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 N-
channel MOS devices. (VDD, VSS of IC can be made com-
mon to VDD, VSS of the LB1245.)
Features
• 8-channel independent Darlington driver.
• Capable of driving digits or segments.
• Built-in pull-down sink current.
• Rated at 55V/30mA

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer's
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer's products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
