SN74LV1T34: 3.3V to 1.8V at 27Mhz

Part Number: SN74LV1T34
Other Parts Discussed in Thread: SN74AVC1T45, SN74AXC1T45

Tool/software:

Seeking to level shift 3.3V to 1.8V at 27MHz. Datasheet only characterizes 1.8V output prop delay at 15Mhz, but I'm not overly concerned with prop delay as long as the output waveform looks good.

Hi Daniel,

Yes, LV1T works. You may also see SN74AVC1T45 or SN74AXC1T45, thanks.

Best Regards,

Michael.

Other than the higher data rates, is there an advantage to using these dual supply devices? It will complicate our PCB layout.

Hi Daniel,

No both options works great as it mainly depends on which case is applicable i.e dual supply may be later configured for A to B or B to A (3.3 V to 1.8 V and vice-versa) while single supply will be for a fixed output similar to Vcc supply, thanks.

Best Regards,

Michael.
