Overview

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.

Key Features
