HV9308/HV9408
32-Channel Serial-to-Parallel Converters with High-Voltage Push-Pull Outputs
Features
General Description
•
•
•
•
•
The HV9308 and HV9408 are low-voltage to
high-voltage serial-to-parallel converters with push-pull
outputs. These devices are designed as drivers for
AC-electroluminescent displays. They can also be
used in any application requiring multiple-output
high-voltage
low-current
sourcing-and-sinking
capabilities, such as driving plasma panels, vacuum
fluorescent displays, and large matrix LCD displays.
5V CMOS Compatible Inputs
Low-Power Level Shifting
8 MHz Shift Register Speed
Latched Data Outputs
Diode to VPP allows Efficient Power Recovery
Applications
•
•
•
•
Each device consists of a 32-bit Shift register, 32
latches and control logic to perform the polarity select
and blanking of the outputs. HVOUT1 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 HV9308
shifts
clockwise,
and
the
HV9408
shifts
counter-clockwise 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, 32. Operation of the Shift
register is not affected by the latch enable (LE) and the
output enable (OE) 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.

† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only, and functional operation of the device at those or any other conditions above those
indicated in the operational sections of this specification is not intended. Exposure to maximum rating conditions for
extended periods may affect device reliability.
Note 1: Duty cycle is limited by the total power dissipated in the package.
2: For operations above 25°C ambient, derate linearly to the maximum operating temperature at 20 mW/°C.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
