HV66 32-Channel LCD Driver with Separate Backplane Output Features General Description HVCMOS technology The HV66 is a low voltage serial to high voltage parallel converter 32 push-pull CMOS output up to 60V with push-pull outputs. This device has been designed for use as a driver circuit for LCD displays. It can also be used in any appli- Low power level shifting cation requiring multiple output high voltage current sourcing and Shift register speed 5.0MHz sinking capabilities. The inputs are fully CMOS compatible. Latched data outputs Bidirectional shift register (DIR) The device consists of a 32-bit shift register, 32 latches, and con- Backplane output trol logic to perform blanking and polarity control of the outputs. HV 1 is connected to the first stage of the shift register. Data is OUT shifted through the shift register on the logic rising transition of the clock. A DIR pin causes data shifting clockwise when grounded and counter clockwise when connected to VDD. A data output buffer is provided for cascading devices. This output reflects the current status of the last bit of the shift register. Operation of the shift register is not affected by the LE (latch enable), BL (blank) or the POL (polarity) inputs. Transfer of data from the shift register to the latch occurs when the LE (latch enable) input is high. The data in the latch is stored after LE transitions from high to low.
