MAX3000EEUP+ datasheet: http://datasheets.maximintegrated.com/en/ds/MAX3000E-MAX3012.pdf

I have a project that uses 3.3v SPI format communication from a few different chips to an Arduino Uno at 5v logic. The system works when I use the sparkfun logic level converters, but when I implement the MAX3000EEUP+, it doesn't show any signs of pass-through. The MAX3000EEUP+ is in a TSSOP package. The chips I'm communicating with are the MAX31855K and MAX31865.
[3v3 SPI CLK] to [Sparkfun LV TX], [Sparkfun HV TX] to [Uno D13]
[3v3 SPI CS] to [Sparkfun LV RX], [Sparkfun HV RX] to [Uno D10]
[3v3 SPI DO] to [Uno D12] directly
NOT working setup:
[3v3 SPI SCK] to [MAX3000EEUP+ Pin5], [MAX3000EEUP+ Pin16] to [Uno D13]
[3v3 SPI CS] to [MAX3000EEUP+ Pin4], [MAX3000EEUP+ Pin17] to [Uno D10]
[3v3 SPI DO] to [MAX3000EEUP+ Pin3], [MAX3000EEUP+ Pin18] to [Uno D12]
[5v] to [MAX3000EEUP+ Pin19]
[3v3] to [MAX3000EEUP+ Pin2]
[GND] to [MAX3000EEUP+ Pin11]
[MAX3000EEUP+ Pin10] to [10k resistor] to [5v]
Any ideas why it's not working with the Max3000EEUP+?
