8 V to 4.
5 V (Vref_A) and 1.
8 V to 5.
5 V (Vref_B).
This range allows for bidirectional voltage translations between 0.
8 V and 5.
0 V without the need for a direction terminal in open-drain or push-pull applications.
The LSF family supports level translation applications with transmission speeds greater than 100 MHz for opendrain systems that utilize a 15-pF capacitance and 165-Ω pull-up resistor.
When the An or Bn port is LOW, the switch is in the ON-state and a low resistance connection exists between the An and Bn ports.
The low Ron of the switch allows connections to be made with minimal propagation delay and signal distortion.
