STMicroelectronics M5482
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. This is a stress rating only and functional operation of the device at these or any other conditions in excess of those indicated in the operational sections of this specification is not implied.| Part No. | M5482 |
