The LB1290 from Telefunken is a monolithic digital IC featuring an 8-channel independent Darlington driver array. This component is designed for interfacing low-level digital devices with fluorescent display tubes, making it suitable for driving digits or segments.
Key electrical specifications include a maximum output current of 30mA and a maximum power dissipation of 1.3W. The device operates within a supply voltage range of 4.7V to 5.5V and has an operating temperature range of -20°C to +75°C. The absolute maximum supply voltage is rated at +0.55V to -3.0V.
The LB1290 is supplied in a DIP18 package. Its design incorporates an on-chip sink current circuit for pull-down, eliminating the need for externally connected resistors for ghost prevention. When the input voltage is at a high level, the output becomes activated.
