LB1240 Datasheet (Sanyo) - Fluorescent Display Tube Driver

LB1240, Fluorescent Display Tube Driver

Ordering number:ENN843E Monolithic Digital IC LB1240 Fluorescent Display Tube Driver Overview The LB1240 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 an ideal interface fo
