SAA1064

INTEGRATED CIRCUITS DATA SHEET SAA1064 4-digit LED-driver with I2C-Bus interface Product specification File under Integrated Circuits, IC01 February 1991 Philips Semiconductors Product specification 4-digit LED-driver with I2C-Bus interface 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. QUICK REFERENCE DATA PARAMETER Supply voltage Supply current all outputs OFF Total power dissipation 24-lead DIL (SOT101B) 24-lead DIL SO (SOT137A) Operating ambient temperature range Note 1. The positive current is defined as the conventional current flow into a device (sink current).
