HV9408

32-Channel Serial to Parallel Converter

With High Voltage Push-Pull Outputs

Features

General Description

► Processed with HVCMOS^®technology

► Low power level shifting

The HV9408 is a low voltage serial to high voltage parallel

converter with push-pull outputs. This device has been designed

for use as a driver for AC-electroluminescent displays. It 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.

► Shift register speed 8.0MHz

► Latched data outputs

► 5.0V CMOS compatible inputs

► Diode to V_PPallows efﬁcient power recovery

This device consists of a 32-bit shift register, 32 latches, and

control logic to enable 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 HV9408 shifts in the counter-clockwise direction

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

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.
