Monolithic Digital IC
LB1290
8-Channel Driver Array
Overview
The LB1290 has been designed for interfacing between low
level digital devices and fluorescent display tubes. Its 8-
channel independent Darlington output stage is used for
digit or segment drivers. Also, with pull-down equivalent
resistors, no externally connected resistors are required for
ghost prevention. When the input voltage is at a high level,
the output gets activated.
