Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained

Monolithic Digital IC
Fluorescent Display Tube Driver
Ordering number:ENN1173C
LB1241
SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
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 lev el, making the IC and ideal interface for Nchannel 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 pre venting ghost
effectively.

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.
