HV5522

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 HV5522 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 HV5522 shifts in the counter 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.
