General Description

The HV93 and HV94 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. HV

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 HV94 shifts in the counterclockwise direction when

viewed from the top of the package and the HV93 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.

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.
