M5480 Datasheet PDF - STMicroelectronics

DESCRIPTION
The M5480 is a monolithic MOS integrated circuit produced with a N-channel silicon gate technology. It utilizes the M5451 die packaged in a 28-pin plastic package making it ideal for a 3 1/2 digit dispaly. A single pin controls the LED dispaly bright ness by setting a reference current through a vari able resistor connected either to VDD or to a separate supply of 13.2V maximum.
The M5480 is a pin-to-pin replacement of the NSMM 5480.
