M5482B7(1993) Datasheet PDF - STMicroelectronics

DESCRIPTION
The M5482 is a monolithic MOS integrated circuit produced with an N-channel silicon gate technology. It utilizes the M5451 die packaged in a 20-pin plastic package copper frame, making it ideal for a 2-digit display. A single pin controls the LED display brightness by setting a reference current through a variable resistor connected either to VDD or to a separate supply of 13.2V maximum.
