Key Features
- Two serial data inputs (DSA and DSB) with the ability to use either input as an active HIGH enable for data entry through the other input.
- Eight parallel outputs (Q0 to Q7).
- Data is shifted on the LOW-to-HIGH transition of the clock input (CP).
- Asynchronous master reset (MR) to clear the register and force all outputs LOW.
- Inputs include clamp diodes to interface with voltages in excess of VCC.
- Wide supply voltage range from 1.0 V to 5.5 V, optimized for low-voltage applications.
- Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V.
- Low output ground bounce and output VOH undershoot.
- High ESD protection.
