SN74LVC08A: SN74LVC08A --misoperation --when Vin=1.5V

Part Number: SN74LVC08A
Other Parts Discussed in Thread: SN74AUP1T08, SN74HCS08, TLV7011

the MCU output driect connect to SN74LVC08A input pin ,when the mcu init start ,there mcu has 1.5V  square output , then the SN74LVC08A will have 1.5V square output ,VCC of SN74LVC08A is 3.3V ,

SO the VIH  shoud be 2V,  if there any way to solve the misoperation , many thanks !

the picture 1 is input and output waveform  ,the picture 2 is input and VCC waveform ,about 1.5V .
