HV4622

32-Channel Serial to Parallel Converter

with P-Channel Open Drain Outputs

Features

General Description

► Processed with HVCMOS^®Technology

► Output voltages to -220V

► Source current minimum 60mA

► Shift register speed 8.0MHz

► Polarity and blanking inputs

► CMOS compatible inputs

► Forward and reverse shifting options

The HV4622 is a low-voltage serial to high-voltage parallel

converter with P-Channel open drain outputs. This device has

been designed for use a driver for AC-electroluminescent

displays. It 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.

► Can be used with the HV5622 to provide 220V

This device consists 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 HV4622 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. The data in the shift

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 reﬂected in the outputs.

push-pull operation

► 44-lead PLCC surface mount package

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

HV4622 can be paired with the HV5622.
