GENERAL DESCRIPTION

The LED-driver is a bipolar integrated circuit made in an I2L compatible 18 volts process. The circuit is especially

designed to drive four 7-segment LED displays with decimal point by means of multiplexing between two pairs

of digits.

It features an I2C-Bus slave transceiver interface with the possibility to program four different SLAVE

ADDRESSES, a POWER RESET flag, 16 current sink OUTPUTS, controllable by software up to 21 mA, two

multiplex drive outputs for common anode segments, an on-chip multiplex oscillator, control bits to select static,

dynamic and blank mode, and one bit for segment test.
