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. W hen the input v oltage is at a high level,
the output gets activated.
Features
• 8-channel independent Darlington driver.
• Capable of driving digits or segments.
• On-chip sink current circuit for pull-down.
• 55V/30mA rating.
