... Ordering number : ENN6235 Overview The LC75844M is a 1/4 duty general-purpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75844M can drive an LCD with segments directly. The LC75844M can also control general-purpose output ports. Since the LC75844M uses separate power ...
