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
