This device consists of a 32-bit shift register, 32 data latches, and control logic to perform polarity and blanking functions. Data is shifted through the shift register on the logic high-tolow transition of the clock. The HV4522 shifts in the counter clockwise direction (when viewed from the top of the package). A data output buffer is provided for cascading devices. This output reflects the current status of the last bit of the shift register. The data in the shift register is latched when the latch enable pin is brought to logic high, and then returned to ground. If the latch enable pin is held high, the latch becomes transparent and the shift register data is directly reflected in the outputs.
