Key Features
- Serial to Parallel Function: Data is entered serially through two inputs (DSA and DSB) and output in parallel through eight outputs (Q0 to Q7).
- Gated Serial Data Inputs: Either input can be used 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.
- Input Clamp Diodes: Allows the use of current limiting resistors to interface inputs to voltages in excess of VCC.
- Low Power Dissipation: CMOS technology ensures low power consumption.
- High Noise Immunity: Provides robust operation in noisy environments.
- Compliance with JEDEC Standards: Meets JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V) standards.
Applications
- Digital Circuit Design: Suitable for a wide range of digital circuit applications requiring serial to parallel data conversion.
- Embedded Systems: Used in embedded systems where serial data needs to be converted to parallel format for processing or display.
