General Description
Not recommended for new designs.
The HV60 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 HV60 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 鈥?鈥?in their shift
register will be in the return to zero state. Outputs with a logic 鈥?鈥?/div>
in their shift register will reflect the state of the phase shift pin.
These outputs will be switched to V
PP
when phase shift is high and
V
NN
when phase shift is logic 鈥?鈥?
Additional functions provided are Shift Register Clear and Data
Out. All bits of the shift register are changed to logic 鈥?鈥?when Clear
is pulled low. With Clear at a logic 鈥?鈥? normal shift register
operation proceeds. The data output reflects the status of the
32nd shift register stage.
