LB1290
SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Overview
The LB1290 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.

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.
