Overview
The LB1241 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 N-
channel MOS devices.
Features
• 8 circuit independent Darlington driver.
• Capable of driving digits or segments.
• Built-in pull-down sink current.
• Rated at 45V/30mA
• Large pull-down current and capable of preventing ghost
