LSF0102; LSF0202
2-bit bidirectional multi-voltage level translator; open-drain; push-pull
The LSF0102 and LSF0202 are both 2 channel bidirectional multi-voltage level translators for open-drain and push-pull applications. The LSF0102 and LSF0202 support up to 100 MHz up translation and ≥100 MHz down translation at ≤ 30 pF capacitive load. There is no need for a direction pin which minimizes system effort. Both support 5 V tolerant I/O pins for compatibility with TTL levels in a variety of applications. The ability to set up different voltage translation levels on each channel makes the device very flexible and suitable for a lot of different applications.
LSF0102 and LSF0202 differ in pin assignment only.
