SAA1064 4-digit LED-driver with I2C-Bus interface

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.
