Use TXU0304 + TXU0102 (or TXU0104 + TXU0202), or 2× TXU0304 to simplify the BOM.
If you want a single chip, you have to use an unbuffered translator like the LSF0108 or TXS0108E.
Hi Shifali,
I agree with Clemens' recommendations here. The best choice for this application would be the TXU0102 but if the TXS0102 must be used in this case, the external pullups is suggested to be removed, otherwise similar behavior to TXB0102 that…
Part Number: LSF0002 Other Parts Discussed in Thread: SN74AXC2T45 , TXU0102 Tool/software: Hi Sir,
customer using LSF0002 for 70MHz signal but looks waveform abnormal when f>2MHz.
Do you have idea for this? thanks.
thanks, Ian.
You are connecting the outputs of the 1.8 V MCU to the 1.8 V inputs of the level shifter; this is the same and is OK.
For two signals, the TXU0102 would be a simpler choice.
The LSF is a passive switch. For high input voltages (VREF_A or higher), the switch is open, and the output voltage is determined only by the pull-up resistor. For low input voltages (below VREF_A), the switch is closed, and the corresponding Ax and Bx…
Hello Clemens Ladisch ,
Thanks for the clarification & the inputs!
I came across this graph in the LVC family in the Maximum Input/Output Voltage section & this graph suggests that the voltages gine beyond 7V approaching ~9V while the AMR for the '245…
Part Number: TXB0102 Other Parts Discussed in Thread: TXU0102 Tool/software:
In the datasheet of TXB0102, why should the VCCA<=VCCB? The architecture of TXB is symmetrical.
The TXB must not be used with strong pull-up/-down resistors (< 20 kΩ); see section 8.4.2 of the datasheet.
For unidirectional signals, you should use a unidirectional translator like the TXU0102. Are the directions of the two GPIO signals fixed…
