General Description
The HV7620 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 color AC plasma displays.
The device has 4 parallel 8-bit shift registers permitting data rates
four times the speed of one. The data is clocked in simultaneously
on all four data inputs with a single clock. Data is shifted in on a
low to high transition of the clock. The latches and control logic
perform the output enable function.
The DIR pin causes clockwise (CW) shifting of the data when
connected to VDD1, and counterclockwise (CCW) shifting when
connected to LVGND. Operation of the shift register is not affected
by the LE (latch enable) input. Transfer of data from the shift
registers to the latches occurs when the LE input is high. Data is
stored in the latches when LE is low. The current source on the
logic inputs provides active pull up when the input pins are open.

Absolute Maximum Ratings are those values beyond which damage to the
device may occur. Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level may affect
device reliability. All voltages are referenced to device ground.
Notes:
1. For operation above 25°C ambient derate linearly to maximum
operating temperature at 20mW/°C.
