HV5622

32-Channel Serial to Parallel Converter

With Open Drain Outputs

General Description

Features

► Processed with HVCMOS^®technology

► Sink current minimum 100mA

► Shift register speed 8.0MHz

► Polarity and Blanking inputs

► CMOS compatible inputs

The HV5622 is a low-voltage serial to high-voltage parallel

converter with open drain outputs. This device has been designed

for use as a driver for AC-electroluminescent displays. It 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.

► Forward and reverse shifting options

► 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.
