Overview
The LB1291 has been designed for interfacing between low
level digital devices and fluorescent display tubes. Its 8channel 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.
