The UT54ACS299E is an 8-bit universal shift/storage register featuring multiplexed I/O ports to achieve full 8-bit data handling in a single 20-pin package. Two function-select (S0, S1) inputs and two output enable (OE1, OE2) inputs can be used to choose the mode of operation listed in the function table. Additional outputs are provided for flip flops Q0, Q7 to allow easy serial cascading. A separate active low master reset (MR) is used to reset the register, overriding the select and CP inp...
