Key Features
- Serial-in/Serial or Parallel-out Shift Register: The device features a serial input (D) and two serial outputs (QS1 and QS2) to enable cascading.
- Storage Register: Data in the shift register is transferred to the storage register when the STR input is HIGH.
- 3-State Outputs: Outputs appear at the outputs whenever the output enable input (OE) is HIGH. A LOW on OE causes the outputs to assume a high-impedance OFF-state.
- ESD Protection: Complies with ANSI/ESDA/JEDEC JS-001 class 2 (HBM) exceeding 2000 V and ANSI/ESDA/JEDEC JS-002 class C3 (CDM) exceeding 1000 V.
- Temperature Range: Specified from -40 °C to +125 °C.
- Low Power Dissipation: Designed for low power consumption.
Applications
- Automotive Electronics: Qualified to the AEC-Q100 standard, making it suitable for various automotive applications, including safety and efficiency improvements in e-mobility options.
- Industrial Automation: Used in industrial environments for applications such as motor drives, collaborative robots (cobots), and industrial equipment.
- Consumer Electronics: Finds use in various consumer electronic devices requiring serial-to-parallel data conversion and remote control holding registers.
