HV57009

64-Channel Serial To Parallel Converter

With P-Channel Open Drain Controllable Output Current

General Description

The HV570 is a low-voltage serial to high-voltage parallel con-
verter with P-channel open drain outputs. This device has been
designed for use as a driver for plasma panels.

The device has two parallel 32-bit shift registers, permitting data
rate twice the speed of one (they are clocked together). There
are also 64 latches and control logic to perform the blanking of
the outputs. HV

OUT

1 is connected to the first stage of the first shift

register through the blanking logic. Data is shifted through the
shift registers on the logic low to high transition of the clock. The
DIR pin causes CCW shifting when connected to V

, and CW

shifting when connected to V

. A data output buffer is provided

for cascading devices. This output reflects the current status of
the last bit of the shift register (HV

OUT

64). Operation of the shift

register is not affected by the LE (latch enable), or the BL
(blanking) inputs. Transfer of data from the shift registers to
latches occurs when the LE input is high. The data in the latches
is stored when LE is low.

The HV570 has 64 channels of output constant current sourcing
capability. They are adjustable from 0.1 to 2.0mA through one
external resistor or a current source.

Since I

REF

Therefore, if I

OUT

= 2mA and V

REF

= -5V

EXT

= 2.5K

If I

OUT

= 1mA and R

EXT

REF

= -1V.

If R

EXT

>10K

, add series network R

and C

to ground for

stability as shown.

This control method behaves linearly as long as the operational
amplifier is not saturated. However, it requires a negative power
source and needs to provide a current I

REF

= I

OUT

for each HV570

chip being controlled.

If HV

OUT

+1V, the HV

OUT

cascode may no longer operate as a

perfect current source, and the output current will diminish. This
effect depends on the magnitude of the output current.

Given I

OUT

and V

REF

, the R

EXT

can be calculated by using:

EXT

REF

OUT

The intersection of a set of I

OUT

and V

REF

values can be located

in the graph shown below. The value picked for R

EXT

must always

be in the shaded area for linear operation. This control method
has the advantage that V

REF

is positive, and draws only leakage

current. If R

EXT

> 10K, add series network R

and C

to ground

for stability as shown.

Note: Lower reference current I

REF

, results in higher distortion,

, on the output.

*Required if R

EXT

> 10K or R

EXT

is replaced by a constant

current source.
