Part Number: TXB0304 Other Parts Discussed in Thread: TXU0304 , TXU0104 , TXU0204 The internal circuit output of the TXB0304 chip needs to pass through a 1K resistor, which will cause a resistor-impedance mismatch during high-speed signal conversion, causing…
For 1.2 V, the datasheet indeed does not specify any guaranteed limits. For practical purposes, the minimum usable supply voltage is 1.8 V.
What kind if signals do you want to translate? In most application, it is possible to use the TXU0104/TXU0204/TXU0304…
Part Number: TXB0104-Q1 Other Parts Discussed in Thread: SN74AVC4T245-Q1 , TXU0304-Q1 , TXU0104-Q1 , TXU0204-Q1 May I ask what are the differences between the previous SN74AVC4T245-Q1 and SN54SLC8T245 chips and the current TXB chips?
The LSF is a passive switch. The pull-up resistor at the output will load the resistor divider.
What are the directions of the four signals at the LSF? If none of them are bidirectional, use a unidirectional translator like the TXU0104/TXU0204/TXU0304…
Part Number: TXB0108 Other Parts Discussed in Thread: TXU0204 , SN74LVC1G34 hello.
I intend to use the TXB0108 to translate my FPGA signals (1.8V) to/from several other components (3.3V)
My problem is as follows:
Most of these signal are 1:1, meaning one…
This device can support UART signals. However, all eight channels go in the same direction, which would not be useful for TX and RX. Consider a translator like the TXU0202, or TXU0204 for more channels.
All these translators support many MHz; there is…
In general, all LSF outputs require pull-up resistors. (Without them, you will not get any output voltage higher than VrefA.) See section 5.2 of the Voltage-Level Translation With the LSF Family Application Report .
All your signals are unidirectional…
This will work.
To avoid pulse width distortions of the clock signal due to the slower rising edges of the clock signals, I'd recommend a translator with push/pull outputs like the TXU0204.
Part Number: LSF0108 Other Parts Discussed in Thread: TXU0204 , TXB0108 hey i am a junior pcb design engineer and i have a project where i use the lsf0108 for a bidirectional voltage translation.
i need to know how much current i drive from the vcc in…
