1.8V to 3.3V level conversion chip

Other Parts Discussed in Thread: TXS0104E, TXS0102, SN74LVC1G07

At present, the PCIE design process requires a 1.8V to 3.3V level conversion chip with open leakage output. The electrical characteristics are as follows:

1.8V input VIL(MAX)≥0.45V; VIH (MIN) 1.35 or less

3.3V Output VOL (MAX) ≤0.2V; VOH (MAX) ≤3.8V

Please help to recommend an available type of open leakage output converter chip

Hey Zhang,

The TXS0108 supports that level shift range and open-drain signals. It also comes in a 4 ch (TXS0104E) version and 2 ch (TXS0102) version if needed.

The simplest solution is an open-drain buffer like the SN74LVC1G07 with VCC = 1.8 V.

Instead of LVC, use AUC for high speed, or AUP for low power. There are also devices for more channels (2G, 3G).
