LVC inputs are overvoltage tolerant, so you can use it for shifting down. But the LVC switching thresholds do not allow 3.3 V signals with a 5 V supply; use a device wither lower thresholds (e.g., SN74AHCT125) for that. If you need Schmitt-trigger inputs…
For shifting to a lower voltage, you can use any buffer with an overvoltage-tolerant input, e.g., SN74AHCT1G125-Q1, SN74LVC1G125-Q1, or SN74LVC1G17-G1 (these have compatible footprints).
For shifting from 3.3 V to 5 V, you can use any buffer with TTL…
The LSF does not buffer the signals (it is a passive switch), and works best for open-drain signals.
Op-amps are for analog signals. For digital signals, you can simply use plain logic buffers. To convert from 3.3 V to 5 V, use a buffer with TTL-compatible…
Part Number: SN74ACT244 Other Parts Discussed in Thread: UCC23513 , SN74AHCT125 , SN74AHCT125-Q1 Hi team,
Can you help advise if we have four-channel version buffer/driver similar as SN74ACT244?
My customer is utilizing SN74ACT244 to work with UCC23513…
Part Number: SN74LVC07A Other Parts Discussed in Thread: SN74LVC1G07 , SN74AHCT125 , SN74LVC2G34 Hi Team,
We are using SN74LVC07A and configure as SPI level shift, schematic shows as below. VCC is 3.3V and using 5V pull up power at output side.
we set…
The SN74LVC3G17 was designed for input signals with the same voltage.
The SN74LV4T125 would work, but for 3.3 V to 5 V translation, you can simply use any buffer with TTL-compatible inputs, such as the SN74AHCT125.

Hi,
my customer need level shift for SPI and UART. And they may need 1 SPI master(3.3V) and several SPI slaves(5V)…
