HD74AC164/HD74ACT164
Serial-In, Parallel-Out Shift Register
Description
The HD74AC164/HD74ACT164 is a high-speed 8-bit serial-in/parallel-out shift register. Serial data is
entered through a 2-input AND gate synchronous with the Low-to-High transition of the clock. The device
features an asynchronous Master Reset which clears the register, setting all outputs Low independent of the
clock.

Functional Description
The HD74AC164/HD74ACT164 is an edge-triggered 8-bit shift register with serial data entry and an
output from each of the eight stages. Data is entered serially through one of two inputs (A or B); either of
these inputs can be used as an active High Enable for data entry through the other inputs. An unused input
must be tied High.
Each Low-to-High transition on the Clock (CP) input shifts data one place to the right and enters into Q0
the logical AND of the two data inputs (A•B) that existed before the rising clock edge. A Low level on the
Master Reset (MR) input overrides all other inputs and clears the register asynchronously, forcing all Q
outputs Low.
