit Serial In Parallel Out Shift Registers June 1989 54LS164 DM54LS164 DM74LS164 8-Bit Serial In Parallel Out Shift Registers General Description These 8-bit shift registers feature gated serial inputs and an asynchronous clear A low logic level at either input inhibits entry of the new data and resets the first flip-flop to the low level at the next clock pulse thus providing plete control over ining data A high logic level on either input enables the other input which will then determine the state of the first flip-flop Data at the serial inputs may be changed while the clock is high or low but only information meeting the setup and hold time...
