DS90LT012AQ-Q1: need pullup/down resistor

Part Number: DS90LT012AQ-Q1

Hello team,

My customer want  to confirm the design of DS90LT012AQ-Q1.

Must the input of DS90LT012AQ-Q1 be required by adding pullup/down resistor in case they don't need fail safe circuit function?

if not, The value of Vth is 0V and the value of VTL is -100mV?
