HV7022中文资料34-Channel, Symmetric Row Driver, 230V数据手册Microchip规格书

描述 Description

The HV7022C is a low-voltage serial to high-voltage parallel converter with push-pull outputs. It is especially suited for use as a symmetric row driver in AC thin-film electroluminescent (ACTFEL) displays. The HV7022C offers 34 output lines, a direction (DIR) pin to give CW or CCW shift register loading, output enable (OE), and polarity (POL) control. After data is entered (on the falling edge of CLK), a logic high will cause the output to swing to VPP if POL is high, or to GND if POL is low.

特性 Features

• HVCMOS® technology
• Symmetric row drive (reduces latent imaging in ACTFEL displays)
• Output voltage up to +230V
• Low power level shifting
• Source/sink current minimum 70mA
• Shift register speed 4.0MHz
• Pin-programmable shift direction

简介

HV7022属于集成电路（IC）的移位寄存器。由Microchip制造生产的HV7022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。
