Image sensor pixels may receive row control signals for row driver circuitry. The row driver circuitry may include a plurality of row driver circuits each of which is capable of outputting row control signals at more than two power supply voltage levels. A row driver circuit may include only two level shifting circuits. A first level shifting circuit may control a first pull-up path operable to drive the row driver output to a first power supply voltage level and may also control a second pull-up path operable to drive the row driver output to a second power supply voltage level. A second level shifting circuit may control a first pull-down path operable to drive the row driver output to a third power supply voltage level and may also control a second pull-down path operable to drive the row driver output to a fourth power supply voltage level.
