The LSF0102DQER from NXP is a 2-bit bidirectional voltage-level translator supporting 1.0V-4.5V on side A and 1.0V-5.5V on side B. It handles push-pull, open-drain, and I2C signaling at >100 Mbps, making it versatile for mixed-voltage system interfacing.<\/p>\n

Pass-gate architecture with external pull-up resistors on each I\/O enables bidirectional translation. EN input enables\/disables all channels. The LSF family supports any combination of voltages within range, unlike fixed-direction translators. Open-drain mode is achieved by external pull-ups on both sides.<\/p>\n
