HV9308/HV9408

32-Channel Serial-to-Parallel Converters with High-Voltage Push-Pull Outputs

Features

General Description

• 5V CMOS Compatible Inputs

• Low-Power Level Shifting

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

capabilities, such as driving plasma panels, vacuum

fluorescent displays, and large matrix LCD displays.

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. HV_OUT1 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

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

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.
