HV6008

The HV6008 is a 32-channel liquid crystal display driver with 3-state DMOS outputs. Each output can be set to +40V, -40V, or GND. A symmetric waveform can be applied to a capacitive load using the phase shift feature of the HV60.

The HV6008 consists of a 32-bit shift register with Clear, Enable, and Phase Shift logic, and 32 high voltage output buffers. With the Enable pin held low, all outputs are placed in the return to zero (GND) state. When Enable is high, each output reflects the data in its shift register bit. All outputs with a logic "0" in their shift register will be in the return to zero state. Outputs with a logic "1" in their shift register will reflect the state of the phase shift pin. These outputs will be switched to VPP when phase shift is high and VNN when phase shift is logic "0".

Additional functions provided by HV6008 are Shift Register Clear and Data Out. All bits of the shift register are changed to logic "0" when Clear is pulled low. With Clear at a logic "1", normal shift register operation proceeds. The data output reflects the status of the 32nd shift register stage.
