MIC4555中文资料SIM Card Level Shifter with 50mA LDO数据手册Microchip规格书

描述 Description

The MIC4555 is a digital level shifter with a 50mA LDO for SIM card interfaces. There are three high-speed level shifters for SIM card signal translation. The level shifters are designed to support high-speed clocking up to 5MHz. The 50mA LDO provides power for the SIM card to eliminate the need for a separate power device. This simplifies the design of the SIM card interface.

特性 Features

• Powers 1.8V or 3.0V SIM up to 50mA
• Input voltage range: 2.7V to 5.5V
• Controller voltage range: 1.6V to 5.5V
• Supports clock rates up to 5MHz
• 8kV ESD protection on SIM contact pins

简介

MIC4555属于集成电路（IC）的转换器电平移位器。由制造生产的MIC4555转换器，电平移位器逻辑转换器或电平移位器 IC 可用于在数字逻辑设备之间传递信息，这些设备可在不同/不兼容的供电电压下工作，或可实现不同的信令方式。例如，可以将需要 5 V 电源的数字输出传感器连接到具有 3.3 V I/O 电源的 FPGA，或者在 CMOS 或 TTL 等单端信令方式与 PECL 或 LVDS 等差分技术之间进行转换。
