HV7620中文资料40MHz, 32-Channel Serial to Parallel Converter w/ Push Pull Output数据手册Microchip规格书

描述 Description

The HV7620 is a low-voltage serial to high-voltage parallel converter with push-pull outputs. This device has been designed for use as a driver for color AC plasma displays.The device has 4 parallel 8-bit shift registers permitting data rates four times the speed of one. The data is clocked in simultaneously on all four data inputs with a single clock. Data is shifted in on a low to high transition of the clock. The latches and control logic perform the output enable function.The DIR pin causes clockwise (CW) shifting of the data when connected to VDD1, and counterclockwise (CCW) shifting when connected to LVGND. Operation of the shift register is not affected by the LE (latch enable) input. Transfer of data from the shift registers to the latches occurs when the LE input is high. Data is stored in the latches when LEis low.The current source on the logic inputs provides active pull up when the input pins are open.

简介

HV7620属于集成电路（IC）的移位寄存器。由制造生产的HV7620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。
