HV5622 32-Channel Serial to Parallel Converter With Open Drain Outputs Features General Description Processed with HVCMOS technology The HV5622 is a low-voltage serial to high-voltage parallel converter with open drain outputs. This device has been designed Sink current minimum 100mA for use as a driver for AC-electroluminescent displays. It can also Shift register speed 8.0MHz be used in any application requiring multiple output high voltage Polarity and Blanking inputs current sinking capabilities such as driving inkjet and electrostatic CMOS compatible inputs print heads, plasma panels, vacuum fluorescent, or large matrix Forward and reverse shifting options LCD displays. Diode to VPP allows efficient power recovery This device consists of a 32-bit shift register, 32 latches, and control logic to perform the polarity select and blanking of the outputs. Data is shifted through the shift register on the high to low transition of the clock. The HV5622 shifts in the clockwise direction when viewed from the top of the package. 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 (blanking), 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 when LE is low.
