LND-SP64HV

32MHZ, 64 CHANNEL SERIAL TO PARALLEL CONVERTER WITH PUSH-PULL OUTPUTS

Features

as driving plasma panels, vacuum fluorescent displays,

or large matrix LCD displays.



HVCMOS^®Technology

5.0V CMOS Logic

Output voltage up to +90V

Low power level shifting

32MHz equivalent data rate

Latched data outputs

Forward and reverse shifting options (DIR pin)

Diode to V_PPallows efficient power recovery

Outputs may be hot switched

Hi-Rel processing available

The device has 4 parallel 16-bit registers, permitting data

rates 4x the speed of one (they are clocked together).

There are also 64 latches and control logic to perform the

polarity select and blanking of the outputs. HV_OUT1 is

connected to the first stage of the first shift register

through the polarity and blanking logic. Data is shifted

through the shift registers on the logic low to high

transition of the clock. The DIR pin causes CCW shifting

when connected to GND, and CW shifting when

connected to V_DD. A data output buffer is provided for

cascading devices. This output reflects the current status

of the last bit of the shift register (HV_OUT64). Operation of

General Description

The LND-SP64HV is a low voltage serial to high voltage

parallel converter with push-pull outputs. The device has

been designed for use as a driver for EL displays. It can

also be used in any application requiring multiple output
