Abstract
An image sensor with a small circuit area is provided. In the image sensor, a TX decoder which generates transfer signals TX<3:0> includes a latch circuit. The latch circuit is set when a corresponding row group is selected and when a set signal is set to an “H” level, and is reset when a reset signal is set to an “L” level. The latch circuit serves also as a voltage level shift circuit which converts the “H” level of a signal from a first power supply voltage into a second power supply voltage. Therefore, plural row groups can be selected by setting plural latch circuits. It is not necessary to provide a voltage level shift circuit separately.
