SCLT3-8BQ7-TR

High speed digital input current limiter with digital filter

Input Voltage Min Volt-0.3
Input Voltage Max Volt30.0
ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameQFN-48L

The SCLT3 series is an octal industrial digital input IC which drastically reduces the power dissipation of the digital input modules. Its current-sinking inputs can be configured for Type 1, Type 2, or Type 3 inputs as per IEC 61131-2 with few external components.The SCLT3 series includes a serial...

Key features
  • Eight current-sinking digital inputs with serializer
  • Enables inputs to meet type 1, 2 and 3 characteristic of IEC 61131-2 standard
  • Adjustable and accurate input current limitation for low power and heat dissipation:
    • 2.35 mA typ for Type 1 and Type 3
  • Integrated glitch and debounce filter with selectable delay time: 20 µs to 3 ms for EMC robustness
  • 35 V reverse polarity capable
  • SPI-Compatible Serial Interface 8-bit
    • Optional 16-bit mode with parity check, and diagnostics (temperature alarm, voltage alarms)
  • Daisy-Chain SPI to reduce isolation channels
  • 5 V voltage regulator
  • Energyless Field-Side LED drivers for visual status indication
  • Operating ambient temperature range from -40 °C to 105 °C
  • Packages
    • HTSSOP-38 – 500 µm pitch
    • QFN-48L – 500 µm pitch
  • Complies with the following standards:
    • IEC 61000-4-2 level 4: ±15 kV (air discharge)
    • IEC 61000-4-2 level 4: ±8 kV (contact discharge)
