DATA SHEET

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.
