max303The MAX303 is a precision, dual, hh-speed switch. The single-pole double-throw (SPDT) MAX303 has two normally open (NO) and two normally closed (NC) poles. This part offers(V+ = +12V, V- = 0V, GND = 0V, VAH = +2.4V, VAL = +0.8V, TA = TMIN to TMAX, unless otherwise noted.) Note 2: The algebraic convention where the most negative value is a
