HV510

The HV510 is a low voltage serial to high voltage parallel converter with 12 high voltage push-pull outputs. This device has been designed to drive small capacitive loads such as piezo electric transducers. It can also be used in any application requiring multiple high voltage outputs, low current sourcing and sinking capabilities.

The device HV510 consists of a 12-bit shift register, 12 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, DIOA is Data In and DIOB is Data Out; data is shifted from HVOUT12 to HVOUT1. When DIR is at logic high, DIOB is Data In and DIOA is Data Out: data is then shifted from HVOUT1 to HVOUT12. Data is shifted through the shift register on the low to high transition of the clock. Data output buffers are provided by HV510 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.
