Parallel input serial output shift register verilog code serial#

The active-low asynchronous Reset overrides the Clock and Serial Data inputs. Data is entered on each rising edge of the clock. Two serial data inputs, A1 and A2, are provided so that one input may be used as a data enable. The IN74AC164 is an 8-bit, serial-input to parallel-output shift register. The device inputs are compatible with standard CMOS outputs with pullup resistors, they are compatible with LS/ALS outputs.

Both inputs must be connected together or an unused input must be tied HIGH.ĭata shifts one place to the right on each LOW-to-HIGH transition of the clock input (CP) and enters into Q0, which is the logical AND-function of the two data inputs (DSA and DSB) that existed one set-up time prior to the rising clock edge.Ī LOW on the master reset input (MR) overrides all other inputs and clears the register asynchronously, forcing all outputs LOW.

Data is entered serially through one of two inputs (DSA or DSB) and either input can be used as an active HIGH enable for data entry through the other input. The 74LV164 is an 8-bit edge-triggered shift register with serial data entry and an output from each of the eight stages. The 74LV164 is a low-voltage, Si-gate CMOS device and is pin and function compatible with the 74HC164 and 74HCT164. 74LV164DB: 8-bit serial-in/parallel-out shift register
