HV57009 64-Channel Serial to Parallel Converter with P-Channel Open Drain Controllable Output Current Features General Description The HV57009 is a low-voltage serial to high-voltage parallel HVCMOS technology converter with P-channel open drain outputs. This device has 5.0V CMOS Logic been designed for use as a driver for plasma panels. Output voltage up to -85V Output current source control The device has two parallel 32-bit shift registers, permitting data 16MHz equivalent data rate rates twice the speed of one (they are clocked together). There Latched data outputs are also 64 latches and control logic to perform the blanking of the outputs. HV 1 is connected to the rst stage of the rst Forward and reverse shifting options (DIR pin) OUT shift register through the blanking logic. Data is shifted through Diode to VDD allows efcient power recovery the shift registers on the logic low to high transition of the clock. Hi-Rel processing available The DIR pin causes CCW shifting when connected to VSS, and CW shifting when connected to VDD. A data output buffer is provided for cascading devices. This output reects the current status of the last bit of the shift register (HV 64). Operation of OUT the shift register is not affected by the LE (latch enable), or the BL (blanking) inputs. Transfer of data from the shift registers to latches occurs when the LE input is high. The data in the latches is stored when LE is low. The HV570 has 64 channels of output constant current sourcing capability. They are adjustable from 0.1 to 2.0mA through one external resistor or a current source.
