The HV04H and HV06H are low voltage serial to high voltage parallel converters with open drain outputs. These devices have been designed for use as drivers for AC-electroluminescent displays. They can also be used in any application requiring multiple output high voltage current sinking capabilities such as driving inkjet and electrostatic print heads, plasma panels, vacuum fluorescent, or large matrix LCD displays. These devices consist of a 64-bit shift register, 64 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 HV04H shifts in the counterclockwise direction when viewed from the top of the package and the HV06H shifts in the clockwise direction. 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 Each enable) input is high. The data in the latch is stored when LE is low. The HV04H and HVOGH devices are ruggedized versions of our standard HV04H and HV06H. They are designed to be used in circuits where ramping of the high voltage supply is not feasible. Care must betaken to limit the load capacitance and surge current in any particular application.
The features of HV04H/HV06H can be summarized as (1)HVCMOS technology; (2)output voltages up to 90V using a ramped supply; (3)low power level shifting; (4)shift register speed 8 MHz; (5)latched outputs; (6)output polarity and blanking; (7)CMOS compatible inputs; (8)forward and reverse shifting options.
The absolute maximum ratings of HV04H/HV06H are (1)supply voltage, VDD: -0.5V to +15V; (2)supply voltage, VPP: -0.5V to +80V; (3)logic input levels: -0.5V to VDD +0.5V; (4)ground currents: 3.0A; (5)continuous total power dissipationt ceramic: 1900mW/Plastic: 1200mW; (6)operating temperature range commercial: -40°C to +85°C/military -55°C to +125°C; (7)storage temperature range: -65°C to 150°C.
