HD61200 195 block function liquid crystal display driver circuit the combination of the data from the latch circuit 2 and m signal causes one of the 4 liquid crystal driver levels, v1, v2, v3, and v4 to be output. 80-bit latch circuit 2 the data from latch circuit 1 is latched at the fall of cl1 and output to liquid crystal display driver circuit. s/p serial/parallel conversion circuit which converts 1- bit data into 4-bit data. when shl is low level, data from dl is converted into 4-bit data and transferred to the latch circuit 1. in this case, dont connect any lines to terminal dr. when shl is high level, input data from terminal dr without connecting any lines to terminal dl. 80-bit latch circuit 1 the 4-bit data is latched at ? to ?0 and output to latch circuit 2. when shl is low level, the data from dl are latched in order of 1 ? 2 ? 3 ? ... 80 of each latch. when shl is high level, they are latched in a reverse order (80 ? 79 ? 78 ? ... 1). selector the selector decodes output signals from the counter and generates latch clock ? to ?0. when the lsi is not active, ? to ?0 are not generated, so the data at latch circuit 1 is stored even if input data (dl, dr) changes. control circuit controls operation: when e?/f (enable f/f) indicates 1, s/p conversion is started by inputting low level to e . after 80-bit data has been all converted, car output turns into low level and e?/f is reset to 0, and consequently the conversion stops. e?/f is rs flip-flop circuit which gives priority to set over reset and is set at high level of cl1. the counter consists of 7 bits, and the output signals upper 5 bits are transferred to the selector. car signal turns into high level at the rise of cl1. the number of bits that can be s/p-converted can be increased by connecting car terminal with e terminal of the next HD61200. free datasheet http://www..net/
