74F164A Serial-In, Parallel-Out Shift Register October 1989 Revised October 2000 74F164A Serial-In, Parallel-Out Shift Register General Description The 74F164A 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. The 74F164A is a faster version of the 74F164. Features s Typical shift frequency of 90 MHz s Asynchronous Master Reset s Gated serial data input s Fully synchronous data transfers s 74F164A is a faster version of the 74F164 Ordering Code: Order Number 74F164ASC 74F164ASJ 74F164APC Package Number M14A M14D N14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150 Narrow 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.

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 input. 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.
