Description:

The HD7279A-WP is a versatile serial interface, 8-digit, common-anode LED driver IC. It simplifies driving multiple LEDs by providing a serial interface and built-in decoding logic, reducing the number of pins required compared to parallel interfaces. The HD7279A-WP can also be connected to a keypad matrix with up to 8 keys, offering a cost-effective solution for combined LED display and button control functionality in a single chip.

Key Features:

  • Drives up to 8 common-anode LEDs for numeric or alphanumeric displays
  • Serial interface (SPI compatible) for efficient data transfer
  • Built-in scanning circuitry eliminates the need for external decoders
  • Optional keypad matrix interface for up to 8 keys (reduces component count for combined display and button control)
  • Wide operating voltage range (typically 5V to 15V)
  • Low power consumption

Technical Specifications:

  • Package Type: SOP-16
  • Input Voltage: 5V to 15V (typical)
  • Output Current:10mA to 20mA.
  • Serial Interface: SPI compatible
  • Keypad Matrix: Up to 8×1 (8 rows, 1 column)
  • Operating Temperature Range: 0°C to +70°C

Applications:

  • LED displays for clocks, timers, meters, and other electronic devices
  • Simple control panels with LED readouts and button inputs
  • Educational and hobbyist projects with LED displays
