Dual SPI chip select with AVR SS

I am trying to forward the SS (top IO) from an AVR to one of two SPI devices with a pin used for addressing (bottom IO). LED's are the Not Chip Select (!CS) input of an SPI device.

An AVR SS is active low, and this fits with the SPI slave !CS input.   

Found a chip that will do this: SN74LVC1G19 (has two OR and one NOT)
