General Description

The HV570 is a low-voltage serial to high-voltage parallel

converter 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 rates twice the speed of one (they are clocked together).

There are also 64 latches and control logic to perform the

blanking of the outputs. HVOUT1 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 VSS, and CW shifting when connected to

VDD. A data output buffer is provided for cascading devices.

This output reflects the current status of the last bit of the

shift register (HVOUT64). 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.

Note:

Each SR (shift register) provides 32 outputs. SR1 supplies outputs 1 to 32 and SR2 supplies outputs 33 to 64.
