Toshiba T3084
Integrated Circuit

This IC is used as a driver for vacuum flourescent displays in early LSI calculators.
Period: 1972.
Source of Data: Data for this device was derived from reverse engineering of a Toshiba BC-0802.
Technology: Probably two bipolar transistors per buffer.
Supply Voltage: No direct connection of the supply voltage to the IC is required. However it was used in environments where the logic supply was -15V.
Logic: Logic levels are GND and -15V. Outputs are open-collector.
Packaging: Standard 16-pin DIP.
  • The third connection on each buffer is for an external bias resistor.
  • IC package as viewed from above.
