STLED316S - Serial-interfaced 6-digit LED controller

Description

The STLED316S is a compact LED controller and driver that interface microprocessors to LED displays through a serial 3-wire interface.

It drives LED connected in common anode configuration.

Features

  • LED driver with 14 outputs (8 segments/6 digits).
  • 40 mA load current capability for each segment.
  • Output pins connected directly to the LEDs or can be open-drain.
  • Key-scanning (8 x 2 matrix).
  • Low power consumption in standby mode.
  • 3-wire serial bus interface (CLK, STB, DIN/DOUT).
  • 8-step dimming circuit to control the overall display brightness.
  • Single external resistor for output current setting.
  • Inputs with Schmitt trigger give superior noise immun.
