32-Channel Serial To Parallel Converter

With Open Drain Outputs

General Description

The HV55 and HV56 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 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 HV55 shifts in the counterclockwise

direction when viewed from the top of the package, and the HV56

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 (latch enable) input is high. The data in the

latch is stored when LE is low.
