SN74LVC1G126: SN74LVC1G126 VS SN74LVC1G125 (Alternative part)

GOH HWA
Prodigy 10 points
Part Number: SN74LVC1G126
Other Parts Discussed in Thread: SN74LVC1G125, , SN74AHC1G125, SN74AUP1G125

Both parts SN74LVC1G125 & 126 testing on the same test parameter “ Sensor Status Bits Test ” .  The SN74LVC1G126 is an alternative MPN for SN74LVC1G125 .

Unfortunately for MPN126 the Safety Fault Bit Expected Off “0” but Actual On “1”

Based on datasheet between these two MPN, can we say that these two components have different logic gate and functionality?  

May I know these two MPN125 &126 logically can use in the same PCBA circuity? 

May I know that MPN SN74LVC1G126 logically can use as alternative part for MPN SN74LVC1G125?

SN74LVC1G126 & SN74LVC1G125 equivalent specification? 

SN74LVC1G126 & SN74LVC1G125 same output?

    The only difference between '125 and '126 is the polarity of the /OE or OE input. This is shown in the functional block diagram, and in the device functional modes table.

    If you want an alternative for the SN74LVC1G125, use the SN74AHC1G125 (lower drive strength) or SN74AUP1G125 (3.3 V or lower, lower drive strength).
