0MHz ►► Strobe and enable inputs ►► CMOS compatible inputs ►► Forward and reverse shifting options ►► Hi-Rel processing available General Description The HV5122 is a low voltage serial to high voltage parallel converter with open drain outputs.
This device has been designed for use as a driver for AC electroluminescent displays.
They can also be used in any application requiring multiple output high voltage current sinking capabilities such as driving inkjet and electrostatic print heads, plasma panels, vacuum fluorescent, or large matrix LCD displays.
This device consists of a 32-bit shift register and control logic to perform the Output Enable and all-on functions.
Data is shifted through the shift register on the high to low transition of the clock.
The HV5122 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.
Operation of the shift register is not affected by the OE(Output Enable) or the STR(Strobe) inputs.
The HV5122 has been designed to be used in systems which either switch off the high voltage supply before changing the state of the high voltage outputs or which limit the current through each output.
