General Description

The HV45 and HV46 are low-voltage serial to high-voltage

parallel converters with P-Channel open drain outputs. These

devices have been designed for use as drivers for AC-electrolu-

minescent displays. They can also be used in any application

requiring multiple output high-voltage current source capabilities

such as driving inkjet and electrostatic print heads, plasma

panels, or vacuum fluorescent displays.

These devices consist of a 32-bit shift register, 32 data latches,

and control logic to perform polarity and blanking functions. Data

is shifted through the shift register on the logic high-to-low

transition of the clock. The HV45 shifts in the counterclockwise

direction when viewed from the top of the package and the HV46

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. The data in the shift register is

latched when the latch enable pin is brought to logic high and then

returned to ground. If the latch enable pin is held high, the latch

becomes transparent and the shift register data is directly re-

flected in the outputs.

For applications requiring active pull down as well as pull up, the

HV45 and HV46 can be paired with the HV55 and HV56 devices,

respectively.
