General Description
The HV5308B and HV5408B are low voltage serial to high
voltage parallel converters with push-pull outputs. These
devices have been designed for use as drivers for AC-
electroluminescent displays. They can also be used in any
application requiring multiple output high voltage current
sourcing and sinking capabilities, such as driving plasma
panels, vacuum fluorescent, or large matrix LCD displays.
These devices consist of a 32-bit shift register, 32 latches, and
control logic to enable outputs. Q1 is connected to the first
stage of the shift register through the Output Enable logic. Data
is shifted through the shift register on the low to high transition
of the clock. The HV5408B shifts in the counterclockwise
direction when viewed from the top of the package, while the
HV5308B shifts in the clockwise direction. A data output buffer
is provided for cascading devices. This output reflects the
current status of the last bit of the shift register (32). Operation
of the shift register is not affected by the LE (latch enable) or
the OE (output enable) inputs. Transfer of data from the shift
register to the latch occurs when the LE input is high. The
data in the latch is retained when LE is low.

Notes:
1. Device will survive (but operation may not be specified or guaranteed) at
these extremes.
2. All voltages are referenced to GND.
3. Duty cycle is limited by the total power dissipated in the package.
4. For operation above 25°C ambient derate linearly to maximum operating
temperature at 20mW/°C for plastic and at 15mW/°C for ceramic.

Data shift register clock

Description
Input are shifted into the shift register on the positive edge of the clock.
When LE is HIGH, shift register data is transferred into a data latch.
When LE is LOW, data is latched, and new data can be clocked into the
shift register.
When OE is LOW, all HV outputs are forced into a LOW state, regardless
of data in each channel. When OE is HIGH, all HV outputs reflect data
latched.
Data needs to be present before each rising edge of the clock.
Data output for cascading to the data input of the next device.
High voltage push-pull outputs, which, depending on controlling low
voltage data, can drive loads either to a GND, or to V
PP
rail levels.
