- **oe_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): Pin connected to SN74HC595 OE pin
- **sr_count** (*Optional*, int): Number of daisy-chained shift registers, up-to 256. Defaults to ``1``.
Pin configuration variables:
****************************
- **sn74hc595** (**Required**, :ref:`config-id`): The id of the SN74HC595 component the pin belongs to.
- **number** (**Required**, int): The pin number.
- **inverted** (*Optional*, boolean): If all written values should be treated as inverted.
Defaults to ``false``.

************************
- **id** (**Required**, :ref:`config-id`): The id to use for this SN74HC595 component.
- **spi_id** (**Required**, :ref:`SPI Bus Schema <spi>`): The SPI bus to use. This will automatically be set to the ID of the SPI bus if there is only one.
- **type** (**Required**, string): Must be ``spi``.
