General Description
The HV506 is a low-voltage serial to high-voltage parallel con-
verter with push-pull outputs. It is especially suitable for use as
a symmetric row driver in AC thin-film electroluminescent
(ACTFEL) displays.
When the data reset pin (DR
outputs of the internal shift register to zero. At the same time, the
output of the shift register will start shifting a logic high from the
least significant bit to the most significant bit. The DR
triggered at any time. The DIR pin controls the direction of data
through the device. When DIR is at logic high, DR
and DR
and the DR
Table for output sequence. The POL and OE pins perform the
polarity select and output enable function respectively. Data is
clocked through the shift register loaded on the low to high
transition of the clock. A logic high in the shift register will cause
the other corresponding output to swing to V

If OE is at logic high all outputs will be in the High-Z state. An
output in the High-Z state may block up to 275V above V
