0.25 Ordering number:ENN1369C Monolithic Digital IC LB1245 Active-Low Input Fluorescent Display Tube Driver Overview The LB1245 has been designed for interfacing low-level digital devices to fluorescent display tubes. Its 8-circuit independent Darlington output stage is used for digit and segment drivers. Equivalent pull-down resistors are built in ; externally connected resistors to prevent ghosts are no longer required. Output is activated when input voltages are at a low level, making the IC and ideal interface for Nchannel MOS devices. (VDD, VSS of IC can be made common to VDD, VSS of the LB1245.) Features • 8-channel independent Darlington driver. • Capable of driving digits or segments. • Built-in pull-down sink current.
