HV507

The HV507 is a low voltage serial to high voltage parallel converter with 64 high voltage push-pull outputs. This device has been designed for use as a printer driver for electrostatic applications. It can also be used in any application requiring multiple high voltage outputs, low current sourcing and sinking capabilities.

The device HV507 consists of a 64-bit shift register, 64 latches, and control logic to perform the polarity select and blanking of the outputs. A DIR pin controls the direction of data shift through the device. With DIR grounded, D_IOA is Data In and D_IOB is Data Out; data is shifted from HVOUT64 to HVOUT1. When DIR is at logic high, D_IOB is Data In and D_IOA is Data Out: data is then shifted from HV_OUT1 to HV_OUT64. Data is shifted through the shift register on the low to high transition of the clock. Data output buffers are provided for cascading devices. Operation of the shift register is not affected by the LE, BL, or the POL inputs. Transfer of data from the shift register to the latch occurs when the LE is high. The data in the latch is stored during LE transition from high to low,that is the info about HV507.
