HV9308 32-Channel Serial to Parallel Converter With High Voltage Push-Pull Outputs Features General Description Processed with HVCMOS technology The HV9308 is a low voltage serial to high voltage parallel converter with push-pull outputs. This device has been designed Low power level shifting for use as a driver for AC-electroluminescent displays. It can also Shift register speed 8.0MHz be used in any application requiring multiple output, high voltage Latched data outputs current sourcing and sinking capabilities such as driving plasma 5.0V CMOS compatible inputs panels, vacuum fluorescent, or large matrix LCD displays. Diode to V allows efficient power recovery PP This device consists of a 32-bit shift register, 32 latches, and control logic to enable outputs. HV 1 is connected to the first OUT stage of the shift register through the Output Enable logic. Data is shifted through the shift register on the low to high transition of the clock. The HV9308 shifts in the 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 (32). Operation of the shift register is not affected by the LE (latch enable) or the OE (output enable) inputs. Transfer of data from the shift register to the latch occurs when the LE input is high. The data in the latch is retained when LE is low.
