HV3418中文资料64-Channel, 180V, Push/Pull, Ruggedized Series to Parallel Converter数据手册Microchip规格书

描述 Description

The HV3418 is alow voltage serial to high voltage parallel converter with push-pull outputs. This device has been designed for use as a printer driver for inkjet applications. It can also be used in any application requiring multiple output, high voltage, low current sourcing and sinking capabilities. The device consists of a 64-bit shift register, 64 latches, and control logic to perform the polarity select and blanking of the outputs. A DIR pin controls the direction of data shift through the device. With DIR grounded, DIOA is Data-In and DIOB is Data-Out; data is shifted from HVOUT64 to HVOUT1. When DIR is at logic high, DIOB is Data-In and DIOA is Data-Out: data is then shifted from HVOUT1 to HVOUT64. Data is shifted through the shift register on the low to high transition of the clock. Data output buffers are provided for cascading devices. Operation of the shift register is not affected by the LE (latch enable), BL (blanking), or the POL(polarity) inputs. Transfer of data from the shift register to the latch occurs when the LE (latch enable) is high. The data in the latch is stored during LE transition from high to low.

简介

HV3418属于集成电路（IC）的移位寄存器。由制造生产的HV3418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。
