NLSF595数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The NLSF595 is advanced CMOS shift register with open drain outputs fabricated with 0.6 5m silicon gate CMOS technology. This device is used in conjunction with a microcontroller, with only one dedicated line. All pins have Overvoltage Protection that allows voltages above VCC up to 7.0 V to be present on the pins without damage or disruption of operation of the part, regardless of the operating voltage. This device may be used between 2.0 and 5.5 volts, the output driver level may be independent of supply voltage:0-7.0 volts.

• ESD Performance: HBM > 1000 V; MM > 100 V
• Functionally Similar to the Popular 74VHC595

简介

NLSF595属于集成电路（IC）的LED驱动器。由制造生产的NLSF595LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
