Overview
TC4511B is a decoder that converts the input of BCD code into the 7-segment display element driving signal and the output has a complementary connection of NPN bipolar transistor and N-channel MOSFET. Therefore, not only has the capability of directly driving cathode common type LED, this has the capability of driving various display elements with simple interface circuits.
(LT)’ input and (BI)’ input are to force all the outputs to be “H” (illuminated) and “L” (not illuminated) respectively regardless of BCD input. As the latch controlled by common LE input is inserted in each of the four input lines, a static display of dynamic information can be achieved. When an invalid BCD input, “10” or higher is applied, all the outputs become “L” (not illuminated).
