• Manufacturer: NXP Semiconductors

Philips Semiconductors
GENERAL DESCRIPTION
The LED-driver is a bipolar integrated circuit made in an
I
designed to drive four 7-segment LED displays with
decimal point by means of multiplexing between two pairs
of digits. It features an I
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
Note
1. The positive current is defined as the conventional current flow into a device (sink current).
