The NE587 is a latch/decoder/driver for 7-segment common anode LED displays. The NE587 has a programmable current output up to 50mA which is essentially independent of output voltage, power supply voltage, and temperature. The data (BCD) inputs and LE (latch enable) input are low-loading so that they are compatible with any data bus system.The 7-segment decoding is implemented with a ROM so that alternative fonts can be made available.
