SAA1064 4-digit LED-driver with I2C-Bus interfaceFor Common Anode led displays
Supply Voltage 5 V
Dynamic mode: 4 digits, Static mode: 2 digits
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 I
2C-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.
