HV9708中文资料32-Channel Serial to Parallel Converter With High Voltage Push-Pull Outputs数据手册Microchip规格书

描述 Description

The HV9708 is a low voltage serial to high voltage parallel converters with push-pull outputs. This device has been designed for use as a driver for AC-electroluminescent displays.It can also be used in any application requiring multiple output, high voltage current sourcing and sinking capabilities such as drivingplasma panels, vacuum fluorescent, orlarge matrix LCD displays. The inputs are fully CMOS compatible. This device consists of a 32-bit shift register, 32 latches, and control logic to perform the polarity select and blanking of the outputs. HVOUT1 is connected to the first stage of the shift register through the polarity and blanking logic. Data is shifted through the shift register on the logic low to high transition of the clock. The HV9708 shifts data 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 (HVOUT32). Operation of the shift register is not affected by the LE (latch enable), BL (blanking), or the POL (polarity) in-puts. Transfer of data from the shift register to the latch occurs when the LE (latch enable) input is high. The data in the latch is stored when LE is low.

简介

HV9708属于集成电路（IC）的移位寄存器。由Microchip制造生产的HV9708移位寄存器移位寄存器是低级逻辑器件，通常用于在串行和并行方式之间转换数字逻辑信号形式的数据，或在数字字内移动数据位的位置。移位寄存器通常使用集成到一个设备中的一组触发器来实现，常用于集成度更高的逻辑器件，但仍可用于 I/O 扩展等应用，在这些应用中离散形式的函数可能会非常有用。
