Key Features
- Gated Serial Data Inputs: Data can be entered serially through two inputs (DSA and DSB), with either input capable of acting as an active HIGH enable for data entry through the other input.
- Asynchronous Master Reset: A LOW on the master reset input (MR) clears the register and forces all outputs LOW, independently of other inputs.
- Wide Supply Voltage Range: Operates from 1.0 V to 5.5 V, optimized for low-voltage applications between 1.0 V and 3.6 V.
- ESD Protection: High ESD protection levels, exceeding 2000 V for HBM and 1000 V for CDM.
- Low Output Ground Bounce and Undershoot: Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V and Tamb = 25 °C, and typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V and Tamb = 25 °C.
