The LSF family of bi-directional voltage level
translators from TexasInstruments (TI) operate from 0.8V to 4.5V
(Vref_A) and 1.8V to 5.5V(Vref_B). This allows bi-directional voltage
translations between 0.8V and5V without the need for a direction
terminal in open-drain or push-pullapplications.
The
devices support level translation applications with transmission
speedsgreater than 100 MHz for open-drain systems utilizing a 15pF
capacitance and165ohm pull-up resistor.
The
device allows a seamless translation between higher and lower
voltagesselected by the user without the need for directional control.
