DATA SHEET
MOS INTEGRATED CIRCUIT
µPD6345
8 BIT SERIAL IN/PARALLEL OUT DRIVER
The µPD6345 is a monolithic Bi-CMOS integrated Circuit designed to drive LED, Solenoid and Relay.
This device consists of an 8-bit shift register, latch and buffer with high voltage N-P-N Transistors (Open Collector).
Data is serially loaded into shift register on the positive-going transition of the clock. Parallel data is transferred to
the output buffers through the 8-bit latch while the latch enable input is high and latched when the latch enable is low.
When the output enable input is low, all outputs are off (High Impedance).
FEATURES
• High Speed Serially-shifted Data Input.
• Latches on all driver Outputs.
• 40 V Output Voltage Rating.
• 60 mA Output Sink Current.
• Built in power supply voltage detection circuit.
• Capable of connection to cascade additional device.
• Wide Operating Temperature Range: –40 to +85 °C
• Bi-CMOS STRUCTURE

this document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property
rights of third parties by or arising from use of a device described herein or any other liability arising from use
of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other
intellectual property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
