Key Features
- Asynchronous 8-bit Parallel Load: Data from D0 to D7 can be loaded into the shift register asynchronously when the parallel load input (PL) is LOW.
- Synchronous Serial Input: Data enters the register serially at the DS input when PL is HIGH.
- Complementary Serial Outputs: The device features two complementary serial outputs (Q7 and Q7').
- Input Levels: Compatible with TTL input levels.
- ESD Protection: High ESD protection (HBM JESD22-A114F exceeds 2000 V, MM JESD22-A115-A exceeds 200 V).
- Operating Temperature Range: Specified from -40 °C to +125 °C).
- Overvoltage Tolerance: Inputs are overvoltage tolerant up to 15 V, enabling use in level shifting applications).
Applications
- Parallel-to-Serial Data Conversion: Ideal for converting parallel data into a serial output, which is useful in various digital communication and data processing systems).
- Digital Circuit Design: Used in the design of digital circuits where data needs to be shifted or converted between parallel and serial formats.
- Embedded Systems: Can be integrated into embedded systems requiring efficient data handling and conversion.
