TXS0108E: TXS0108 consumption current

Lucifer

Part Number: TXS0108E

Dear Sir,

for power source evaluation, I am calculating the consumption current of TXS0104 and TXS0108. Since I can't find the specification in the datasheet. may help provide it for evaluation? Thanks.

Table 6.5 of the datasheet specifies the static power consumption (I_CCA, I_CCB), table 6.16 the dynamic one (C_pd). (See the FAQ for what this means.)

Additionally, when you pull any pin low, there will be current and an associated voltage drop over the pull-up resistors and the pass-gate transistor; see sections 8.2/8.3 for their values.

Dear Sir,
I check the datahseet of txs0108 8bit consumption current is lower than Txs0104 4 bit, does it mean TXS0108 is more power saving , right? Am I wrong, please correct me, Thanks.
TXS0104 Icca+Iccb =max14.4uA,
TXS0108 Icca+Iccb= max 8uA

The other currents (see my answer above) are likely to be much larger.
