DESCRIPTION
The 74ALS164 is an 8-bit edge-triggered shift register with serial data entry and an output from each of the eight stages. Data is entered serially through one of two inputs (Dsa, Dsb); either input can be used as an active-high enable for data entry through the other input. Both inputs must be connected together or an unused input must be tied High.

FEATURES
• Gated serial data inputs
• Typical shift frequency of 75MHz
• Asynchronous master reset
• Buffered clock and data inputs
• Fully synchronous data transfer
