Ordering Information
64-Channel Serial To Parallel Converter
With Open Drain Outputs
General Description
The HV31 is a low voltage serial to high voltage parallel converter
with open drain outputs. It has been designed especially for use
as a driver for electrostatic printers.
This device consists of a 64-bit shift register, 64 latches, latch
enable (LE), and output enable (OE). Data is shifted through the
shift register on the high to low transition of the clock. When the
DIR pin is set high, the HV31 shifts in the counterclockwise
direction when viewed from the top of the package. When the DIR
pin is set low, the HV31 shifts in the clockwise direction. A serial
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 LE or the OE
inputs. Transfer of data from the shift register to the latch occurs
when the LE input is high. The data in the latch is stored when LE
is low.
