Document Type and Number:
Japanese Patent JP2004140752
Kind Code:
A
Abstract:
To provide a parallel-serial circuit that is constituted by shift register IC's and performs parallel-serial conversion to a switch signal where a shift register IC to which no switch signal is input is left unmounted.
When a shift register IC 300 on a prestage in cascade connection with a shift register IC 200 is left unmounted, a serial input terminal SI of the shift register IC 200 and a power source 600 is connected by connection means 500 to fix the potential of the serial input terminal SI of the shift register IC 200 at a high level.
