General Description
The HV76 is a low-voltage serial to high-voltage parallel con-
verter 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 rate
4 times the speed of one. The data are clocked in simultaneously
on all four data inputs with a single clock. Data are 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 V
, and counterclockwise (CCW) shifting when
connected to GND. 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.
